    Abstract

    We report a search for the charged-lepton flavor violation in Υ(2S) → ℓ<sup>∓</sup>τ<sup>±</sup> (ℓ = e, μ) decays using a 25 fb<sup>−1</sup> Υ(2S) sample collected by the Belle detector at the KEKB e<sup>+</sup>e<sup>−</sup> asymmetric-energy collider. We find no evidence for a signal and set upper limits on the branching fractions ($$ \mathcal{B} $$) at 90% confidence level. We obtain the most stringent upper limits: $$ \mathcal{B} $$(Υ(2S) → μ<sup>∓</sup>τ<sup>±</sup>) &lt; 0.23 × 10<sup>−6</sup> and $$ \mathcal{B} $$(Υ(2S) → e<sup>∓</sup>τ<sup>±</sup>) &lt; 1.12 × 10<sup>−6</sup>.

    A dark leptophilic scalar (φL) is a hypothetical particle that couples only to leptons rather than quarks. We report on a search for φL in the e+e-→τ+τ-φL, φL→ℓ+ℓ-(ℓ=e,μ) process using 626 fb-1 of data collected by the Belle experiment near the ϒ(4S) resonance. We validate the backgrounds with multiple control regions in data, using a novel multiclass multivariate event classifier. In absence of a signal, we quote upper limits at the 90% confidence level on the coupling between φL and leptons. Our bounds, obtained in a blinded approach, are 19% more constraining than the previous limits, averaged over the mass range 0.04≤mφL≤6.5 GeV. We exclude the parameter space below 4 GeV favored by measurement of the anomalous magnetic moment of the muon.

    We have analyzed 121.4 fb-1 of data collected at the ?(5S) resonance by the Belle experiment using the KEKB asymmetric-energy e+e- collider to search for the decay Bs0→J/ψπ0. We observe no signal and report an upper limit on the branching fraction B(Bs0→J/ψπ0) of 1.21×10-5 at 90% confidence level. This result is the most stringent, improving the previous bound by 2 orders of magnitude.

    We search for the baryon and lepton number violating charm decays, D→pℓ, where D is either a D0 or a D¯0 and ℓ is a muon or an electron, using a data sample of 921 fb-1 collected by the Belle detector at the KEKB asymmetric energy e+e- collider. In the absence of significant signals, we set upper limits on the branching fractions in the range (5-8)×10-7 at a 90% confidence level, depending on the decay mode.

    We observe the process ϒ(2S)→Ds(∗)+DsJ- and continuum production e+e-→Ds(∗)+DsJ- at s=10.52 GeV (and their charge conjugates) using the data samples collected by the Belle detector at KEKB, where DsJ- is Ds1(2536)- or Ds2∗(2573)-. Both DsJ- states are identified through their decay into K̄D¯(∗). We measure the products of branching fractions B(ϒ(2S)→Ds(∗)+DsJ-)B(DsJ-→K̄D¯(∗)) and the Born cross sections σBorn(e+e-→Ds(∗)+DsJ-)B(DsJ-→K̄D¯(∗)), and then compare the ratios R1B(ϒ(2S)→Ds(∗)+DsJ-)/B(ϒ(2S)→μ+μ-) for ϒ(2S) decays and R2σBorn(e+e-→Ds(∗)+DsJ-)/σBorn(e+e-→μ+μ-) for continuum production. We obtain R1/R2=9.7±2.3±1.1, 6.8±2.1±0.8, 10.2±3.3±2.5, and 3.4±2.1±0.8 for the Ds+Ds1(2536)-, Ds∗+Ds1(2536)-, Ds+Ds2∗(2573)-, and Ds∗+Ds2∗(2573)- final states in the DsJ-→K-D¯(∗)0 modes, respectively. The measured R1/R2 values indicate that the strong decay dominates in ϒ(2S)→Ds(∗)+DsJ- processes. We also measure the ratios of branching fractions B(Ds1(2536)-→KS0D∗(2010)-)/B(Ds1(2536)-→K-D∗(2007)0)=0.48±0.07±0.02 and B(Ds2∗(2573)-→KS0D-)/B(Ds2∗(2573)-→K-D0)=0.49±0.10±0.02, which are consistent with isospin symmetry. The second ratio is the first measurement of this quantity. Here, the first uncertainties are statistical and the second are systematic.

    We search for CP violation by measuring a T-odd asymmetry in the Cabibbo-suppressed D+→K+KS0π+π- decay, and in the Cabibbo-favored Ds+→K+KS0π+π- and D+→K+K-KS0π+ decays. We use 980 fb-1 of data collected by the Belle detector running at the KEKB asymmetric-energy e+e- collider. The CP-violating T-odd parameter aCPT-odd is measured to be aCPT-odd(D+→K+KS0π+π-)=(0.34±0.87±0.32)%, aCPT-odd(Ds+→K+KS0π+π-)=(-0.46±0.63±0.38)%, and aCPT-odd(D+→K+K-KS0π+)=(-3.34±2.66±0.35)%, where the first uncertainty is statistical and the second is systematic. We also report the first observation of the Cabibbo-suppressed decay Ds+→K+K-KS0π+. The branching fraction is measured relative to that of the analogous Cabibbo-favored decay: B(Ds+→K+K-KS0π+)/B(Ds+→K+KS0π+π-)=(1.36±0.15±0.04)%.

    The first simultaneous determination of the absolute value of the Cabibbo-Kobayashi-Maskawa matrix element Vub using inclusive and exclusive decays is performed with the full Belle data set at the (4S) resonance, corresponding to an integrated luminosity of 711 fb-1. We analyze collision events in which one B meson is fully reconstructed in hadronic modes. This allows for the reconstruction of the hadronic Xu system of the semileptonic b→uν¯ decay. We separate exclusive B→πν¯ decays from other inclusive B→Xuν¯ and backgrounds with a two-dimensional fit that utilizes the number of charged pions in the Xu system and the four-momentum transfer q2 between the B and Xu systems. Combining our measurement with information from lattice QCD and QCD calculations of the inclusive partial rate as well as external experimental information on the shape of the B→πν¯ form factor, we determine |Vubexcl|=(3.78±0.23±0.16±0.14)×10-3 and |Vubincl|=(3.88±0.20±0.31±0.09)×10-3, respectively, with the uncertainties being the statistical error, systematic errors, and theory errors. The ratio of |Vubexcl|/|Vubincl|=0.97±0.12 is compatible with unity.

    We report on a search for a heavy Majorana neutrino in the decays τ-→π-νh, νh→π± =e, μ. The results are obtained using the full data sample of 988 fb-1 collected with the Belle detector at the KEKB asymmetric energy e+e- collider, which contains 912×106 ττ pairs. We observe no significant signal and set 95% CL upper limits on the couplings of the heavy right-handed neutrinos to the conventional standard model left-handed neutrinos in the mass range 0.2-1.6 GeV/c2. This is the first study of a mixed couplings of heavy neutrinos to τ leptons and light-flavor leptons.

    We search for the B0→pς¯0π- decay with ς¯0→Λ¯γ, where the γ is not measured, using a data sample corresponding to an integrated luminosity of 711 fb-1 which contains 772×106 BB¯ pairs, collected around the ϒ(4S) resonance with the Belle detector at the KEKB asymmetric-energy e+e- collider. We measure for the first time the B0→pς¯0π- branching fraction to be B(B0→pς¯0π-)=(1.17-0.40+0.43(stat)±0.07(syst))×10-6 with a significance of 3.0σ. We simultaneously measure the branching fraction for the related channel B0→pΛ¯π- with much improved precision.

    We present a search for the lepton-flavor-violating decays Bs0 → ℓ∓ τ±, where ℓ = e, μ, using the full data sample of 121 fb−1 collected at the Υ(5S) resonance with the Belle detector at the KEKB asymmetric-energy e+ e− collider. We use Bs0B¯s0 events in which one Bs0 meson is reconstructed in a semileptonic decay mode and the other in the signal mode. We find no evidence for Bs0 → ℓ∓ τ± decays and set upper limits on their branching fractions at 90% confidence level as B (Bs0 → e∓ τ±) < 14 × 10−4 and B (Bs0 → μ∓ τ±) < 7.3 × 10−4. Our result represents the first upper limit on the Bs0 → e∓ τ± decay rate. [Figure not available: see fulltext.]

    Abstract

    We report the first measurement of the inclusive e<sup>+</sup>e<sup>−</sup>→$$ b\overline{b} $$→$$ {D}_s^{\pm } $$X and e<sup>+</sup>e<sup>−</sup>→$$ b\overline{b} $$→ D<sup>0</sup>/$$ {\overline{D } }^0 $$X cross sections in the energy range from 10.63 to 11.02 GeV. Based on these results, we determine σ(e<sup>+</sup>e<sup>−</sup>→$$ {B}_s^0{\overline{B } }_s^0 $$X) and σ(e<sup>+</sup>e<sup>−</sup>→$$ B\overline{B} $$X) in the same energy range. We measure the fraction of $$ {B}_s^0 $$ events at Υ(10860) to be f<sub>s</sub> = ($$ {22.0}_{-2.1}^{+2.0} $$)%. We determine also the ratio of the $$ {B}_s^0 $$ inclusive branching fractions $$ \mathcal{B} $$($$ {B}_s^0 $$→ D<sup>0</sup>/$$ {\overline{D } }^0 $$X)/$$ \mathcal{B} $$($$ {B}_s^0 $$→$$ {D}_s^{\pm } $$X) = 0.416 ± 0.018 ± 0.092. The results are obtained using the data collected with the Belle detector at the KEKB asymmetric-energy e<sup>+</sup>e<sup>−</sup> collider.

    Abstract

    We measure the cross section of e<sup>+</sup>e<sup>−</sup> → η<sub>c</sub>J/ψ at the Υ(nS)(n = 1–5) on-resonance and 10.52 GeV off-resonance energy points using the full data sample collected by the Belle detector with an integrated luminosity of 955 fb<sup>−1</sup>. We also search for double charmonium production in e<sup>+</sup>e<sup>−</sup> → η<sub>c</sub>J/ψ via initial state radiation near the η<sub>c</sub>J/ψ threshold. No evident signal of the double charmonium state is found, but evidence for the e<sup>+</sup>e<sup>−</sup>→ η<sub>c</sub>J/ψ process is found with a statistical significance greater than 3.3σ near the η<sub>c</sub>J/ψ threshold. The average cross section near the threshold is measured and upper limits of cross sections are set for other regions.

    We observe a narrow peaking structure in the pK- invariant-mass spectrum near the Λη threshold. The peak is clearly seen in 1.5 million events of Λc+→pK-π+ decay using the 980 fb-1 data sample collected by the Belle detector at the KEKB asymmetric-energy e+e- collider. We try two approaches to explain this structure: as a new resonance and as a cusp at the Λη threshold. The best fit is obtained with a coherent sum of a Flatté function and a constant background amplitude with the reduced χ2 of 257/243 (p=0.25), while the fits to Breit-Wigner functions are unfavored by more than 7σ. The best fit explains the structure as a cusp at the Λη threshold, and the obtained parameters are consistent with the known properties of Λ(1670). The observation gives the first identification of a threshold cusp in hadrons from the spectrum shape.

    We report the first measurement of the Michel parameter ζ′ in the τ-→μ-ν¯μντ decay with a new method proposed just recently. The measurement is based on the reconstruction of the τ-→μ-ν¯μντ events with subsequent muon decay in flight in the Belle central drift chamber. The analyzed data sample of 988 fb-1 collected by the Belle detector corresponds to approximately 912×106 τ+τ- pairs. We measure ζ′=0.22±0.94(stat)±0.42(syst), which is in agreement with the standard model prediction of ζ′=1. Statistical uncertainty dominates in this study, being a limiting factor, while systematic uncertainty is well under control. Our analysis proved the practicability of this promising method and its prospects for further precise measurement in future experiments.

    We present the first measurement of the Michel parameter ζ′ in the τ-→μ-ν¯μντ decay using the full data sample of 988 fb-1 collected by the Belle detector operating at the KEKB asymmetric energy e+e- collider. The method is based on the reconstruction of the μ-→e-ν¯eνμ decay-in-flight in the Belle central drift chamber and relies on the correlation between muon spin and its daughter electron momentum. We study the main sources of the background that can imitate the signal decay, such as kaon and pion decays-in-flight and charged particle scattering on the detector material. Highly efficient methods of their suppression are developed and applied to select 165 signal-candidate events. We obtain ζ′=0.22±0.94±0.42 where the first uncertainty is statistical, and the second one is systematic. The result is in agreement with the Standard Model prediction of ζ′=1.

    We present a measurement of the differential shapes of exclusive B→D∗ℓν¯ℓ (B=B-,B¯0 and ℓ=e, μ) decays with hadronic tag-side reconstruction for the full 711 fb-1 Belle dataset. We extract the Caprini-Lellouch-Neubert (CLN) and Boyd-Grinstein-Lebed (BGL) form factor parameters and use an external input for the absolute branching fractions to determine the Cabibbo-Kobayashi-Maskawa matrix element and find |Vcb|CLN=(40.2±0.9)×10-3 and |Vcb|BGL=(40.7±1.0)×10-3 with the zero-recoil lattice QCD point F(1)=0.906±0.013. We also perform a study of the impact of beyond zero-recoil lattice QCD calculations on the |Vcb| determinations. Additionally, we present the lepton-flavor universality ratio Reμ=B(B→D∗eν¯e)/B(B→D∗μν¯μ)=0.993±0.023±0.023, the electron and muon forward-backward asymmetry and their difference ΔAFB=0.028±0.028±0.008, and the electron and muon D∗ longitudinal polarization fraction and their difference ΔFLD∗=0.030±0.025±0.007. The uncertainties quoted correspond to the statistical and systematic uncertainties, respectively.

    Charged-lepton-flavor-violation is predicted in several new physics scenarios. We update the analysis of τ lepton decays into a light charged lepton (ℓ = e ± or μ ±) and a vector meson (V 0 = ρ 0, ϕ, ω, K *0, or K¯ *0) using 980 fb−1 of data collected with the Belle detector at the KEKB collider. No significant excess of such signal events is observed, and thus 90% credibility level upper limits are set on the τ → ℓV 0 branching fractions in the range of (1.7–4.3) × 10−8. These limits are improved by 30% on average from the previous results. [Figure not available: see fulltext.].

    We study B+→π+π0π0 using 711 fb-1 of data collected at the ϒ(4S) resonance with the Belle detector at the KEKB asymmetric-energy e+e- collider. We measure an inclusive branching fraction of (19.0±1.5±1.4)×10-6 and an inclusive CP asymmetry of (9.2±6.8±0.7)%, where the first uncertainties are statistical and the second are systematic, and a B+→ρ(770)+π0 branching fraction of (11.2±1.1±0.9-1.6+0.8)×10-6, where the third uncertainty is due to possible interference with B+→ρ(1450)+π0. We present the first observation of a structure around 1 GeV/c2 in the π0π0 mass spectrum, with a significance of 6.4σ, and measure a branching fraction to be (6.9±0.9±0.6)×10-6. We also report a measurement of local CP asymmetry in this structure.

    We report measurements of the ratios of branching fractions for B→D¯(∗)πℓ+νℓ and B→D¯(∗)π+π-ℓ+νℓ relative to B→D¯∗ℓ+νℓ decays with ℓ=e, μ. These results are obtained from a data sample that contains 772×106BB¯ pairs collected near the ϒ(4S) resonance with the Belle detector at the KEKB asymmetric energy e+e- collider. Fully reconstructing both B mesons in the event, we obtain B(B0→D¯0π-ℓ+νℓ)B(B0→D∗-ℓ+νℓ)=(7.23±0.36±0.14)%, B(B+→D-π+ℓ+νℓ)B(B+→D¯∗0ℓ+νℓ)=(6.78±0.24±0.18)%, B(B0→D¯∗0π-ℓ+νℓ)B(B0→D∗-ℓ+νℓ)=(11.10±0.48±0.23)%, B(B+→D∗-π+ℓ+νℓ)B(B+→D¯∗0ℓ+νℓ)=(9.50±0.33±0.34)%, B(B0→D-π+π-ℓ+νℓ)B(B0→D∗-ℓ+νℓ)=(2.91±0.37±0.26)%, B(B+→D¯0π+π-ℓ+νℓ)B(B+→D¯∗0ℓ+νℓ)=(3.10±0.26±0.22)%, B(B0→D∗-π+π-ℓ+νℓ)B(B0→D∗-ℓ+νℓ)=(0.99±0.43±0.20)%, B(B+→D¯∗0π+π-ℓ+νℓ)B(B+→D¯∗0ℓ+νℓ)=(1.25±0.27±0.15)%, where the uncertainties are statistical and systematic, respectively. These are the most precise measurements of these branching fraction ratios to date. The invariant mass spectra of the Dπ, D∗π, and Dππ systems are studied, and the branching fraction products B(B0→D2∗-ℓ+νℓ)×B(D2∗-→D¯0π-)=(0.157±0.015±0.005)%, B(B+→D¯0∗0ℓ+νℓ)×B(D¯0∗0→D-π+)=(0.054±0.022±0.005)%, B(B+→D¯2∗0ℓ+νℓ)×B(D¯2∗0→D-π+)=(0.163±0.011±0.008)%, B(B0→D1-ℓ+νℓ)×B(D1-→D¯∗0π-)=(0.306±0.050±0.029)%, B(B0→D1′-ℓ+νℓ)×B(D1′-→D¯∗0π-)=(0.206±0.068±0.025)%, B(B0→D2∗-ℓ+νℓ)×B(D2∗-→D¯∗0π-)=(0.051±0.040±0.010)%, B(B+→D¯10ℓ+νℓ)×B(D¯10→D∗-π+)=(0.249±0.023±0.015)%, B(B+→D¯1′0ℓ+νℓ)×B(D¯1′0→D∗-π+)=(0.138±0.036±0.009)%, B(B+→D¯2∗0ℓ+νℓ)×B(D¯2∗0→D∗-π+)=(0.137±0.026±0.009)%, B(B0→D1-ℓ+νℓ)×B(D1-→D-π+π-)=(0.102±0.013±0.009)%, B(B+→D¯10ℓ+νℓ)×B(D¯10→D¯0π+π-)=(0.105±0.011±0.009)%, are extracted.

    Using the data sample of 980 fb-1 collected with the Belle detector operating at the KEKB asymmetric-energy e+e- collider, we present the results of an investigation of the Λπ+ and Λπ- invariant mass distributions looking for substructure in the decay Λc+→Λπ+π+π-. We find a significant signal in each mass distribution. When interpreted as resonances, we find for the Λπ+ (Λπ-) combination a mass of 1434.3±0.6(stat)±0.9(syst) MeV/c2 [1438.5±0.9(stat)±2.5(syst) MeV/c2], an intrinsic width of 11.5±2.8(stat)±5.3(syst) MeV/c2 [33.0±7.5(stat)±23.6(syst) MeV/c2] with a significance of 7.5σ (6.2σ). As these two signals are very close to the K̄N threshold, we also investigate the possibility of a K̄N cusp, and find that we cannot discriminate between these two interpretations due to the limited size of the data sample.

    We report a study of Λc+→Λh+ and Λc+→Σ0h+ (h=K,π) decays based on a data sample of 980fb-1 collected with the Belle detector at the KEKB energy-asymmetric e+e- collider. The first results of direct CP asymmetry in two-body singly Cabibbo-suppressed (SCS) decays of charmed baryons are measured, ACPdir(Λc+→ΛK+)=+0.021±0.026±0.001 and ACPdir(Λc+→Σ0K+)=+0.025±0.054±0.004. We also make the most precise measurement of the decay asymmetry parameters (α) for the four modes of interest and search for CP violation via the α-induced CP asymmetry (ACPα). We measure ACPα(Λc+→ΛK+)=-0.023±0.086±0.071 and ACPα(Λc+→Σ0K+)=+0.08±0.35±0.14, which are the first ACPα results for SCS decays of charmed baryons. We search for Λ-hyperon CP violation in Λc+→(Λ,Σ0)π+ and find ACPα(Λ→pπ-)=+0.013±0.007±0.011. This is the first time that hyperon CP violation has been measured via Cabibbo-favored charm decays. No evidence of baryon CP violation is found. We also obtain the most precise branching fractions for two SCS Λc+ decays, B(Λc+→ΛK+)=(6.57±0.17±0.11±0.35)×10-4 and B(Λc+→Σ0K+)=(3.58±0.19±0.06±0.19)×10-4. The first uncertainties are statistical and the second systematic, while the third uncertainties come from the uncertainties on the world average branching fractions of Λc+→(Λ,Σ0)π+.

    Abstract

    We present the analysis of two-particle angular correlations using coordinate systems defined with the conventional beam axis and the event thrust axis. We propose the latter as a good representation for the correlation structure interpretation in the e<sup>+</sup>e<sup>−</sup> collision system. The e<sup>+</sup>e<sup>−</sup> collisions to hadronic final states at center-of-mass energies of $$ \sqrt{s} $$ = 10.52 GeV and 10.58 GeV are recorded by the Belle detector at KEKB. In this paper, results on the first dataset are supplementary to the previous Belle publication [1]. At the same time, the latter is the first two-particle correlation measurement at collision energy on the Υ(4S) resonance and is sensitive to its decay products. Measurements are reported as a function of the charged-particle multiplicity. Finally, a qualitative understanding of the correlation structure is discussed using a combination of Monte Carlo simulations and experimental data.

    We present a search for the decay X(3872)→π+π-π0 in the (772±11)×106 ϒ(4S)→BB¯ data sample collected at the Belle detector, where the X(3872) is produced in B±→K±X(3872) and B0→KS0X(3872) decays. We do not observe a signal, and set 90% credible upper limits for two different models of the decay processes: if the decay products are distributed uniformly in phase space, B(X(3872)→π+π-π0)<1.3%, and if M(π+π-) is concentrated near the mass of the D0D¯0 pair in the process X(3872)→D0D¯∗0+c.c.→D0D¯0π0→π+π-π0, B(X(3872)→π+π-π0)<1.2×10-3.

    We study the decay B+→K+K-π+ and investigate the angular distribution of K+K- pairs with invariant mass below 1.1 GeV/c2. This region exhibits both a strong enhancement in signal and very large direct CP violation. We construct a coherent sum model for the angular distribution of the S- and P-wave, and report the ratio of their amplitudes, the relative phase and the forward-backward asymmetry. We also report absolute differential branching fractions and direct CP asymmetry for the decay in bins of MK+K- and the differential branching fractions in bins of MK+π-. The results are based on a data sample that contains 772×106 BB¯ pairs collected at the ϒ(4S) resonance with the Belle detector at the KEKB asymmetric-energy e+e- collider. The result favors the presence of S- and D-waves in low MK+K- region to the detriment of a P-wave.

    We measure the ratio of branching fractions for the ϒ(4S) decays to B+B- and B0B¯0 using B+→J/ψ(ℓℓ)K+ and B0→J/ψ(ℓℓ)K0 samples, where J/ψ(ℓℓ) stands for J/ψ→ℓ+ℓ- (ℓ=e or μ), with 711 fb-1 of data collected at the ϒ(4S) resonance with the Belle detector. We find the decay rate ratio of ϒ(4S)→B+B- over ϒ(4S)→B0B¯0 to be 1.065±0.012±0.019±0.047, which is the most precise measurement to date. The first and second uncertainties are statistical and systematic, respectively, and the third uncertainty is due to the assumption of isospin symmetry in B→J/ψ(ℓℓ)K.

    We present a study of rare decay modes B+→Ds+h0, B+→Ds∗+h0, and B+→D+h0, where h0 denotes the neutral meson η or K0, using a data sample of (772±10)×106 BB¯ events produced at the ϒ(4S) resonance. The data were collected by the Belle detector operating at the asymmetric-energy KEKB collider. We find no evidence for these decays, so we set upper limits at the 90% confidence level on the branching fractions of B+→Ds+h0, Ds∗+h0, and D+h0 decay modes. Along with these rare decay modes, we report improved measurements of the color-suppressed decay branching fractions B(B¯0→D0η)=(26.6±1.2±2.1)×10-5 and B(B¯0→D0K̄0)=(5.6±0.5±0.2)×10-5. The first and second quoted uncertainties are statistical and systematic, respectively.

    We present measurements of the branching fractions for the singly Cabibbo-suppressed decays D+→K+K-π+π0 and Ds+→K+π-π+π0, and the doubly Cabibbo-suppressed decay D+→K+π-π+π0, based on 980 fb-1 of data recorded by the Belle experiment at the KEKB e+e- collider. We measure these modes relative to the Cabibbo-favored modes D+→K-π+π+π0 and Ds+→K+K-π+π0. Our results for the ratios of branching fractions are B(D+→K+K-π+π0)/B(D+→K-π+π+π0)=(11.32±0.13±0.26)%, B(D+→K+π-π+π0)/B(D+→K-π+π+π0)=(1.68±0.11±0.03)%, and B(Ds+→K+π-π+π0)/B(Ds+→K+K-π+π0)=(17.13±0.62±0.51)%, where the uncertainties are statistical and systematic, respectively. The second value corresponds to (5.83±0.42)×tan4θC, where θC is the Cabibbo angle; this value is larger than other measured ratios of branching fractions for a doubly Cabibbo-suppressed charm decay to a Cabibbo-favored decay. Multiplying these results by world average values for B(D+→K-π+π+π0) and B(Ds+→K+K-π+π0) yields B(D+→K+K-π+π0)=(7.08±0.08±0.16±0.20)×10-3, B(D+→K+π-π+π0)=(1.05±0.07±0.02±0.03)×10-3, and B(Ds+→K+π-π+π0)=(9.44±0.34±0.28±0.32)×10-3, where the third uncertainty is due to the branching fraction of the normalization mode. The first two results are consistent with, but more precise than, the current world averages. The last result is the first measurement of this branching fraction.

    We report a study of Λc+→ς+π0, Λc+→ς+η, and Λc+→ς+η′ using the data sample corresponding to an integrated luminosity of 980 fb-1 collected with the Belle detector at the KEKB asymmetric-energy e+e- collider. The branching fractions relative to Λc+→ς+π0 are measured as BΛc+→ς+η/BΛc+→ς+π0=0.25±0.03±0.01 and BΛc+→ς+η′/BΛc+→ς+π0=0.33±0.06±0.02. Using BΛc+→ς+π0=(1.25±0.10)%, we obtain BΛc+→ς+η=(3.14±0.35±0.17±0.25)×10-3 and BΛc+→ς+η′=(4.16±0.75±0.25±0.33)×10-3. Here the uncertainties are statistical, systematic, and from BΛc+→ς+π0, respectively. The ratio of the branching fraction of Λc+→ς+η′ with respect to that of Λc+→ς+η is measured to be BΛc+→ς+η′/BΛc+→ς+η=1.34±0.28±0.08. We update the asymmetry parameter of Λc+→ς+π0, ας+π0=-0.48±0.02±0.02, with a considerably improved precision. The asymmetry parameters of Λc+→ς+η and Λc+→ς+η′ are measured to be ας+η=-0.99±0.03±0.05 and ας+η′=-0.46±0.06±0.03 for the first time.

    An absolute measurement of the A+c lifetime is reported using A+c -> pK-pi+ decays in events reconstructed from data collected by the Belle II experiment at the SuperKEKB asymmetric-energy electron-positron collider. The total integrated luminosity of the data sample, which was collected at center-of-mass energies at or near the (sic)(4S) resonance, is 207.2 fb(-1). The result, tau(Lambda(+)(c)) = 203.20 10.89 10.77 fs, where the first uncertainty is statistical and the second systematic, is the most precise measurement to date and is consistent with previous determinations.

    We report the measurement of the two-photon decay width of χc2(1P) in two-photon processes at the Belle experiment. We analyze the process γγ → χc2(1P) → J/ψγ, J/ψ → ℓ+ℓ− (ℓ = e or μ) using a data sample of 971 fb−1 collected with the Belle detector at the KEKB e+e− collider. In this analysis, the product of the two-photon decay width of χc2(1P) and the branching fraction is determined to be Γγγ(χc2(1P))B(χc2(1P)→J/ψγ)B(J/ψ→ℓ+ℓ−)=14.8±0.3(stat.)±0.7(syst.) eV, which corresponds to Γγγ(χc2(1P)) = 653 ± 13(stat.) ± 31(syst.) ± 17(B.R.) eV, where the third uncertainty is from B(χc2(1P) → J/ψγ) and B(J/ψ → ℓ+ℓ−).

    We present the study of B[over ¯]^{0}→Σ_{c}(2455)^{0,++}π^{±}p[over ¯] decays based on 772×10^{6}  BB[over ¯] events collected with the Belle detector at the KEKB asymmetric-energy e^{+}e^{-} collider. The Σ_{c}(2455)^{0,++} candidates are reconstructed via their decay to Λ_{c}^{+}π^{∓} and Λ_{c}^{+} decays to pK^{-}π^{+}, pK_{S}^{0}, and Λπ^{+} final states. The corresponding branching fractions are measured to be B(B[over ¯]^{0}→Σ_{c}(2455)^{0}π^{+}p[over ¯])=(1.09±0.06±0.07)×10^{-4} and B(B[over ¯]^{0}→Σ_{c}(2455)^{++}π^{-}p[over ¯])=(1.84±0.11±0.12)×10^{-4}, which are consistent with the world average values with improved precision. A new structure is found in the M_{Σ_{c}(2455)^{0,++}π^{± } } spectrum with a significance of 4.2σ including systematic uncertainty. The structure is possibly an excited Λ_{c}^{+} and is tentatively named Λ_{c}(2910)^{+}. Its mass and width are measured to be (2913.8±5.6±3.8)  MeV/c^{2} and (51.8±20.0±18.8)  MeV, respectively. The products of branching fractions for the Λ_{c}(2910)^{+} are measured to be B(B[over ¯]^{0}→Λ_{c}(2910)^{+}p[over ¯])×B(Λ_{c}(2910)^{+}→Σ_{c}(2455)^{0}π^{+})=(9.5±3.6±1.6)×10^{-6} and B(B[over ¯]^{0}→Λ_{c}(2910)^{+}p[over ¯])×B(Λ_{c}(2910)^{+}→Σ_{c}(2455)^{++}π^{-})=(1.24±0.35±0.10)×10^{-5}. Here, the first and second uncertainties are statistical and systematic, respectively.

    Using 980 fb-1 of data collected on and around the (nS) (n=1, 2, 3, 4, 5) resonances with the Belle detector at the KEKB collider, we measure the cross section of e+e-→ηφ from threshold to 3.95 GeV via initial state radiation. There are clear φ(1680) and J/ψ signals but no significant φ(2170) signal in the ηφ final state. The branching fraction B[J/ψ→ηφ] is measured to be (7.2±0.8±0.5)×10-4. The resonant parameters of φ(1680) are determined to be mφ(1680)=(1696±8±10) MeV/c2 (statistical and systematic errors, respectively), Γφ(1680)=(175±13±16) MeV and, depending on the possible presence of predominantly constructive or destructive interference between φ(1680) and continuum production, Γφ(1680)e+e-·B[φ(1680)→ηφ] and B[φ(1680)→ηφ] are determined to be (75±10±11) eV and (25±12±2)% or (207±16±20) eV and (23±10±2)%, respectively. The upper limit for Γφ(2170)e+e-·B[φ(2170)→ηφ] is determined to be either 0.17 or 18.6 eV at the 90% confidence level.

    Using (771.6±10.6)×106 BB¯ meson pairs recorded by the Belle experiment at the KEKB e+e- collider, we report the branching fractions B(B¯0→D∗+π-)=(2.62±0.02±0.09)×10-3 and B(B¯0→D∗+K-)=(2.22±0.06±0.08)×10-4; the quoted uncertainties are statistical and systematic, respectively. A measurement of the ratio of these branching fractions is also presented, RK/π=B(B¯→D∗+K-)/B(B¯→D∗+π-)=(8.41±0.24±0.13)×10-2, where systematic uncertainties due to the D∗+ meson reconstruction cancel out. Furthermore, we report a new QCD factorization test based on the measured ratios for B¯→D∗+h- and B¯→D∗+ℓ-ν decays at squared momentum transfer values equivalent to the mass of the h=π or K hadron. The parameters |a1(h)| are measured to be |a1(π)|=0.884±0.004±0.003±0.016 and |a1(K)|=0.913±0.019±0.008±0.013, where the last uncertainties account for all external inputs. These values are approximately 15% lower than those expected from theoretical predictions. Subsequently, flavor SU(3) symmetry is tested by measuring the ratios for pions and kaons, |a1(K)|2/|a1(π)|2=1.066±0.042±0.018±0.023, as well as for different particle species. The ratio is consistent with unity and therefore no evidence for SU(3) symmetry breaking effects is found at the 5% precision level.

    We search for a new gauge boson Z′ that couples only to heavy leptons and their corresponding neutrinos in the process e+e-→Z′(→μ+μ-)μ+μ-, using a 643 fb-1 data sample collected by the Belle experiment at or near the ϒ(1S,2S,3S,4S,5S) resonances at the KEKB collider. While previous searches for Z′ performed a data-based estimation of the initial state radiation effect, our search for the Z′ is the first to include effects due to initial state radiation in the signal simulated samples that were used in estimating the detection efficiency. No signal is observed in the Z′ mass range of 0.212-10 GeV/c2, and we set an upper limit on the coupling strength, g′, constraining the possible Z′ contribution to the anomalous magnetic dipole moment of the muon.

    Using 980 fb-1 of data at and around the I (nS) (n=1, 2, 3, 4, 5) resonances collected with the Belle detector at the KEKB asymmetric-energy e+e-collider, the two-photon process γγ→γψ(2S) is studied from the threshold to 4.2 GeV for the first time. Two structures are seen in the invariant mass distribution of γψ(2S): one at MR1=3922.4±6.5±2.0 MeV/c2 with a width of ΓR1=22±17±4 MeV, and another at MR2=4014.3±4.0±1.5 MeV/c2 with a width of ΓR2=4±11±6 MeV; the signals are parametrized with the incoherent sum of two Breit-Wigner functions. The first structure is consistent with the X(3915) or the χc2(3930), and the local statistical significance is determined to be 3.1σ with the systematic uncertainties included. The second matches none of the known charmonium or charmoniumlike states, and its global significance is determined to be 2.8σ including the look-elsewhere effect. The production rates are ΓγγB(R1→γψ(2S))=9.8±3.6±1.3 eV assuming (JPC,|λ|)=(0++,0) or 2.0±0.7±0.2 eV with (2++,2) for the first structure and ΓγγB(R2→γψ(2S))=6.2±2.2±0.8 eV with (0++,0) or 1.2±0.4±0.2 eV with (2++,2) for the second. Here, the first errors are statistical and the second systematic, and λ is the helicity.

    We present the first observation of the ωc0→ω-μ+νμ decay and present measurements of the branching fraction ratios of the ωc0→ω-ℓ+νℓ decays compared to the reference mode ωc0→ω-π+, (ℓ=e or μ). This analysis is based on 89.5 fb-1, 711 fb-1, and 121.1 fb-1 data samples collected with the Belle detector at the KEKB asymmetric-energy e+e- collider at the center-of-mass energies of 10.52 GeV, 10.58 GeV, and 10.86 GeV, respectively. The ωc0 signal yields are extracted by fitting Mωℓ and Mωπ spectra. The branching fraction ratios B(ωc0→ω-e+νe)/B(ωc0→ω-π+) and B(ωc0→ω-μ+νμ)/B(ωc0→ω-π+) are measured to be 1.98±0.13(stat)±0.08(syst) and 1.94±0.18(stat)±0.10(syst), respectively. The ratio of B(ωc0→ω-e+νe)/B(ωc0→ω-μ+νμ) is measured to be 1.02±0.10(stat)±0.02(syst), which is consistent with the expectation of lepton flavor universality.

    The measurement of two-particle angular correlation functions in high-multiplicity e+e-collisions at s=10.52 GeV is reported. In this study, the 89.5 fb-1 of hadronic e+e-annihilation data collected by the Belle detector at KEKB are used. Two-particle angular correlation functions are measured in the full relative azimuthal angle (Δφ) and three units of pseudorapidity (Δη), defined by either the electron beam axis or the event-shape thrust axis, and are studied as a function of charged-particle multiplicity. The measurement in the thrust axis analysis, with mostly outgoing quark pairs determining the reference axis, is sensitive to the region of additional soft gluon emissions. No significant anisotropic collective behavior is observed with either coordinate analyses. Near-side jet correlations appear to be absent in the thrust axis analysis. The measurements are compared to predictions from various event generators and are expected to provide new constraints to the phenomenological models in the low-energy regime.

    Abstract

    We report a measurement of the electric dipole moment of the τ lepton (dτ) using an 833 fb<sup>−1</sup> data sample collected near the Υ(4S) resonance, with the Belle detector at the KEKB asymmetric-energy e<sup>+</sup>e<sup>−</sup> collider. Using an optimal observable method, we obtain the real and imaginary parts of d<sub>τ</sub> as Re(d<sub>τ</sub>) = (−0.62 ± 0.63) × 10<sup>−17</sup>ecm and Im(d<sub>τ</sub>) = (−0.40 ± 0.32) × 10<sup>−17</sup>ecm, respectively. These results are consistent with null electric dipole moment at the present level of experimental sensitivity and improve the sensitivity by about a factor of three.

    Abstract

    We present the first measurement of the branching fraction of the singly Cabibbo-suppressed (SCS) decay $$ {\Lambda}_c^{+} $$→ pη′ with η′ → ηπ<sup>+</sup>π<sup>−</sup>, using a data sample corresponding to an integrated luminosity of 981 fb<sup>−1</sup>, collected by the Belle detector at the KEKB e<sup>+</sup>e<sup>−</sup> asymmetric-energy collider. A significant $$ {\Lambda}_c^{+} $$→ pη′ signal is observed for the first time with a signal significance of 5.4σ. The relative branching fraction with respect to the normalization mode $$ {\Lambda}_c^{+} $$→ pK<sup>−</sup>π<sup>+</sup> is measured to be$$ \frac{\mathcal{B}\left({\Lambda}_c^{+}\to p\eta^{\prime}\right)}{\mathcal{B}\left({\Lambda}_c^{+}\to {pK}^{-}{\pi}^{+}\right)}=\left(7.54\pm 1.32\pm 0.73\right)\times {10}^{-3}, $$

    where the uncertainties are statistical and systematic, respectively. Using the world-average value of $$ \mathcal{B}\left({\Lambda}_c^{+}\to {pK}^{-}{\pi}^{+}\right) $$ = (6.28 ± 0.32) × 10<sup>−2</sup>, we obtain$$ \mathcal{B}\left({\Lambda}_c^{+}\to p\eta^{\prime}\right)=\left(4.73\pm 0.82\pm 0.46\pm 0.24\right)\times {10}^{-4}, $$

    where the uncertainties are statistical, systematic, and from $$ \mathcal{B}\left({\Lambda}_c^{+}\to {pK}^{-}{\pi}^{+}\right) $$, respectively.

    Hydraulic quantities governing the generation of bedforms (formed spontaneously on the bottoms of rivers) have been investigated through geomorphological methods, laboratory experiments, stability analyses, numerical analyses, and other research methods. Recently, numerical analysis has been conducted using fine spatial grids to accurately describe morphodynamics. However, numerical analysis cannot always describe the real phenomena, because it is based on assumptions. One effective way to verify physical assumptions is to compare numerical analysis with actual measurements of equivalent resolution. Measurement data with high resolution enable the construction of a duplicate of the measurement target on a computer called a “digital twin.” To construct a digital twin of the process of bedforms generation and development, geometries of the water surface and the bed surface must be simultaneously measured. We developed and verified a measurement method for the construction of a digital twin during the generation and development of bedforms. The measurement system uses two cameras and a line laser to simultaneously measure the water surface and bed surface. Accurate refraction correction at the water surface is possible by acquiring the shape of the water surface, allowing the bottom shape to be determined by geometric processing. The method provides sub-millimeter-accurate measurements of the water surface and bottom with a spatial resolution of 0.95 cm longitudinally and 0.038 cm transversely in a 12 m × 0.45 m flume and takes only 1 min per measurement. This method can provide measurement results that contribute to the understanding of the generation and development of bedforms.

    We search for a light Higgs boson (A0) decaying into a τ+τ- or μ+μ- pair in the radiative decays of ϒ(1S). The production of ϒ(1S) mesons is tagged by ϒ(2S)→π+π-ϒ(1S) transitions, using 158×106 ϒ(2S) events accumulated with the Belle detector at the KEKB asymmetric energy electron-positron collider. No significant A0 signals in the mass range from the τ+τ- or μ+μ- threshold to 9.2 GeV/c2 are observed. We set the upper limits at 90% credibility level (C.L.) on the product branching fractions for ϒ(1S)→γA0 and A0→τ+τ- varying from 3.8×10-6 to 1.5×10-4. Our results represent an approximately twofold improvement on the current world best upper limits for the ϒ(1S)→γA0(→τ+τ-) production. For A0→μ+μ-, the upper limits on the product branching fractions for ϒ(1S)→γA0 and A0→μ+μ- are at the same level as the world average limits, and vary from 3.1×10-7 to 1.6×10-5. The upper limits at 90% credibility level on the Yukawa coupling fϒ(1S) and mixing angle sinθA0 are also given.

    A search for double-heavy tetraquark state candidates Xccs¯s¯ decaying to Ds+Ds+ and Ds∗+Ds∗+ is presented for the first time using the data samples of 102×106 ϒ(1S) and 158×106 ϒ(2S) events, and the data samples at s=10.52, 10.58, and 10.867 GeV corresponding to integrated luminosities of 89.5, 711.0, and 121.4 fb-1, respectively, accumulated with the Belle detector at the KEKB asymmetric energy electron-positron collider. The invariant-mass spectra of the Ds+Ds+ and Ds∗+Ds∗+ are studied to search for possible resonances. No significant signals are observed, and the 90% confidence level upper limits on the product branching fractions [B(ϒ(1S,2S)→Xccs¯s¯+anything)×B(Xccs¯s¯→Ds+Ds+(Ds∗+Ds∗+))] in ϒ(1S,2S) inclusive decays and the product values of Born cross section and branching fraction [σ(e+e-→Xccs¯s¯+anything)×B(Xccs¯s¯→Ds+Ds+(Ds∗+Ds∗+))] in e+e- collisions at s=10.52, 10.58, and 10.867 GeV under different assumptions of Xccs¯s¯ masses and widths are obtained.

    We report results from a search for the decay B-s(0) -> eta eta using 121.4 fb(-1) of data collected at the Upsilon(5S) resonance with the Belle detector at the KEKB asymmetric-energy e(+)e(-) collider. We do not observe any signal and set an upper limit on the branching fraction of 14.3 x 10(-5) at 90% confidence level. This result represents a significant improvement over the previous most stringent limit.

    A search for the flavor-changing neutral-current decay B^{+}→K^{+}νν[over ¯] is performed at the Belle II experiment at the SuperKEKB asymmetric energy electron-positron collider. The data sample corresponds to an integrated luminosity of 63  fb^{-1} collected at the ϒ(4S) resonance and a sample of 9  fb^{-1} collected at an energy 60 MeV below the resonance. Because the measurable decay signature involves only a single charged kaon, a novel measurement approach is used that exploits not only the properties of the B^{+}→K^{+}νν[over ¯] decay, but also the inclusive properties of the other B meson in the ϒ(4S)→BB[over ¯] event, to suppress the background from other B meson decays and light-quark pair production. This inclusive tagging approach offers a higher signal efficiency compared to previous searches. No significant signal is observed. An upper limit on the branching fraction of B^{+}→K^{+}νν[over ¯] of 4.1×10^{-5} is set at the 90% confidence level.

    Abstract

    Charged lepton flavor violation is forbidden in the Standard Model but possible in several new physics scenarios. In many of these models, the radiative decays τ<sup>±</sup> → ℓ<sup>±</sup>γ (ℓ = e, μ) are predicted to have a sizeable probability, making them particularly interesting channels to search at various experiments. An updated search via τ<sup>±</sup> → ℓ<sup>±</sup>γ using full data of the Belle experiment, corresponding to an integrated luminosity of 988 fb<sup>−1</sup>, is reported for charged lepton flavor violation. No significant excess over background predictions from the Standard Model is observed, and the upper limits on the branching fractions, $$ \mathcal{B} $$(τ<sup>±</sup> → μ<sup>±</sup>γ) ≤ 4.2 × 10<sup>−8</sup> and $$ \mathcal{B} $$(τ<sup>±</sup> → e<sup>±</sup>γ) ≤ 5.6 × 10<sup>−8</sup>, are set at 90% confidence level.

    Using 980.6 fb(-1) of data collected with the Belle detector operating at the KEKB asymmetric-energy e(+)e(-), we present a measurement of the branching fraction of the singly Cabibbo-suppressed decay Lambda(+)(c) -> p omega. A clear Lambda(+)(c) signal is observed for Lambda(+)(c) -> p omega with a statistical significance of 9.1 standard deviations, and we measure the ratio of branching fractions B(Lambda(+)(c) -> p omega)/Bo(Lambda(+)(c) -> p omega)/B(Lambda(+)(c) -> pK(-)pi(+)) = (1.32 +/- 0.12(stat) +/- 0.10(syst)) x 10(-2), from which we infer the branching fraction, B(Lambda(+)(c) -> p omega) = (8.27 +/- 0.75(stat) +/- 0.62(syst) +/- 0.42(ref) x 10(-4). The first quoted uncertainty is statistical, the second systematic, and the third from the reference mode Lambda(+)(c) -> pK(-) pi(+).

    Using data samples of 89.5 and 711  fb^{-1} recorded at energies of sqrt[s]=10.52 and 10.58 GeV, respectively, with the Belle detector at the KEKB e^{+}e^{-} collider, we report measurements of branching fractions of semileptonic decays Ξ_{c}^{0}→Ξ^{-}ℓ^{+}ν_{ℓ} (ℓ=e or μ) and the CP-asymmetry parameter of Ξ_{c}^{0}→Ξ^{-}π^{+} decay. The branching fractions are measured to be B(Ξ_{c}^{0}→Ξ^{-}e^{+}ν_{e})=(1.31±0.04±0.07±0.38)% and B(Ξ_{c}^{0}→Ξ^{-}μ^{+}ν_{μ})=(1.27±0.06±0.10±0.37)%, and the decay parameter α_{Ξπ} is measured to be 0.63±0.03±0.01 with much improved precision compared with the current world average. The corresponding ratio B(Ξ_{c}^{0}→Ξ^{-}e^{+}ν_{e})/B(Ξ_{c}^{0}→Ξ^{-}μ^{+}ν_{μ}) is 1.03±0.05±0.07, which is consistent with the expectation of lepton flavor universality. The first measured asymmetry parameter A_{CP}=(α_{Ξ^{-}π^{+ } }+α_{Ξ[over ¯]^{+}π^{- } })/(α_{Ξ^{-}π^{+ } }-α_{Ξ[over ¯]^{+}π^{- } })=0.024±0.052±0.014 is found to be consistent with zero. The first and the second uncertainties above are statistical and systematic, respectively, while the third ones arise due to the uncertainty of the Ξ_{c}^{0}→Ξ^{-}π^{+} branching fraction.

    Abstract

    We measure the branching fractions and CP asymmetries for the singly Cabibbo-suppressed decays D<sup>0</sup> → π<sup>+</sup>π<sup>−</sup>η, D<sup>0</sup> → K<sup>+</sup>K<sup>−</sup>η, and D<sup>0</sup> → ϕη, using 980 fb<sup>−1</sup> of data from the Belle experiment at the KEKB e<sup>+</sup>e<sup>−</sup> collider. We obtain$$ {\displaystyle \begin{array}{c}\mathcal{B}\left({D}^0\to {\pi}^{+}{\pi}^{-}\eta \right)=\left[1.22\pm 0.02\left(\mathrm{stat}\right)\pm 0.02\left(\mathrm{syst}\right)\pm 0.03\left({\mathcal{B } }_{\mathrm{ref } }\right)\right]\times {10}^{-3},\\ {}\mathcal{B}\left({D}^0\to {K}^{+}{K}^{-}\eta \right)=\left[{1.80}_{-0.06}^{+0.07}\left(\mathrm{stat}\right)\pm 0.04\left(\mathrm{syst}\right)\pm 0.05\left({\mathcal{B } }_{\mathrm{ref } }\right)\right]\times {10}^{-4},\\ {}\mathcal{B}\left({D}^0\to \phi \eta \right)=\left[1.84\pm 0.09\left(\mathrm{stat}\right)\pm 0.06\left(\mathrm{syst}\right)\pm 0.05\left({\mathcal{B } }_{\mathrm{ref } }\right)\right]\times {10}^{-4},\end{array } } $$

    where the third uncertainty ($$ \mathcal{B} $$<sub>ref</sub>) is from the uncertainty in the branching fraction of the reference mode D<sup>0</sup> → K<sup>−</sup>π<sup>+</sup>η. The color-suppressed decay D<sup>0</sup> → ϕη is observed for the first time, with very high significance. The results for the CP asymmetries are$$ {\displaystyle \begin{array}{c}{A}_{CP}\left({D}^0\ {\pi}^{+}{\pi}^{-}\eta \right)=\left[0.9\pm 1.2\left(\mathrm{stat}\right)\pm 0.5\left(\mathrm{syst}\right)\right]\%,\\ {}{A}_{CP}\left({D}^0\to {K}^{+}{K}^{-}\eta \right)=\left[-1.4\pm 3.3\left(\mathrm{stat}\right)\pm 1.1\left(\mathrm{syst}\right)\right]\%,\\ {} ACP\ \left({D}^0\to \phi \eta \right)=\left[-1.9\pm 4.4\left(\mathrm{stat}\right)\pm 0.6\left(\mathrm{syst}\right)\right]\%.\end{array } } $$

    The results for D<sup>0</sup> → π<sup>+</sup>π<sup>−</sup>η are a significant improvement over previous results. The branching fraction and A<sub>CP</sub> results for D<sup>0</sup> → K<sup>+</sup>K<sup>−</sup>η, and the ACP result for D<sup>0</sup> → ϕη, are the first such measurements. No evidence for CP violation is found in any of these decays.

    We present measurements of partial branching fractions of inclusive semileptonic B→Xuℓ+νℓ decays using the full Belle dataset of 711 fb-1 of integrated luminosity at the ϒ(4S) resonance and for ℓ=e, μ. Inclusive semileptonic B→Xuℓ+νℓ decays are Cabibbo-Kobayashi-Maskawa (CKM) suppressed and measurements are complicated by the large background from CKM favored B→Xcℓ+νℓ transitions, which have a similar signature. Using machine learning techniques, we reduce this and other backgrounds effectively, while retaining access to a large fraction of the B→Xuℓ+νℓ phase space and high signal efficiency. We measure partial branching fractions in three phase-space regions covering about 31% to 86% of the accessible B→Xuℓ+νℓ phase space. The most inclusive measurement corresponds to the phase space with lepton energies of EℓB>1 GeV, and we obtain ΔB(B→Xuℓ+νℓ)=(1.59±0.07±0.16)×10-3 from a two-dimensional fit of the hadronic mass spectrum and the four-momentum-transfer squared distribution, with the uncertainties denoting the statistical and systematic error. We find |Vub|=(4.10±0.09±0.22±0.15)×10-3 from an average of four calculations for the partial decay rate with the third uncertainty denoting the average theory error. This value is higher but compatible with the determination from exclusive semileptonic decays within 1.3 standard deviations. In addition, we report charmless inclusive partial branching fractions separately for B+ and B0 mesons as well as for electron and muon final states. No isospin breaking or lepton flavor universality violating effects are observed.

    We present an analysis of the exclusive B+→π+π-ℓ+νℓ decay, where ℓ represents an electron or a muon, with the assumption of charge-conjugation symmetry and lepton universality. The study exploits the full ϒ(4S) data sample collected by the Belle detector, corresponding to 711 fb-1 of integrated luminosity. Events are selected by fully reconstructing one B meson in hadronic decay modes, subsequently determining the properties of the other B meson. We extract the signal yields using a binned maximum-likelihood fit to the missing-mass squared distribution in bins of the invariant mass of the two pions or the momentum transfer squared. We measure a total branching fraction of B(B+→π+π-ℓ+νℓ)=[22.7-1.6+1.9(stat)±3.5(syst)]×10-5, where the uncertainties are statistical and systematic, respectively. This result is the first reported measurement of this decay.

    We report results from a study of the spin and parity of Ξc(2970)+ using a 980 fb-1 data sample collected by the Belle detector at the KEKB asymmetric-energy e+e- collider. The decay angle distributions in the chain Ξc(2970)+→Ξc(2645)0π+→Ξc+π-π+ are analyzed to determine the spin of this charmed-strange baryon. The angular distributions strongly favor the Ξc(2970)+ spin J=1/2 over 3/2 or 5/2, under an assumption that the lowest partial wave dominates in the decay. We also measure the ratio of Ξc(2970)+ decay branching fractions R=B[Ξc(2970)+→Ξc(2645)0π+]/B[Ξc(2970)+→Ξc′0π+]=1.67±0.29(stat)-0.09+0.15(syst)±0.25(IS), where the last uncertainty is due to possible isospin-symmetry-breaking effects. This R value favors the spin-parity JP=1/2+ with the spin of the light-quark degrees of freedom sl=0. This is the first determination of the spin and parity of a charmed-strange baryon.

    Using the entire data sample of 980 fb-1 integrated luminosity collected with the Belle detector at the KEKB asymmetric-energy e+e- collider, we present an amplitude analysis measuring the branching fractions of the Cabibbo-allowed, W-exchange resonant decay Ξc0→Ξ0φ(→K+K-) with a polarized φ and the nonresonant decay via a direct process Ξc0→Ξ0K+K-. We present these measurements, relative to the normalization mode Ξ-π+, and find branching ratios B(Ξc0→Ξ0φ(→K+K-))(BΞc0→Ξ-π+)=0.036±0.004(stat.)±0.002(syst.) and B(Ξc0→Ξ0K+K-)B(Ξc0→Ξ-π+)=0.039±0.004(stat.)±0.002(syst.), which suggest that only minor cusping peaks occur in the combinatorial background of ω∗-→Ξ0K- due to these Ξc0 decays.

    We report the first measurement of the exclusive cross sections e+e− → BB¯ , e+e− → BB¯ ∗, and e+e− → B∗B¯ ∗ in the energy range from 10.63 GeV to 11.02 GeV. The B mesons are fully reconstructed in a large number of hadronic final states and the three channels are identified using a beam-constrained-mass variable. The shapes of the exclusive cross sections show oscillatory behavior with several maxima and minima. The results are obtained using data collected by the Belle experiment at the KEKB asymmetric-energy e+e− collider. [Figure not available: see fulltext.]

    Using a data sample of 980 fb−1 collected with the Belle detector at the KEKB asymmetric-energy e+e− collider, we study the processes of Ξc0→ΛK¯∗0, Ξc0→Σ0K¯∗0, and Ξc0→Σ+K∗− for the first time. The relative branching ratios to the normalization mode of Ξc0→Ξ−π+ are measured to beB(Ξc0→ΛK¯∗0)/B(Ξc0→Ξ−π+)=0.18±0.02(stat.)±0.01(syst.),B(Ξc0→Σ0K¯∗0)/B(Ξc0→Ξ−π+)=0.69±0.03(stat.)±0.03(syst.),B(Ξc0→Σ+K∗−)/B(Ξc0→Ξ−π+)=0.34±0.06(stat.)±0.02(syst.), where the uncertainties are statistical and systematic, respectively.

The asymmetry parameters α(Ξc0→ΛK¯∗0) and α(Ξc0→Σ+K∗−) are 0.15 ± 0.22(stat.) ± 0.04(syst.) and −0.52 ± 0.30(stat.) ± 0.02(syst.), respectively, where the uncertainties are statistical followed by systematic.

    We present a measurement of R-K(*), the branching fraction ratio B(B -> K* mu(+)mu(-))/B(B -> K* e(+) e(-)), for both charged and neutral B mesons. The ratio for the charged case RK*+ is the first measurement ever performed. In addition, we report absolute branching fractions for the individual modes in bins of the squared dilepton invariant mass q(2). The analysis is based on a data sample of 711 fb(-1), containing 772 x 10(6) B (B) over bar events, recorded at the Upsilon(4S) resonance with the Belle detector at the KEKB asymmetric-energy e(+)e(-) collider. The obtained results are consistent with standard model expectations.

    There was an error in the calculation of the value of NB0 in the original transcript. The value of f00 was erroneously set to 0.500 in the code (the value used in Monte Carlo studies), not the world average value of 0.486 as specified in the transcript. The effect of this change is to increase the quoted values of F(1)|Vcb|?EW by 1.4% and the branching fraction by 2.9%. The associated relative systematic uncertainties remain unchanged from the original transcript. Below, we report on the resulting changes in the measurement. The fit results from the Caprini-Lellouch-Neubert (CLN) and Boyd, Grinstein and Lebed (BGL) parameterizations are given in Tables I and II, respectively. (Table Presented).

    We present a search for the dark photon A in the B-0 -> A ' A ' decays, where A ' subsequently decays to e(+)e(-), mu(+)mu(-), and pi(+)pi(-). The search is performed by analyzing 772 x 10(6) B (B) over bar events collected by the Belle detector at the KEKB e(+)e(-) energy-asymmetric collider at the Upsilon(4S) resonance. No signal is found in the dark photon mass range 0.01 GeV/c(2) <= m(A ') <= 2.62 GeV/c(2), and we set upper limits of the branching fraction of B-0 -> A ' A ' at the 90% confidence level. The products of branching fractions, B(B-0 -> A ' A ) x B(A '-> e(+)e(-))(2) and B(B-0 -> A ' A ') x B(A '-> mu(+)mu(-))(2), have limits of the order of 10(-8) depending on the A ' mass. Furthermore, considering A ' decay rate to each pair of charged particles, the upper limits of B(B-0 -> A ' A '), we obtain the Higgs portal coupling for each assumed dark photon and dark Higgs mass. The Higgs portal couplings are of the order of 10(-2)-10(-1) at m(h ') similar or equal to m(B0) +/- 40 MeV/c(2) and 10(-1)-1 at mh ' similar or equal to m(B0) +/- 3 GeV/c(2).

    We report the first evidence for X(3872) production in two-photon interactions by tagging either the electron or the positron in the final state, exploring the highly virtual photon region. The search is performed in e+e-→e+e-J/ψ π+ π-, using 825 fb-1 of data collected by the Belle detector operated at the KEKB e+e-collider. We observe three X(3872) candidates, where the expected background is 0.11±0.10 events, with a significance of 3.2σ. We obtain an estimated value for γB(X(3872)→J/ψ π+ π-) assuming the Q2 dependence predicted by a cc meson model, where-Q2 is the invariant mass squared of the virtual photon. No X(3915)→J/ψ π+ π-candidates are found.

    We report branching fraction measurements of four decay modes of the Λc+ baryon, each of which includes an η meson and a Λ baryon in the final state, and all of which are measured relative to the Λc+→pK-π+ decay mode. The results are based on a 980 fb-1 data sample collected by the Belle detector at the KEKB asymmetric-energy e+e- collider. Two decays, Λc+→ης0π+ and Λ(1670)π+, are observed for the first time, while the measurements of the other decay modes, Λc+→ηΛπ+ and ης(1385)+, are more precise than those made previously. We obtain relative branching fractions of B(Λc+→ηΛπ+)/B(Λc+→pK-π+)=0.293±0.003±0.014, B(Λc+→ης0π+)/B(Λc+→pK-π+)=0.120±0.006±0.010, B(Λc+→Λ(1670)π+)×B(Λ(1670)→ηΛ)/B(Λc+→pK-π+)=(5.54±0.29±0.73)×10-2, and B(Λc+→ης(1385)+)/B(Λc+→pK-π+)=0.192±0.006±0.016. The mass and width of the Λ(1670) are also precisely determined to be 1674.3±0.8±4.9 MeV/c2 and 36.1±2.4±4.8 MeV, respectively, where the uncertainties are statistical and systematic, respectively.

    We present measurements of the branching fractions for the decays B -> K mu(+)mu(-) and B -> Ke(+)e(-), and their ratio (R-K), using a data sample of 711 fb(-1) that contains 772 x 10(6) B (B) over bar events. The data were collected at the Gamma(4S) resonance with the Belle detector at the KEKB asymmetric-energy e(+)e(-) collider. The ratio RK is measured in five bins of dilepton invariant-mass-squared (q(2)): q(2) is an element of (0.1, 4.0), (4.00, 8.12), (1.0, 6.0), (10.2, 12.8) and (> 14.18) GeV2/c(4), along with the whole q(2) region. The R-K value for q(2) is an element of (1.0, 6.0) GeV2/c(4) is 1.03(-0.24)(+0.28) +/- 0.01. The first and second uncertainties listed are statistical and systematic, respectively. All results for R-K are consistent with Standard Model predictions. We also measure CP-averaged isospin asymmetries in the same q(2) bins. The results are consistent with a null asymmetry, with the largest difference of 2.6 standard deviations occurring for the q(2) is an element of (1.0, 6.0) GeV2/c(4) bin in the mode with muon final states. The measured differential branching fractions, dB/dq(2), are consistent with theoretical predictions for charged B decays, while the corresponding values are below the expectations for neutral B decays. We have also searched for lepton-flavor-violating B -> K mu(+/-)e(-/+) decays and set 90% confidence-level upper limits on the branching fraction in the range of 10(-8) for B+ -> K+ mu(+/-)e(-/+), and B-0 -> K-0 mu(+/-) e(-/+) modes.

    We measure the time-dependent CP violation parameters in B0→KS0KS0KS0 decays using 772×106BB¯ pairs collected at the ϒ(4S) resonance with the Belle detector at the KEKB asymmetric-energy e+e- collider. The obtained mixing-induced and direct CP asymmetries are -0.71±0.23 (stat)±0.05 (syst) and 0.12±0.16 (stat)±0.05 (syst), respectively. These values are consistent with the Standard Model predictions. The significance of CP violation differs from zero by 2.5 standard deviations.

    We report the results of a first search for a doubly charged DDK bound state, denoted the R++, in ϒ(1S) and ϒ(2S) inclusive decays and via direct production in e+e- collisions at s=10.520, 10.580, and 10.867 GeV. The search uses data accumulated with the Belle detector at the KEKB asymmetric-energy e+e- collider. No significant signals are observed in the D+Ds∗+ invariant-mass spectra of all studied modes. The 90% credibility level upper limits on their product branching fractions in ϒ(1S) and ϒ(2S) inclusive decays (B(ϒ(1S, 2S)→R+++anything)×B(R++→D+Ds∗+)), the product values of Born cross section and branching fraction in e+e- collisions (σ(e+e-→R+++anything)×B(R++→D+Ds∗+)) at s=10.520, 10.580, and 10.867 GeV under different assumptions of R++ masses varying from 4.13 to 4.17 GeV/c2 and widths varying from 0 to 5 MeV are obtained.

    Using 980 fb(-1) of data collected with the Belle detector operating at the KEKB asymmetric-energy e(+) e(-) collider, we report a study of the electromagnetic decays of excited charmed baryons Xi(c)(2790) and Xi(c)(2815). A clear signal (8.6 standard deviations) is observed for Xi(c)(2815)(0) -> Xi(0)(c)gamma, and we measure: B[Xi(c)(2815)(0) -> Xi(0)(c)gamma]/B[Xi(c)(2815)(0) -> Xi(c)(2645)(+)pi(-) -> Xi(0)(c)pi(+)pi(-)] = - 0.41 +/- 0.05 +/- 0.03. We also present evidence (3.8 standard deviations) for the similar decay of the Xi(c)(2790)(0) and measure:B[Xi(c)(2790)(0) -> Xi(0)(c)gamma]/B[Xi(c)(2790)(0) -> Xi(c)'(+)pi(-) -> Xi(+)(c)gamma pi(-)] = 0.13 +/- 0.03 +/- 0.02. The first quoted uncertainties are statistical and the second systematic. We find no hint of the analogous decays of the Xi(c)(2815)(+) and Xi(c)(2790)(+) baryons and set upper limits at the 90% confidence level of: B[Xi(c)(2815)(0) -> Xi(0)(c)gamma]/B[Xi(c)(2815)(0) -> Xi(c)(2645)(0)pi(+) -> Xi(+)(c)pi(-)pi(+)] < 0.09, and B[Xi(c)(2790)(+) -> Xi(0)(c)gamma]/B[Xi(c)(2815)(+) -> Xi(c)'(0)pi(+) -> Xi(0)(c)gamma pi(+)] < 0.06. Approximate values of the partial widths of the decays are extracted, which can be used to discriminate between models of the underlying quark structure of these excited states.

    © 2020, The Author(s). The first dedicated search for the ηc2(1D) is carried out using the decays B+→ ηc2(1D)K+, B0 → ηc2(1D)KS0, B0→ ηc2(1D)π−K+, and B+→ ηc2(1D)π+KS0 with ηc2(1D) → hcγ. No significant signal is found. For the ηc2(1D) mass range between 3795 and 3845 MeV/c2, the branching-fraction upper limits are determined to be ℬ(B+→ ηc2(1D)K+) × ℬ(ηc2(1D) → hcγ) < 3.7 × 10−5, ℬ(B0→ ηc2(1D)K0) × ℬ(ηc2(1D) → hcγ) < 3.5 × 10−5, ℬ(B0→ ηc2(1D)π−K+) × ℬ(ηc2(1D) → hcγ) < 1.0 × 10−4, and ℬ(B+→ ηc2(1D)π+KS0) × ℬ(ηc2(1D) → hcγ) < 1.1 × 10−4 at 90% C.L. The analysis is based on the 711 fb−1 data sample collected on the ϒ(4S) resonance by the Belle detector, which operated at the KEKB asymmetric-energy e+e− collider.

    © 2020 authors. The experimental results on the ratios of branching fractions R(D)=B(B→Dτ-ντ)/B(B→Dℓ-νℓ) and R(D∗)=B(B→D∗τ-ντ)/B(B→D∗ℓ-νℓ), where ℓ denotes an electron or a muon, show a long-standing discrepancy with the standard model predictions, and might hint at a violation of lepton flavor universality. We report a new simultaneous measurement of R(D) and R(D∗), based on a data sample containing 772×106 BB events recorded at the ϒ(4S) resonance with the Belle detector at the KEKB e+e- collider. In this analysis the tag-side B meson is reconstructed in a semileptonic decay mode and the signal-side τ is reconstructed in a purely leptonic decay. The measured values are R(D)=0.307±0.037±0.016 and R(D∗)=0.283±0.018±0.014, where the first uncertainties are statistical and the second are systematic. These results are in agreement with the standard model predictions within 0.2, 1.1, and 0.8 standard deviations for R(D), R(D∗), and their combination, respectively. This work constitutes the most precise measurements of R(D) and R(D∗) performed to date as well as the first result for R(D) based on a semileptonic tagging method.

    We report new measurements of the production cross sections of pairs of
    charged pions and kaons as a function of their fractional energies using
    various fractional-energy definitions. Two different fractional-energy
    definitions were used and compared to the conventional fractional-energy
    definition reported previously. The new variables aim at either identifying
    dihadron cross sections in terms of single-hadron fragmentation functions, or
    to provide a means of characterizing the transverse momentum created in the
    fragmentation process. The results were obtained applying the updated
    initial-state radiation correction used in other recent Belle publications on
    light-hadron production cross sections. In addition, production cross sections
    of single charged pions, kaons, and protons were also updated using this
    initial-state radiation correction. The cross sections are obtained from a
    $558\,{\rm fb}^{-1}$ data sample collected at the $\Upsilon(4S)$ resonance with
    the Belle detector at the KEKB asymmetric-energy $e^+ e^-$ collider.

    Theories beyond the standard model often predict the existence of an
    additional neutral boson, the $Z^{\prime}$. Using data collected by the Belle
    II experiment during 2018 at the SuperKEKB collider, we perform the first
    searches for the invisible decay of a $Z^{\prime}$ in the process $e^+ e^- \to
    \mu^+ \mu^- Z^{\prime}$ and of a lepton-flavor-violating $Z^{\prime}$ in $e^+
    e^- \to e^{\pm} \mu^{\mp} Z^{\prime}$. We do not find any excess of events and
    set 90\% credibility level upper limits on the cross sections of these
    processes. We translate the former, in the framework of an $L_{\mu}-L_{\tau}$
    theory, into upper limits on the $Z^{\prime}$ coupling constant at the level of
    $5 \times 10^{-2}$ -- $1$ $M_{Z^\prime}\leq 6$ GeV/$c^2$.

    Using the data sample of 711 fb$^{-1}$ of $\Upsilon(4S)$ on-resonance data
    taken by the Belle detector at the KEKB asymmetric-energy electron-positron
    collider, we present the first measurements of branching fractions of the
    decays $B^{-} \to \bar{\Lambda}_{c}^{-} \Xi_{c}^{'0}$, $B^{-} \to
    \bar{\Lambda}_{c}^{-} \Xi_{c}(2645)^{0}$, and $B^{-} \to \bar{\Lambda}_{c}^{-}
    \Xi_{c}(2790)^{0} $. The signal yields for these decays are extracted from the
    recoil mass spectrum of the system recoiling against $\bar{\Lambda}_{c}^{-}$
    baryons in selected $B^-$ candidates. The branching fraction of $B^{-} \to
    \bar{\Lambda}_{c}^{-} \Xi_{c}(2790)^{0}$ is measured to be $ (1.1 \pm 0.4 \pm
    0.2)\times 10^{-3}$, where the first uncertainty is statistical and the second
    systematic. The 90\% credibility level upper limits on ${\cal B}(B^{-} \to
    \bar{\Lambda}_{c}^{-} \Xi_{c}^{'0})$ and ${\cal B}(B^{-} \to
    \bar{\Lambda}_{c}^{-} \Xi_{c}(2645)^{0})$ are determined to be $6.5\times
    10^{-4}$ and $7.9\times 10^{-4}$, respectively.

    © 2019 authors. Published by the American Physical Society. We present the first measurements of branching fractions of rare tau-lepton decays, τ-→π-ντ+- (=e or μ), using a data sample corresponding to 562 fb-1 collected at a center-of-mass energy of 10.58 GeV with the Belle detector at the KEKB asymmetric-energy e+e- collider. The τ-→π-ντe+e- decay is observed for the first time with 7.0σ significance. The partial branching fraction determined by the structure-dependent mechanisms mediated by either a vector or an axial-vector current for the mass region Mπee>1.05 GeV/c2 is measured to be B(τ-→π-ντe+e-)[Mπ-e+e->1.05 GeV/c2]=(5.90±0.53±0.85±0.11)×10-6, where the first uncertainty is statistical, the second is systematic, and the third is due to model dependence. In the full phase space, due to the different detection efficiencies for the structure-dependent mechanisms mediated by axial-vector and vector currents, the branching fraction varies from BA(τ-→π-ντe+e-)=(1.46±0.13±0.21)×10-5 to BV(τ-→π-ντe+e-)=(3.01±0.27±0.43)×10-5, respectively. An upper limit is set on the branching fraction of the τ-→π-ντμ+μ- decay, B(τ-→π-ντμ+μ-)<1.14×10-5, at the 90% confidence level.

    © 2019, The Author(s). We report a new measurement of the e+e−→ ϒ(nS)π+π− (n = 1, 2, 3) cross sections at energies from 10.52 to 11.02 GeV using data collected with the Belle detector at the KEKB asymmetric-energy e+e− collider. We observe a new structure in the energy dependence of the cross sections; if described by a Breit-Wigner function its mass and width are found to be M=(10752.7±5.9−1.1+0.7)MeV/c2 and Γ=(35.5−11.3−3.3+17.6+3.9)MeV, where the first error is statistical and the second is systematic. The global significance of the new structure including systematic uncertainty is 5.2 standard deviations. We also find evidence for the e+e−→ ϒ (1S)π+π− process at the energy 10.52 GeV, which is below the BB¯ threshold. [Figure not available: see fulltext.]

    © 2019, The Author(s). We present the first model-independent measurement of the CKM unitarity triangle angle ϕ3 using B±→ D(KS0π+π−π0) K± decays, where D indicates either a D0 or D¯ 0 meson. Measurements of the strong-phase difference of the D →KS0π+π−π0 amplitude obtained from CLEO-c data are used as input. This analysis is based on the full Belle data set of 772 × 106BB¯ events collected at the Υ(4S) resonance. We obtain ϕ3 = (5.7−8.8+10.2±3.5±5.7)° and the suppressed amplitude ratio rB = 0.323±0.147±0.023±0.051. Here the first uncertainty is statistical, the second is the experimental systematic, and the third is due to the precision of the strong-phase parameters measured from CLEO-c data. The 95% confidence interval on ϕ3 is (−29.7, 109.5)°, which is consistent with the current world average. [Figure not available: see fulltext.]

    © 2019 authors. Published by the American Physical Society. We present a new measurement of the Cabibbo-Kobayashi-Maskawa matrix element |Vcb| from B0→D∗-ℓ+νℓ decays, reconstructed with the full Belle data set of 711 fb-1 integrated luminosity. Two form factor parametrizations, originally conceived by the Caprini-Lellouch-Neubert (CLN) and the Boyd, Grinstein and Lebed (BGL) groups, are used to extract the product F(1)ηEW|Vcb| and the decay form factors, where F(1) is the normalization factor and ηEW is a small electroweak correction. In the CLN parametrization we find F(1)ηEW|Vcb|=(35.06±0.15±0.56)×10-3, ρ2=1.106±0.031±0.007, R1(1)=1.229±0.028±0.009, R2(1)=0.852±0.021±0.006. For the BGL parametrization we obtain F(1)ηEW|Vcb|=(34.93±0.23±0.59)×10-3, which is consistent with the world average when correcting for F(1)ηEW. The branching fraction of B0→D∗-ℓ+νℓ is measured to be B(B0→D∗-ℓ+νℓ)=(4.90±0.02±0.16)%. We also present a new test of lepton flavor universality violation in semileptonic B decays, B(B0→D∗-e+ν)B(B0→D∗-μ+ν)=1.01±0.01±0.03. The errors quoted correspond to the statistical and systematic uncertainties, respectively.

Using data samples of e+e- collisions collected at the I(1S), I(2S), and I(3S) resonances with the Belle detector, we search for the three-body decay of the ω(2012) baryon to KπΞ. This decay is predicted to dominate for models describing the ω(2012) as a KΞ(1530) molecule. No significant ω(2012) signals are observed in the studied channels, and 90% credibility level upper limits on the ratios of the branching fractions relative to KΞ decay modes are obtained.

Further distribution of this work must maintain attribution to the author(s) and the published article's title, journal citation, and DOI. Funded by SCOAP 3 . We present the first measurements of the absolute branching fractions of Ξc+ decays into Ξ-π+π+ and pK-π+ final states. Our analysis is based on a data set of (772±11)×106 BB̄ pairs collected at the (4S) resonance with the Belle detector at the KEKB e+e- collider. We measure the absolute branching fraction of B̄0→Λ̄c-Ξc+ with the Ξc+ recoiling against Λ̄c- in B̄0 decays resulting in B(B̄0→Λ̄c-Ξc+)=[1.16±0.42(stat.)±0.15(syst.)]×10-3. We then measure the product branching fractions B(B̄0→Λ̄c-Ξc+)B(Ξc+→Ξ-π+π+) and B(B̄0→Λ̄c-Ξc+)B(Ξc+→pK-π+). Dividing these product branching fractions by B̄0→Λ̄c-Ξc+ yields B(Ξc+→Ξ-π+π+)=[2.86±1.21(stat.)±0.38(syst.)]% and B(Ξc+→pK-π+)=[0.45±0.21(stat.)±0.07(syst.)]%. Our result for B(Ξc+→Ξ-π+π+) can be combined with Ξc+ branching fractions measured relative to Ξc+→Ξ-π+π+ to set the absolute scale for many Ξc+ branching fractions.

We report measurements of the production cross sections of charged pions, kaons, and protons as a function of fractional energy, the event-shape variable called thrust, and the transverse momentum with respect to the thrust axis. These measurements access the transverse momenta created in the fragmentation process, which are of critical importance to the understanding of any transverse-momentum-dependent distribution and fragmentation functions. The low transverse-momentum part of the cross sections can be well described by Gaussians in transverse momentum as is generally assumed but the fractional-energy dependence is nontrivial and different hadron types have varying Gaussian widths. The width of these Gaussians decreases with thrust and shows an initially rising, then decreasing fractional-energy dependence. The widths for pions and kaons are comparable within uncertainties, while those for protons are significantly narrower. These single-hadron cross sections and Gaussian widths are obtained from a 558 fb-1 data sample collected at the (4S) resonance with the Belle detector at the KEKB asymmetric-energy e+e- collider.

    © 2019 The Author(s). This paper introduces a new approach to measure the muon magnetic moment anomaly aμ = (g - 2)/2 and the muon electric dipole moment (EDM) dμ at the J-PARC muon facility. The goal of our experiment is to measure aμ and dμ using an independent method with a factor of 10 lower muon momentum, and a factor of 20 smaller diameter storage-ring solenoid compared with previous and ongoing muon g - 2 experiments with unprecedented quality of the storage magnetic field. Additional significant differences from the present experimental method include a factor of 1000 smaller transverse emittance of the muon beam (reaccelerated thermal muon beam), its efficient vertical injection into the solenoid, and tracking each decay positron from muon decay to obtain its momentum vector. The precision goal for aμ is a statistical uncertainty of 450 parts per billion (ppb), similar to the present experimental uncertainty, and a systematic uncertainty less than 70 ppb. The goal for EDM is a sensitivity of 1.5 × 10-21 ecm.

    © 2019 authors. We report the results of a search for the B→Y(4260)K, Y(4260)→J/ψπ+π- decays. This study is based on a data sample corresponding to an integrated luminosity of 711 fb-1, collected at the (4S) resonance with the Belle detector at the KEKB asymmetric-energy e+e- collider. We investigate the J/ψπ+π- invariant mass distribution in the range 4.0 to 4.6 GeV/c2 using both B+→J/ψπ+π-K+ and B0→J/ψπ+π-KS0 decays. We find excesses of events above the background levels, with significances of 2.1 and 0.9 standard deviations for charged and neutral B→Y(4260)K decays, respectively, taking into account the systematic uncertainties. These correspond to upper limits on the product of branching fractions, B(B+→Y(4260)K+)×B(Y(4260)→J/ψπ+π-)<1.4×10-5 and B(B0→Y(4260)K0)×B(Y(4260)→J/ψπ+π-)<1.7×10-5 at the 90% confidence level.

    © 2019 Authors. Published by the American Physical Society. We present the first measurements of absolute branching fractions of Ξc 0 decays into Ξ-π+, ΛK-π+, and pK-K-π+ final states. The measurements are made using a dataset comprising (772±11)×106 BB̄ pairs collected at the (4S) resonance with the Belle detector at the KEKB e+e-collider. We first measure the absolute branching fraction for B-→Λ̄c-Ξc 0 using a missing-mass technique; the result is B(B-→Λ̄c-Ξc 0 )=(9.51±2.10±0.88)×10-4. We subsequently measure the product branching fractions B(B-→Λ̄c-Ξc 0 )B(Ξc 0 →Ξ-π+), B(B-→Λ̄c-Ξc 0 )B(Ξc 0 →ΛK-π+), and B(B-→Λ̄c-Ξc 0 )B(Ξc 0 →pK-K-π+) with improved precision. Dividing these product branching fractions by the result for B-→Λ̄c-Ξc 0 yields the following branching fractions: B(Ξc 0 →Ξ-π+)=(1.80±0.50±0.14)%, B(Ξc 0 →ΛK-π+)=(1.17±0.37±0.09)%, and B(Ξc 0 →pK-K-π+)=(0.58±0.23±0.05)%. For the above branching fractions, the first uncertainties are statistical and the second are systematic. Our result for B(Ξc 0 →Ξ-π+) can be combined with Ξc 0 branching fractions measured relative to Ξc 0 →Ξ-π+ to yield other absolute Ξc 0 branching fractions.

    © 2019 authors. Published by the American Physical Society. We report the first observation of the double strange baryon Ξ(1620)0 in its decay to Ξ-π+ via Ξc+→Ξ-π+π+ decays based on a 980 fb-1 data sample collected with the Belle detector at the KEKB asymmetric-energy e+e- collider. The mass and width are measured to be 1610.4±6.0(stat)-4.2+6.1 (syst) MeV/c2 and 59.9±4.8(stat)-7.1+2.8(syst) MeV, respectively. We obtain 4.0σ evidence of the Ξ(1690)0 with the same data sample. These results shed light on the structure of hyperon resonances with strangeness S=-2.

We report the study of B+→pΛ̄K+K- and B+→p̄ΛK+K+ decays using a 772×106 BB̄ pair data sample recorded on the Ï (4S) resonance with the Belle detector at KEKB. The following branching fractions are measured: B(B+→pΛ̄K+K-)=(4.10-0.43+0.45±0.50)×10-6, B(B+→p̄ΛK+K+)=(3.70-0.37+0.39±0.44)×10-6, B(ηc→pΛ̄K-+c.c.)=(2.83-0.34+0.36±0.35)×10-3 and B(B+→pΛ̄φ)=(7.95±2.09±0.77)×10-7, where c.c. denotes the corresponding charge-conjugation process. The intermediate resonance decays are excluded in the four-body decay measurements. We also find evidence for B(ηc→Λ(1520)Λ̄+c.c.)=(3.48±1.48±0.46)×10-3 and B(B+→Λ(1520)Λ̄K+)=(2.23±0.63±0.25)×10-6. No significant signals are found for J/ψ→Λ(1520)Λ̄+c.c. and B+→Λ̄(1520)ΛK+; we set the 90% confidence level upper limits on their decay branching fractions as <1.80×10-3 and <2.08×10-6, respectively.

Further distribution of this work must maintain attribution to the author(s) and the published article's title, journal citation, and DOI. Funded by SCOAP 3 . We report measurements of isospin asymmetry Δ0- and difference of direct CP asymmetries ΔACP between charged and neutral B→Xsγ decays. This analysis is based on the data sample containing 772×106BB̄ pairs that was collected with the Belle detector at the KEKB energy-asymmetric e+e- collider. Using a sum-of-exclusive technique with invariant Xs mass up to 2.8 GeV/c2, we obtain Δ0-=[-0.48±1.49(stat)±0.97(syst)±1.15(f+-/f00)]% and ΔACP=[+3.69±2.65(stat)±0.76(syst)]%, where the last uncertainty for Δ0- is due to the uncertainty on the production ratio of B+B- to B0B̄0 in Ï (4S) decays. The measured value of Δ0- is consistent with zero, allowing us to constrain the resolved photon contribution in the B→Xsγ, and improve the branching fraction prediction. The result for ΔACP is consistent with the prediction of the SM. We also measure the direct CP asymmetries for charged and neutral B→Xsγ decays. All the measurements are the most precise to date.

    © 2019 authors. Published by the American Physical Society. We report on the first Belle search for a light CP-odd Higgs boson, A0, that decays into low mass dark matter, χ, in final states with a single photon and missing energy. We search for events produced via the dipion transition (2S)→ (1S)π+π-, followed by the on-shell process (1S)→γA0 with A0→χχ, or by the off-shell process (1S)→γχχ. Utilizing a data sample of 157.3×106 (2S) decays, we find no evidence for a signal. We set limits on the branching fractions of such processes in the mass ranges MA0<8.97 GeV/c2 and Mχ<4.44 GeV/c2. We then use the limits on the off-shell process to set competitive limits on WIMP-nucleon scattering in the WIMP mass range below 5 GeV/c2.

We measure a set of five kinematically dependent CP asymmetries, of which four asymmetries are measured for the first time. The set of asymmetry measurements can be sensitive to CP violation via interference between the different partial-wave contributions to the decay and performed on other pseudoscalar decays. We find no evidence of CP violation.

    © 2019 authors. We report the first observation of the spontaneous polarization of Λ and Λ hyperons transverse to the production plane in e+e- annihilation, which is attributed to the effect arising from a polarizing fragmentation function. For inclusive Λ/Λ production, we also report results with subtracted feed-down contributions from Σ0 and charm. This measurement uses a dataset of 800.4 fb-1 collected by the Belle experiment at or near a center-of-mass energy of 10.58 GeV. We observe a significant polarization that rises with the fractional energy carried by the Λ/Λ hyperon.

    © 2018 authors. Published by the American Physical Society. We present first evidence that the cosine of the CP-violating weak phase 2β is positive, and hence exclude trigonometric multifold solutions of the Cabibbo-Kobayashi-Maskawa (CKM) Unitarity Triangle using a time-dependent Dalitz plot analysis of B0→D(∗)h0 with D→KS0π+π- decays, where h0 {π0,η,ω} denotes a light unflavored and neutral hadron. The measurement is performed combining the final data sets of the BABAR and Belle experiments collected at the (4S) resonance at the asymmetric-energy B factories PEP-II at SLAC and KEKB at KEK, respectively. The data samples contain (471±3)×106BB pairs recorded by the BABAR detector and (772±11)×106BB pairs recorded by the Belle detector. The results of the measurement are sin2β=0.80±0.14(stat)±0.06(syst)±0.03(model) and cos2β=0.91±0.22(stat)±0.09(syst)±0.07(model). The result for the direct measurement of the angle β of the CKM Unitarity Triangle is β=[22.5±4.4(stat)±1.2(syst)±0.6(model)]°. The measurement assumes no direct CP violation in B0→D(∗)h0 decays. The quoted model uncertainties are due to the composition of the D0→KS0π+π- decay amplitude model, which is newly established by performing a Dalitz plot amplitude analysis using a high-statistics e+e-→cc data sample. CP violation is observed in B0→D(∗)h0 decays at the level of 5.1 standard deviations. The significance for cos2β>0 is 3.7 standard deviations. The trigonometric multifold solution π/2-β=(68.1±0.7)° is excluded at the level of 7.3 standard deviations. The measurement resolves an ambiguity in the determination of the apex of the CKM Unitarity Triangle.

    © 2018 authors. Published by the American Physical Society. We report the observation of I(2S)→γηb(1S) decay based on an analysis of the inclusive photon spectrum of 24.7 fb-1 of e+e- collisions at the I(2S) center-of-mass energy collected with the Belle detector at the KEKB asymmetric-energy e+e- collider. We measure a branching fraction of B[I(2S)→γηb(1S)]=(6.1-0.7-0.6+0.6+0.9)×10-4 and derive an ηb(1S) mass of 9394.8-3.1-2.7+2.7+4.5 MeV/c2, where the uncertainties are statistical and systematic, respectively. The significance of our measurement is greater than 7 standard deviations, constituting the first observation of this decay mode.

    © 2018 authors. Published by the American Physical Society. We present the result of the search for the rare B meson decay of B+→+νγ with =e,μ. For the search the full data set recorded by the Belle experiment of 711 fb-1 integrated luminosity near the (4S) resonance is used. Signal candidates are reconstructed for photon energies Eγ larger than 1 GeV using a novel multivariate tagging algorithm. The novel algorithm fully reconstructs the second B meson produced in the collision using hadronic modes and was specifically trained to recognize the signal signature in combination with hadronic tag-side B meson decays. This approach greatly enhances the performance. Background processes that can mimic this signature, mainly charmless semileptonic decays and continuum processes, are suppressed using multivariate methods. The number of signal candidates is determined by analyzing the missing mass squared distribution as inferred from the signal side particles and the kinematic properties of the tag-side B meson. No significant excess over the background-only hypothesis is observed and upper limits on the partial branching fraction ΔB with Eγ>1 GeV individually for electron and muon final states as well as for the average branching fraction of both lepton final states are reported. We find a Bayesian upper limit of ΔB(B+→+νγ)<3.0×10-6 at 90% CL and also report an upper limit on the first inverse moment of the light-cone distribution amplitude of the B meson of λB>0.24 GeV at 90% CL.

    © 2018 authors. Published by the American Physical Society. We measure the branching fraction and time-dependent CP-violating asymmetry for B0→J/ψπ0 decays using a data sample of 711 fb-1 collected on the (4S) resonance by the Belle experiment running at the KEKB e+e- collider. The branching fraction is measured to be B(B0→J/ψπ0)=[1.62±0.11(stat)±0.06(syst)]×10-5, which is the most precise measurement to date. The measured CP asymmetry parameters are S=-0.59±0.19(stat)±0.03(syst) and A=-0.15±0.14(stat)+0.04-0.03(syst). The mixing-induced CP asymmetry (S) differs from the case of no CP violation by 3.0 standard deviations, and the direct CP asymmetry (A) is consistent with zero.

A significant γχc1 signal is observed for the first time at s=10.58 GeV with a significance of 5.1σ including systematic uncertainties. No significant excesses for γχc0, γχc2, and γηc final states are found, and we set 90% credibility level upper limits on the Born cross sections (σB) at 10.52 GeV, 10.58 GeV, and 10.867 GeV. Together with cross sections measured by BESIII at lower center-of-mass energies, the energy dependency of σB(e+e-→γχc1) is obtained.

We report searches for the processes e+e-→π+π-π0χbJ and e+e-→φχbJ (J=1, 2) based on data samples collected by the Belle experiment at the KEKB collider. We report the first observation of the process e+e-→(π+π-π0)non-ωχb1 and first evidence for e+e-→ωχbJ in the vicinity of the ?(11020) resonance, with center-of-mass energies from 10.96 to 11.05 GeV. The significances for (π+π-π0)non-ωχb1 and ωχbJ are greater than 5.3σ and 4.0σ, respectively. We also investigate the energy dependence of the e+e-→π+π-π0χbJ cross section, but we cannot determine whether the contributions are from the ?(10860) and ?(11020) resonances or nonresonant continuum processes. The signals for e+e-→φχbJ are not significant, and the upper limits of the Born cross sections at the 90% confidence level are 0.7 and 1.0 pb for e+e-→φχb1 and φχb2, respectively, for center-of-mass energies from 10.96 to 11.05 GeV.

    © 2018 authors. Published by the American Physical Society. We have searched for the lepton-flavor-violating decay B0→K∗0μ±e using a data sample of 711 fb-1 that contains 772×106 BB̄ pairs. The data were collected near the (4S) resonance with the Belle detector at the KEKB asymmetric-energy e+e- collider. No signals were observed, and we set 90% confidence level upper limits on the branching fractions of B(B0→K∗0μ+e-)<1.2×10-7, B(B0→K∗0μ-e+)<1.6×10-7, and, for both decays combined, B(B0→K∗0μ±e)<1.8×10-7. These are the most stringent limits on these decays to date.

    © 2018, The Author(s). We study bottomonium production in association with an η meson in e+e- annihilations near the Υ(5 S) , at a centre-of-mass energy of s=10.866 GeV. The results are based on the 121.4 fb- 1 data sample collected by the Belle experiment at the asymmetric-energy KEKB collider. Only the η meson is reconstructed and the missing-mass spectrum of η candidates is investigated. We observe the e+e-→ ηΥJ(1 D) process and find evidence for the e+e-→ ηΥ(2 S) process, while no significant signals of Υ(1 S) , hb(1 P) , nor hb(2 P) are found. Cross sections for the studied processes are reported.

    © 2018 authors. Published by the American Physical Society. We report the results of a search for the rare, purely leptonic decay B-→μ-ν μ performed with a 711 fb-1 data sample that contains 772×106 BB pairs, collected near the (4S) resonance with the Belle detector at the KEKB asymmetric-energy e+e- collider. The signal events are selected based on the presence of a high momentum muon and the topology of the rest of the event showing properties of a generic B-meson decay, as well as the missing energy and momentum being consistent with the hypothesis of a neutrino from the signal decay. We find a 2.4 standard deviation excess above background including systematic uncertainties, which corresponds to a branching fraction of B(B-→μ-νμ)=(6.46±2.22±1.60)×10-7 or a frequentist 90% confidence level interval on the B-→μ-ν μ branching fraction of [2.9,10.7]×10-7.

    © 2018 authors. Published by the American Physical Society. We report a measurement of the branching fractions of the decays B→D(∗)πν. The analysis uses 772×106 BB. pairs produced in e+e-→(4S) data recorded by the Belle experiment at the KEKB asymmetric-energy e+e- collider. The tagging B meson in the decay is fully reconstructed in a hadronic decay mode. On the signal side, we reconstruct the decay B→D(∗)πν(=e,μ). The measured branching fractions are B(B+→D-π++ν)=[4.55±0.27 (stat.)±0.39 (syst.)]×10-3, B(B0→D.0π-+ν)=[4.05±0.36 (stat.)±0.41 (syst.)]×10-3, B(B+→D∗-π++ν)=[6.03±0.43 (stat.)±0.38 (syst.)]×10-3, and B(B0→D.∗0π-+ν)=[6.46±0.53 (stat.)±0.52 (syst.)]×10-3. These are in good agreement with the current world-average values.

We measure the inclusive production cross sections of hyperons and charmed baryons from e+e- annihilation using a 800 fb-1 data sample taken near the (4S) resonance with the Belle detector at the KEKB asymmetric-energy e+e- collider. The feed-down contributions from heavy particles are subtracted using our data, and the direct production cross sections are presented for the first time. The production cross sections divided by the number of spin states for S=-1 hyperons follow an exponential function with a single slope parameter except for the Σ(1385)+ resonance. Suppression for Σ(1385)+ and Ξ(1530)0 hyperons is observed. Among the production cross sections of charmed baryons, a factor of 3 difference for Λc+ states over Σc states is observed. This observation suggests a diquark structure for these baryons.

    © 2018, The Author(s). We report the first observation of the Ξ c(2930) 0 charmed-strange baryon with a significance greater than 5σ. The Ξ c(2930) 0 is found in its decay to K-Λc+ in B-→K-Λc+Λ¯c- decays. The measured mass and width are [2928.9±3.0(stat.)-12.0+0.9(syst.)] MeV/c2 and [19.5±8.4(stat.)-7.9+5.9(syst.)] MeV, respectively, and the product branching fraction is B(B-→Ξc(2930)0Λ¯c-)B(Ξc(2930)0→K-Λc+)=[1.73±0.45(stat.)±0.21(syst.)]×10-4. We also measure B(B-→K-Λc+Λ¯c-)=[4.80±0.43(stat.)±0.60(syst.)]×10-4 with improved precision, and search for the charmonium-like state Y(4660) and its spin partner, Yη, in the Λc+Λ¯c- invariant mass spectrum. No clear signals of the Y(4660) nor its spin partner are observed and the 90% credibility level (C.L.) upper limits on their production rates are determined. These measurements are obtained from a sample of (772 ± 11) × 10 6BB¯ pairs collected at the Υ (4 S) resonance by the Belle detector at the KEKB asymmetric energy electron–positron collider.

    © 2018 authors. We report a measurement of the cross section for KS0 pair production in single-tag two-photon collisions, γ∗γ→KS0KS0, for Q2 up to 30 GeV2, where Q2 is the negative of the invariant mass squared of the tagged photon. The measurement covers the kinematic range 1.0 GeV<W<2.6 GeV and |cosθ∗|<1.0 for the total energy and kaon scattering angle, respectively, in the γ∗γ center-of-mass system. These results are based on a data sample of 759 fb-1 collected with the Belle detector at the KEKB asymmetric-energy e+e- collider. For the first time, the transition form factor of the f2′(1525) meson is measured separately for the helicity-0, -1, and -2 components and also compared with theoretical calculations. We have derived the cross section for the process for W<2.6 GeV from 121 signal candidate events. Finally, the γ∗γ partial decay widths of the χc0 and χc2 mesons are measured as a function of Q2 based on 10 candidate events in total.

The Michel parameters are measured in an unbinned maximum likelihood fit to the kinematic distribution of e + e - → τ + τ - → (π + π 0 ν τ )(l - ν τ ν l γ)(l = e or μ The measured values of the Michel parameters are η = -1.3 ± 1.5 ± 0.8 and ξκ = 0.5 ± 0.4 ± 0.2, where the first error is statistical and the second is systematic. This is the first measurement of these parameters. These results are consistent with the Standard Model predictions within their uncertainties, and constrain the coupling constants of the generalized weak interaction.

We report the most precise measurements to date of the relative branching fractions of the Ωc0 into Ω-π+π0, Ω-π+π-π+, Ξ-K-π+π+, and Ξ0K-π+, as well as the first measurements of the branching fractions of the Ωc0 into Ξ-K̄0π+, Ξ0K̄0, and ΛK̄0K̄0, all with respect to the Ω-π+ decay. In addition, we investigate the resonant substructure of these modes. Finally, we present a limit on the branching fraction for the decay Ωc0→Σ+K-K-π+.

The τ polarization Pτ(D∗) in two-body hadronic τ decays is measured, as well as the ratio of the branching fractions R(D∗)=B(B̄→D∗τ-ν̄τ)/B(B̄→D∗-ν̄), where - denotes an electron or a muon. Our results, Pτ(D∗)=-0.38±0.51(stat)-0.16+0.21(syst) and R(D∗)=0.270±0.035(stat)-0.025+0.028(syst), are consistent with the theoretical predictions of the standard model. The polarization values of Pτ(D∗)>+0.5 are excluded at the 90% confidence level.

The analysis is based on a data sample collected with the Belle detector with an integrated luminosity of 951 fb-1. The accuracy of the cross section measurement is increased by a factor of 2 over the first Belle study.

    © 2017, The Author(s). This article reports world averages of measurements of b-hadron, c-hadron, and τ-lepton properties obtained by the Heavy Flavor Averaging Group using results available through summer 2016. For the averaging, common input parameters used in the various analyses are adjusted (rescaled) to common values, and known correlations are taken into account. The averages include branching fractions, lifetimes, neutral meson mixing parameters, CP violation parameters, parameters of semileptonic decays, and Cabbibo–Kobayashi–Maskawa matrix elements.

    We search for the J(PC) = 0(--) and 1(+-) light tetraquark states with masses up to 2.46 GeV/c(2) in gamma(1S) and gamma(2S) decays with data samples of (102 +/- 2) million and (158 +/- 4) million events, respectively, collected with the Belle detector. No significant signals are observed in any of the studied production modes, and 90% credibility level (C. L.) upper limits on their branching fractions in Upsilon(1S) and Upsilon(2S) decays are obtained. The inclusive branching fractions of the Upsilon(1S) and Upsilon(2S) decays into final states with f(1)(1285) are measured to be B(Upsilon(1S) -&gt; f(1)(1285) + anything) = (46 +/- 28(stat) +/- 13(syst)) x 10(-4) and B(Upsilon(2S) -&gt; f(1)(1285) + anything) = (22 +/- 15(stat) +/- 6.3(syst)) x 10(-4). The measured chi(b2) -&gt; J/Psi + anything branching fraction is measured to be (1.50 +/- 0.34(stat) +/- 0.22(syst)) x 10(-3), and 90% C. L. upper limits for the chi(b0;b1) -&gt; J/Psi + anything branching fractions are found to be 2.3 x 10(-3) and 1.1 x 10(-3), respectively. For B(chi(b1) -&gt; omega + anything), the branching fraction is measured to be (4.9 +/- 1.3(stat) +/- 0.6(syst) x 10(-2). All results reported here are the first measurements for these modes.

    We report the first evidence for isospin violation in B -&gt; K*gamma and the first measurement of the difference of CP asymmetries between B+-&gt;.K*(+)gamma and B-0 -&gt; K-*0 gamma. This analysis is based on the data sample containing 772 x 10(6)BB pairs that was collected with the Belle detector at the KEKB energy-asymmetric e(+)e(-) collider. We find evidence for the isospin violation with a significance of 3.1 sigma, Delta(0+) = [+6.2 +/- 1.5(stat) +/- 0.6(syst) +/- 1.2(f (+-)/f(00))] %, where the third uncertainty is due to the uncertainty on the fraction of B+B- to (BB0)-B-0 production in gamma(4S) decays. The measured value is consistent with predictions of the standard model. The result for the difference of CP asymmetries is Delta A(CP) = [+2.4 +/- 2.8(stat) +/- 0.5(syst)] %, consistent with zero. The measured branching fractions and CP asymmetries for charged and neutral B meson decays are the most precise to date. We also calculate the ratio of branching fractions of B-0 -&gt; K-*0 gamma to B-s(0) -&gt; phi gamma.

    We present the results of a search for the rare decays B -&gt; h nu(nu) over bar, where h stands for K+, K-S(0), K*(+); K*(0); pi(+); pi(0), rho(+) and rho(0). The results are obtained with 772 x 10(6) B (B) over bar pairs collected with the Belle detector at the KEKB e(+)e(-) collider. We reconstruct one B meson in a semileptonic decay and require a single h meson but nothing else on the signal side. We observe no significant signal and set upper limits on the branching fractions. The limits set on the B-0 -&gt; K-S(0)nu(nu) over bar, B-0 -&gt; K*(0)nu(nu) over bar, B+ -&gt; pi(+)nu(nu) over bar, B-0 -&gt; pi(0)nu(nu) over bar, B+ -&gt; rho(+)nu(nu) over bar, and B-0 -&gt; rho(0)nu(nu) over bar channels are the world's most stringent.

    We report a study of the decay D-0 -&gt; (KSKS0)-K-0 using 921 fb(-1) of data collected at or near the (sic)(4S) and (sic)(5S) resonances with the Belle detector at the KEKB asymmetric energy e(+)e(-) collider. The measured time-integrated CP asymmetry is A(CP)(D-0 -&gt; (KSKS0)-K-0) = (-0.02 +/- 1.53 +/- 0.02 +/- 0.17)%, and the branching fraction is B(D-0 -&gt; (KSKS0)-K-0) = (1.321 +/- 0.023 +/- 0.036 +/- 0.044) x 10(-4), where the first uncertainty is statistical, the second is systematic, and the third is due to the normalization mode (D-0 -&gt; K-S(0)pi(0)). These results are significantly more precise than previous measurements available for this mode. The A(CP) measurement is consistent with the standard model expectation.

    $X(3915)$, and set the 90$\%$ confidence level upper limits: ${\cal B}(B^{+}
    \to X(3872) K^{+} )<2.7 \times 10^{-4}$ and ${\cal B}(B^{+} \to X(3915) K^{+}
    )<2.9 \times 10^{-4}$. These represent the most stringent upper limit for
    ${\cal B}(B^{+} \to X(3872) K^{+} )$ to date and the first measurement for
    ${\cal B}(B^{+} \to X(3915) K^{+} )$. The measured branching fractions for
    $\eta_{c}$ and $\eta_{c}(2S)$ are the most precise to date: ${\cal B}(B^{+} \to
    \eta_{c} K^{+} )=(12.3\pm0.8\pm0.7) \times 10^{-4}$ and ${\cal B}(B^{+} \to
    \eta_{c}(2S)K^{+}) =(4.9\pm1.1\pm0.3) \times 10^{-4}$ , where the first and
    second uncertainties are statistical and systematic, respectively.

    We have searched for the Cabibbo-suppressed decay Lambda(+)(c) -&gt; pi p(0) in e(+) e(-) collisions using a data sample corresponding to an integrated luminosity of 915 fb(-1). The data were collected by the Belle experiment at the KEKB e(+) e(-) asymmetric-energy collider running at or near the (4S) and (5S) resonances. No significant signal is observed, and we set an upper limit on the branching fraction of B(Lambda(+)(c) -&gt; phi p(0)) &lt; 15.3 x 10(-5) at 90% confidence level. The contribution of nonresonant Lambda(+)(c) -&gt; K+ K- p pi(0) decays is found to be consistent with zero, and the corresponding upper limit on its branching fraction is set to be B(Lambda(+)(c) -&gt;. K+ K- p pi(0))(NR) &lt; 6.3 x 10(-5) at 90% confidence level. We also search for an intermediate hidden-strangeness pentaquark decay P-s(+) -&gt; phi p. We see no evidence for this intermediate decay and set an upper limit on the product branching fraction of B(Lambda(+)(c) -&gt; P-s(+) pi(0)) x B(P-s(+) -&gt; phi p) &lt; 8.3 x 10(-5) at 90% confidence level. Finally, we measure the branching fraction for the Cabibbo-favored decay Lambda(+)(c) -&gt; K- pi(+) p pi(0); the result is B(Lambda(+)(c) -&gt; K- pi(+) p pi(0)) = (4.42 +/- 0.05(stat)+/- 0.12(syst)+/- 0.16(norm))%, which is the most precise measurement to date.

    We study hadronic transitions between bottomonium states using 496 fb(-1) data collected at the gamma(4S) resonance with the Belle detector at the KEKB asymmetric energy e(+)e(-) collider. We measure: B(gamma(4S) -&gt; pi(+)pi(-)gamma(1S)) = (8.2 +/- 0.5(stat.)+/- 0.4(syst.)) x 10(-5), B(gamma(4S) -&gt; pi(+)pi(-)gamma(2S)) = (7.9 +/- 1.0(stat.)+/- 0.4(syst.)) x 10(-5), and B(gamma(4S) -&gt; eta gamma(1S)) = (1.70 +/- 0.23(stat.) +/- 0.08(syst.)) x 10(-4). We measure the ratio of branching fractions R=B(gamma(4S) -&gt; eta gamma(1S))/B(gamma(4S) -&gt; pi(+)pi(-)gamma(1S)) = 2.07 +/- 0.30(stat.)+/- 0.11(syst.). We search for the decay gamma(1(3)D(1,2)) -&gt; eta gamma(1S), but do not find significant evidence for such a transition. We also measure the initial state radiation production cross sections of the gamma(2S,3S) resonances and we find values compatible with the expected ones. Finally, the analysis of the gamma(4S) -&gt; pi(+)pi(-)gamma(1S) events shows indications for a resonant contribution due to the f(0)(980) meson.

    We report a study of the charmless hadronic decay of the charged B meson to the three-body final state K+K-pi(+). The results are based on a data sample that contains 772 x 10(6) B (B) over bar pairs collected at the Y (4S) resonance with the Belle detector at the KEKB asymmetric-energy e(+)e(-) collider. The measured inclusive branching fraction and direct CP asymmetry are (5.38 +/- 0.40 +/- 0.35) x 10(-6) and -0.170 +/- 0.073 +/- 0.017, respectively, where the first uncertainties are statistical and the second are systematic. The K+K- invariant mass distribution of the signal candidates shows an excess in the region below 1.5 GeV/c(2), which is consistent with the previous studies from BABAR and LHCb. In addition, strong evidence of a large direct CP asymmetry is found in the low K+K- invariant-mass region.

    The inclusive cross sections for dihadrons of charged pions and kaons (e(+)e(-) -&gt; hhX) in electron-positron annihilation are reported. They are obtained as a function of the total fractional energy and invariant mass for any di-hadron combination in the same hemisphere as defined by the thrust event-shape variable and its axis. Since same-hemisphere dihadrons can be assumed to originate predominantly from the same initial parton, di-hadron fragmentation functions are probed. These di-hadron fragmentation functions are needed as an unpolarized baseline in order to quantitatively understand related spindependent measurements in other processes and to apply them to the extraction of quark transversity distribution functions in the nucleon. The di- hadron cross sections are obtained from a 655 fb(-1) data sample collected at or near the Y (4S) resonance with the Belle detector at the KEKB asymmetric-energy e(+)e(-) collider.

    We measure the branching fraction and CP violation asymmetry in the decay B-0 -&gt; pi(0)pi(0), using a data sample of 752 x 10(6) B (B) over bar pairs collected at the Y(4S) resonance with the Belle detector at the KEKB e(+)e(-) collider. The obtained branching fraction and direct CP asymmetry are B(B -&gt; pi(0)pi(0)) = [1.31 +/- 0.19(stat) +/- 0.19(syst)] x 10(-6) and A(CP) = +0.14 +/- 0.36(stat) +/- 0.10(syst), respectively. The signal significance, including the systematic uncertainty, is 6.4 standard deviations. We combine these results with Belle's earlier measurements of B-0 -&gt; pi(+)pi(-) and B-+/- -&gt; pi(+/-)pi(0) to exclude the CP-violating parameter phi(2) from the range 15.5 degrees &lt; phi(2) &lt; 75.0 degrees at 95% confidence level.

    We search for the charged lepton flavor violating (cLFV) two-body decay, τ→lX using data samples collected with the Belle detector at the KEKB asymmetric-energy e+e− collider, where l is muon or electron and X is a missing particle. One of candidates for an X particle is, for example, a light Z′ boson in the Lμ−Lτ model. This decay mode has been searched for in the ARGUS experiment in 1995. No evidence of the signal has been found and they set upper limits for B(τ→lX)/B(τ→lνν) at several values of X mass. With the Belle data sample, we can perform a much more sensitive search. In this paper we report the estimation of the sensitivities and upper limits of the branching fraction for τ→μX depending on the X mass with a 1 ab−1 data sample.

    We perform a full amplitude analysis of the process e(+)e(-)-&gt; J/psi D (D) over bar, where D refers to either D-0 or D+. A new charmoniumlike state X*(3860) that decays to D (D) over bar is observed with a significance of 6.5 sigma. Its mass is (3862(-32)(+26) (+40)(-13) )MeV= c(2), and its width is (201(-67) (+154)(-82) (+88)) MeV. The J(PC) = 0(++) hypothesis is favored over the 2(++) hypothesis at the level of 2.5s. The analysis is based on the 980 fb(-1) data sample collected by the Belle detector at the asymmetric-energy e(+)e(-)collider KEKB.

    We report the first measurement of the tau lepton polarization P-tau(D*) in the decay (B) over bar -&gt; D* tau(-) (v) over bar (tau) as well as a newmeasurement of the ratio of the branching fractions R(D*) = B((B) over bar -&gt; D* tau(-) (v) over bar (tau)) / B((B) over bar -&gt; D* l(-) (v) over bar (l)), where l(-) denotes an electron or a muon, and the tau is reconstructed in the modes tau(-) -&gt; pi(-) v(tau) and tau(-) -&gt; rho(-) v(tau). We use the full data sample of 772 x 10(6) B (B) over bar pairs recorded with the Belle detector at the (KEKB) over bar electron-positron collider. Our results, P-tau(D*) = -0.38 +/- 0.51 (stat)(-0.16)(+0.21) (syst) and R(D*) = 0.270 +/- 0.035 (stat)(- 0.025)(+0.028) (syst), are consistent with the theoretical predictions of the standard model.

    We report the first measurement of the T-odd moments in the decay D-0 -&gt; K-S(0) pi + pi(-)pi(0) from a data sample corresponding to an integrated luminosity of 966 fb(-1) collected by the Belle experiment at the KEKB asymmetric-energy e(+)e(-) collider. From these moments we determine the CP-violation-sensitive asymmetry a(CP)(T-odd) = [-0.28 +/- 1.38 (stat.)(-0.76)(+0.23) (syst.)] x 10(-3) , which is consistent with no CP violation. In addition, we perform a(CP)(T-odd) measurements in different regions of the D-0 -&gt; K-S(0) pi + pi(-)pi(0) phase space; these are also consistent with no CP violation.

    We present a measurement of angular observables and a test of lepton flavor universality in the B -&gt; K(+)l(+)l(-) decay, where l is either e or mu. The analysis is performed on a data sample corresponding to an integrated luminosity of 711 fb(-1) containing 772 x 10(6) B (B) over bar pairs, collected at the Upsilon(4S) resonance with the Belle detector at the asymmetric-energy e(+)e(-) collider KEKB. The result is consistent with standard model (SM) expectations, where the largest discrepancy from a SM prediction is observed in the muon modes with a local significance of 2.6 sigma.

    We report the result from the first search for D-0 decays to invisible final states. The analysis is performed on a data sample of 924 fb(-1) collected at and near the gamma(4S) and gamma(5S) resonances with the Belle detector at the KEKB asymmetric-energy e(|) e(-) collider. The absolute branching fraction is determined using an inclusive D-0 sample, obtained by fully reconstructing the rest of the particle system including the other charmed particle. No significant signal yield is observed and an upper limit of 9.4 x 10(-5) is set on the branching fraction of D-0 to invisible final states at 90% confidence level.

    We report the first search for the J(PC) = 0(--) glueball in Upsilon(1S) and Upsilon(2S) decays with data samples of (102 +/- 2) x 10(6) and (158 +/- 4) x 10(6) events, respectively, collected with the Belle detector. No significant signals are observed in any of the proposed production modes, and the 90% credibility level upper limits on their branching fractions in Upsilon(1S) and Upsilon(2S) decays are obtained. The inclusive branching fractions of the Upsilon(1S) and Upsilon(2S) decays into final states with chi(c1) are measured to be B(Upsilon(1S) -&gt; chi(c1) + anything) = (1.90 +/- 0.43(stat) +/- 0.14(syst) x 10(-4) with an improved precision over prior measurements and B Upsilon(2S) -&gt; chi(c1) + anything) = (2.24 +/- 0.44(stat) +/- 0.20(syst) x 10(-4) for the first time.

    We report the first observation of the radiative charm decay D-0 -&gt; rho(0)gamma and the first search for CP violation in decays D-0 -&gt; rho(0)gamma, phi gamma, and (K) over bar (*0)(892)gamma, using a data sample of 943 fb(-1) collected with the Belle detector at the KEKB asymmetric-energy e(+)e(-) collider. The branching fraction is measured to be B(D-0 -&gt; rho(0)gamma) = (1.77 +/- 0.30 +/- 0.07) x 10(-5), where the first uncertainty is statistical and the second is systematic. The obtained CP asymmetries A(CP)(D-0 -&gt;rho(0)gamma) = +0.056 +/- 0.152 +/- 0.006, A(CP)(D-0 -&gt; phi gamma) = -0.094 +/- 0.066 +/- 0.001, and A(CP)(D-0 -&gt; (K) over bar (*0) gamma = -0.003 +/- 0.020 +/- 0.000 are consistent with no CP violation. We also present an improved measurement of the branching fractions B(D-0 -&gt; phi gamma) = (2.76 +/- 0.19 +/- 0.10) x 10(-5) and B(D-0 -&gt; (K) over bar (*0) gamma = (4.66 +/- 0.21 +/- 0.21) x 10(-4).

    We report a measurement of the ratio R(D*) = B((B) over bar (0) -&gt; D*(+)tau(-)(nu) over bar (tau))/B((B) over bar (0) -&gt; D*(+)l(-)(nu) over bar (l))where l denotes an electron or a muon. The results are based on a data sample containing 772 x 10(6) B (B) over bar pairs recorded at the Upsilon(4S) resonance with the Belle detector at the KEKB e(+)e(-) collider. We select a sample of B-0(B) over bar (0) pairs by reconstructing both B mesons in semileptonic decays to D*(-/+)l(+/-). We measure R(D*) = 0.302 +/- 0.030(stat) +/- 0.011(syst), which is within 1.6 sigma of the Standard Model theoretical expectation, where the standard deviation sigma includes systematic uncertainties. We use this measurement to constrain several scenarios of new physics in a model-independent approach.

    deviations above zero, which provides the first evidence for the decay $B^{0}

    Using a data sample of 980 fb(-1) of e(+)e(-) annihilation data taken with the Belle detector operating at the KEKB asymmetric-energy e(+)e(-) collider, we report the results of a study of excited Xi(c) states that decay, via the emission of photons and/or charged pions, into Xi(0)(c) or Xi(+)(c) ground state charmed-strange baryons. We present new measurements of the masses of all members of the Xi(0)(c), Xi(c)(2645), Xi(c)(2790), Xi(c)(2815), and Xi(c)(2980) isodoublets, measurements of the intrinsic widths of those that decay strongly, and evidence of previously unknown transitions.

    We report a measurement of the CP-violation parameter phi(1) obtained in a time-dependent analysis of B-0 -&gt; (D) over bar(*)(0)h(0) decays followed by (D) over bar (0) -&gt; K-S(0)pi(+)pi decay. A model-independent measurement is performed using the binned Dalitz plot technique. The measured value is phi(1) = 11.7 degrees +/- 7.8 degrees(stat) +/- 2.1 degrees (syst). Treating sin 2 phi(1) and cos 2 phi(1) as independent parameters, we obtain sin 2 phi(1) = 0.43 +/- 0.27(stat) +/- 0.08(syst) and cos 2 phi(1) = 1.06 +/- 0.33(stat)(-0.15)(+0.21)(syst). The results are obtained with a full data sample of 772 x 10(6)B (B) over bar pairs collected near the Upsilon(4S) resonance with the Belle detector at the KEKB asymmetric-energy e(+)e(-) collider.

    Using data collected with the Belle detector at the KEKB asymmetric-energy e(+)e(-) collider, we measure the energy dependence of the e(+)e(-) -&gt; h(b)(nP)pi(+)pi(-) (n = 1, 2) cross sections from thresholds up to 11.02 GeV. We find clear gamma(10860) and gamma(11020) peaks with little or no continuum contribution. We study the resonant substructure of the gamma(11020) -&gt; h(b)(nP)pi(+)pi(_) transitions and find evidence that they proceed entirely via the intermediate isovector states Z(b)(10610) and Z(b)(10650). The relative fraction of these states is loosely constrained by the current data: The hypothesis that only Z(b)(10610) is produced is excluded at the level of 3.3 standard deviations, while the hypothesis that only Z(b)(10650) is produced is not excluded at a significant level.

    We report the discovery of Xi(c)(3055)(0), observed by its decay into the final-state Lambda D-0, and present the first observation and evidence of the decays of Xi(c)(3055)(+) and Xi(c)(3080)(+) into Lambda D+. We also perform a combined analysis of the Lambda D+ with the Sigma K-++(c)- and Sigma(c)*K-++(-) decay modes to measure the ratios of branching fractions, masses and widths with improved accuracy. We measure the ratios of branching fractions B(Xi(c)(3055)(+) -&gt; Lambda D+)/B(Xi(c)(3055)(+) -&gt; Sigma(++)(c) K-) = 5.09 +/- 1.01 +/- 0.76, B(Xi(c)(3080)(+) -&gt; Lambda D+)/B(Xi(c)(3080)(+) -&gt; Sigma K-++(c)-) = 1.29 +/- 0.30 +/- 0.15, and B(Xi(c)(3080)(+) -&gt; Sigma(c)*K-++(-))/B(Xi(c)(3080)(+) -&gt; Sigma K-++(c)-) = 1.07 +/- 0.27 +/- 0.04, where the uncertainties are statistical and systematic. The analysis is performed using a 980 fb(-1) data sample collected with the Belle detector at the KEKB asymmetric-energy e(+)e(-) collider.

The results are obtained from a 711 fb(-1) data sample that corresponds to 772 x 10(6) B (B) over bar pairs, collected at the Upsilon(4S) resonance with the Belle detector at the KEKB e(+)e(-) collider. One B meson is fully reconstructed in a hadronic mode to determine the momentum of the lepton of the signal decay in the rest frame of the recoiling partner B meson. We find no evidence of a signal and set upper limits on the order of 10(-6).

No signal is observed, and we set an upper limit on the branching fraction of B(B-0 -&gt; phi gamma) &lt; 1.0 x 10(-7) at the 90% confidence level. This is the most stringent limit on this decay mode to date.

    The process gamma gamma -&gt; p (p) over barK(+)K(-) and its intermediate processes are measured for the first time using a 980 fb(-1) data sample collected with the Belle detector at the KEKB asymmetric-energy e(+)e(-) collider. The production of p (p) over barK(+)K(-) and a Lambda(1520)(0) ((Lambda) over bar (1520)(0)) signal in the pK(-) ((p) over barK(+)) invariant mass spectrum are clearly observed. However, no evidence for an exotic baryon near 1540 MeV/c(2), denoted as Theta(1540)(0) ((Theta) over bar (1540)(0)) or Theta(1540)(++) (Theta(1540)(--)), is seen in the pK(-) ((p) over barK(+)) or pK(+) ((p) over barK(-)) invariant mass spectra. Cross sections for gamma gamma -&gt; p (p) over barK(+)K(-), Lambda(1520)(0)(p) over barK(+) + c.c. and the products sigma(gamma gamma -&gt; Theta(1540)(0)(p) over barK(+) + c.c.)B(Theta(1540)(0) -&gt; pK(-)) and sigma(gamma gamma -&gt; Theta(1540)(++)(p) over barK(-) + c.c.)B(Theta(1540)(++) -&gt; pK(+)) are measured. We also determine upper limits on the products of the chi(c0) and chi(c2) two-photon decay widths and their branching fractions to p (p) over barK(+)K(-) at the 90% credibility level.

    The branching fractions of the Upsilon(1S) inclusive decays into final states with a J/psi or psi(2S) are measured with improved precision to be B Upsilon(1S) -&gt; J/psi + anything = (5.25 +/- 0.13(stat) +/- 0.25(syst) x 10(-4) and B Upsilon(1S) -&gt; psi(2S) + anything = (1.23 +/- 0.17(stat) +/- 0.11(syst)) x 10(-4). The first search for Upsilon(1S) decays into XYZ states that decay into a J/psi or a psi(2S) plus one or two charged tracks yields no significant signals for XYZ states in any of the examined decay modes, and upper limits on their production rates in Upsilon(1S) inclusive decays are determined.

    We report the first observation of the decay Lambda(+)(c) -&gt; pK(+)pi(-) using a 980 fb(-1) data sample collected by the Belle detector at the KEKB asymmetric-energy e(+)e(-) collider. This is the first observation of a doubly Cabibbo-suppressed decay of a charmed baryon. We measure the branching ratio of this decay with respect to its Cabibbo-favored counterpart to be B(Lambda(+)(c) -&gt; pK(+)pi(-))/B(Lambda(+)(c) -&gt; pK(-)pi(+)) = (2.35 +/- 0.27 +/- 0.21) x 10(-3), where the uncertainties are statistical and systematic, respectively.

We measure Born cross sections for the three-body production of sigma(e(+)e(-) -&gt; [B (B) over bar* + c.c.](+/-)pi(-/+)) = [17.4 +/- 1.6(stat) +/- 1.9(syst)]pb and sigma(e(+)e(-) -&gt; [B*(B) over bar*](+/-)pi(-/+)) = [8.75 +/- 1.15(stat) +/- 1.04(syst)] pb and set a 90% C.L. upper limit of sigma(e(+)e(-) -&gt; [B (B) over bar](+/-)pi(-/+)) &lt; 2.9 pb. The results are based on a 121.4 fb(-1) data sample collected with the Belle detector at a center-of-mass energy near the Upsilon(10860) peak.

    We measure the decay B-s(0) -&gt; K-0(K) over bar (0) using data collected at the Upsilon(5S) resonance with the Belle detector at the KEKB e(+)e(-) collider. The data sample used corresponds to an integrated luminosity of 121.4 fb(-1). We measure a branching fraction beta(B-s(0) -&gt; K-0(K) over bar (0)) = [19.6(-5.1)(+5.8)(stat) +/- 1.0(syst) +/- 2.0(N-Bs0 (B) over bar s0)] x 10(-6) with a significance of 5.1 standard deviations. This measurement constitutes the first observation of this decay.

    We report a measurement of the amplitude ratio r(S) of B-0 -&gt; (DK)-K-0*(0) and B-0 -&gt; (D) over bar K-0*(0) decays with a Dalitz analysis of D -&gt; K-S(0)pi(+)pi(-) decays, for the first time using a model-independent method. We set an upper limit r(S) &lt; 0.87 at the 68% confidence level, using the full data sample of 711 fb(-1) corresponding to 772 x 10(6) B&lt;(B)over bar&gt; pairs collected at the Upsilon(4S) resonance with the Belle detector at the KEKB e(+)e(-) collider. This result is obtained from observables x(-) = +0.4(-0.6-0.1)(+1.0+0.0) +/- 0.0, y(-) = -0.6(-1.0-0.0)(+0.8+0.1) +/- 0.1, x(+) = +0.1(-0.4-0.1)(+0.7+0.0) +/- 0.1, and y(+) = +0.3(-0.8-0.1)(+0.5+0.0) +/- 0.1, where x(+/-) = r(S) cos(delta(S) +/- phi(3)), y(+/-) = r(S) sin(delta(S) +/- phi(3)), and phi(3) (delta(S)) is the weak (strong) phase difference between B-0 -&gt; D0K*(0) and B-0 -&gt; (D) over bar K-0*(0).

    We report inclusive and exclusive measurements for chi(c1) and chi(c2) production in B decays. We measure B(B -&gt; chi X-c1) = (3.03 +/- 0.05 (stat) +/- 0.24(syst)) x 10(-3) and B(B -&gt; chi X-c2) = (0.70 +/- 0.06 (stat) +/- 0.10(syst)) x 10(-3). For the first time, chi(c2) production in exclusive B decays in the modes B-0 -&gt; chi(c2) pi K--(+) and B-0 -&gt; chi(c2) pi(-)pi K-+(+) has been observed, along with first evidence for the B-0 -&gt; chi(c2) pi K--(s)0 decay mode. For chi c1 production, we report the first observation in the B+ -&gt; chi(c1) pi(-)pi K-+(+), B-0 -&gt; chi(c1) pi(-)pi K-+(s)0 and B-0 -&gt; chi(c1) pi(-)pi K-+(+) decay modes. Using these decay modes, we observe a difference in the production mechanism of chi(c2) in comparison to chi(c1) in B decays. In addition, we report searches for X(3872) and chi(c1) (2P) in the B+ -&gt; (chi(c1) pi(+)pi(-))K+ decay mode. The reported results use 772 x 10(6) B (B) over bar events collected at the Upsilon(4S) resonance with the Belle detector at the KEKB asymmetric-energy e(+)e(-) collider.

    We search for the rare radiative decay D-0 -&gt; gamma gamma using a data sample with an integrated luminosity of 832 fb(-1) recorded by the Belle detector at the KEKB e(+)e(-) asymmetric-energy collider. We find no statistically significant signal and set an upper limit on the branching fraction of B(D-0 -&gt; gamma gamma) &lt; 8.5 x 10(-7) at 90% confidence level. This is the most restrictive limit on the decay channel to date.

    We present a determination of the magnitude of the Cabibbo-Kobayashi-Maskawa matrix element vertical bar V-cb vertical bar using the decay B -&gt; Dl nu(l) (l = e,mu) based on 711 fb(-1) of e(+)e(-) -&gt; Upsilon(4S) data recorded by the Belle detector and containing 772 x 10(6) B (B) over bar pairs. One B meson in the event is fully reconstructed in a hadronic decay mode, while the other, on the signal side, is partially reconstructed from a charged lepton and either a D+ or D-0 meson in a total of 23 hadronic decay modes. The isospin-averaged branching fraction of the decay B -&gt; Dl nu(l) is found to be B(B-0 -&gt; D(-)l(vertical bar)nu(l)) = (2.31 +/- 0.03(stat) +/- 0.11(syst))%. Analyzing the differential decay rate as a function of the hadronic recoil with the parametrization of Caprini, Lellouch, and Neubert and using the form-factor prediction G(1) = 1.0541 +/- 0.0083 calculated by FNAL/MILC, we obtain eta(EW)vertical bar V-cb vertical bar = (40.12 +/- 1.34) x 10(-3), where eta(EW) is the electroweak correction factor. Alternatively, assuming the model-independent form-factor parametrization of Boyd, Grinstein, and Lebed and using lattice QCD data from the FNAL/MILC and HPQCD collaborations, we find eta(EW)vertical bar V-cb vertical bar = (41.10 +/- 1.14) x 10(-3).

    We report a measurement of the differential cross section of pi(0) pair production in single-tag two-photon collisions, gamma*gamma -&gt; pi(0) pi(0), in e(+) e(-) scattering. The cross section is measured for Q(2) up to 30 GeV2, where Q(2) is the negative of the invariant mass squared of the tagged photon, in the kinematic range 0.5 GeV &lt; W &lt; 2.1 GeV and vertical bar cos theta*vertical bar &lt; 1.0 for the total energy and pion scattering angle, respectively, in the gamma*gamma center-of-mass system. The results are based on a data sample of 759 fb(-1) collected with the Belle detector at the KEKB asymmetric-energy e(+) e(-) collider. The transition form factor of the f(0)(980) and that of the f(2)(1270) with the helicity-0, -1, and -2 components separately are measured for the first time and are compared with theoretical calculations.

    We report the first measurement of the lepton forward-backward asymmetry A(FB) as a function of the squared four-momentum of the dilepton system, q(2), for the electroweak penguin process B -&gt; X(s)l(+)l(-) with a sum of exclusive final states, where l is an electron or a muon and X-s is a hadronic recoil system with an s quark. The results are based on a data sample containing 772 x 10(6) B (B) over bar pairs recorded at the gamma (4S) resonance with the Belle detector at the KEKB e(+)e(-) collider. A(FB) for the inclusive B -&gt; X(s)l(+)l(-) is extrapolated from the sum of 10 exclusive X-s states whose invariant mass is less than 2 GeV/c(2). For q(2) &gt; 10.2 GeV2/c(2), A(FB) &lt; 0 is excluded at the 2.3 sigma level, where sigma is the standard deviation. For q(2) &lt; 4.3 GeV2/c(2), the result is within 1.8 sigma of the standard model theoretical expectation.

    We present a measurement of the branching fraction and the longitudinal polarization fraction of B-0 -&gt; rho(+)rho(-) decays, as well as the time-dependent CP violating parameters in decays into longitudinally polarized rho(+)rho(-) pairs with Belle's final data set of 772 x 10(6) B (B) over bar pairs, at the Upsilon(4S) resonance, collected at the asymmetric-energy e(+)e(-) collider KEKB. We obtain B(B-0 -&gt; rho(+)rho(-)) = (28.3 +/- 1.5(stat) +/- 1.5(syst)) x 10(-6), f(L) = 0.988 +/- 0.012(stat) +/- 0.023(syst), A(CP) = 0.00 +/- 0.10(stat) +/- 0.06(syst), S-CP = -0.13 +/- 0.15(stat) +/- 0.05(syst). We perform an isospin analysis to constrain the Cabibbo-Kobayashi-Maskawa angle phi(2) and obtain two solutions with phi(2) = (93.7 +/- 10.6)degrees, being most compatible with other Standard-Model based fits to the data.

    We search for the process B-0 -&gt; pi(-) tau(+)nu(tau) using the full Belle data set of 711 fb(-1), corresponding to 772 x 10(6)B (B) over bar pairs, collected at the gamma (4S) resonance with the Belle detector at the KEKB asymmetric-energy e(+)e(-) collider. We reconstruct one B meson in a hadronic decay and search for the B-0 -&gt; pi(-)tau(+)nu(tau) process in the remainder of the event. No significant signal is observed and an upper limit of B(B-0 -&gt; pi(-) tau(+)nu(tau)) &lt; 2.5 x 10(-4) is obtained at the 90% confidence level.

    We report an improved measurement of D-0-(D) over bar (0) mixing and a search for CP violation in D-0 decays to CP-even final states K+K- and pi(+)pi(-). The measurement is based on the final Belle data sample of 976 fb(-1). The results are y(CP) = (1.11 +/- 0.22 +/- 0.09)% and A(Gamma) =(-0.03 +/- 0.20 +/- 0.07)%, where the first uncertainty is statistical and the second is systematic. (C) 2015 The Authors.

    We report new measurements of the total cross sections for e(+)e(-) -&gt; Upsilon(nS)pi(+)pi(-) (n = 1, 2, 3) and e(+)e(-) -&gt; b (b) over bar from a high-luminosity fine scan of the region root s = 10.63-11.05 GeV with the Belle detector. We observe that the Upsilon(nS)pi(+)pi(-) spectra have little or no nonresonant component and extract from them the masses and widths of Upsilon(10860) and Upsilon(11020) and their relative phase. We find M-10860 = (10891.1 +/- 3.2(-1.7)(+0.6)) MeV/c(2) and Gamma(10860) = (53.7(-5.6)(-5.4)(+7.1)(+1.3)) MeV and report first measurements M-11020 = (1098(-2.5)(-2.1)(+6.4)(+9.0)) MeV/c(2), Gamma(11020) = (61(-19)(-20)(+9)(+2)) MeV, and phi(11020) - phi 10860 = (-1.0 +/- 0.4(-0.1)(+1.4)) rad.

    We search for the rare radiative decay $D^0\to\gamma\gamma$ using a data
    sample with an integrated luminosity of $832{\rm fb^{-1 } }$ recorded by the
    Belle detector at the KEKB $e^+e^-$ asymmetric-energy collider. We find no
    statistically significant signal and set an upper limit on the branching
    fraction of ${\cal B}(D^0\to\gamma\gamma)<8.5\times10^{-7}$ at $90\%$
    confidence level. This is the most restrictive limit on the decay channel to
    date.

    © 2015 American Physical Society. We report the first double differential cross sections of two charged pions and kaons (e+e-→hhX) in electron-positron annihilation as a function of the fractional energies of the two hadrons for any charge and hadron combination. The dependence of these dihadron cross sections on the topology (same, opposite hemisphere or anywhere) is also studied with the help of the event shape variable thrust and its axis. The ratios of these dihadron cross sections for different charges and hadron combinations directly shed light on the contributing fragmentation functions. For example, we find that the ratio of same-sign pion pairs over opposite-sign pion pairs drops toward higher fractional energies where disfavored fragmentation is expected to be suppressed. These dihadron results are obtained from a 655 fb-1 data sample collected near the (4S) resonance with the Belle detector at the KEKB asymmetric-energy e+e- collider. Extending the previously published single-pion and single-kaon cross sections, single-proton (e+e-→pX) cross sections are extracted from a 159 fb-1 data subsample.

    We report the first observation of the decays B-0 -&gt; p (Lambda) over barD(*)(-). The data sample of 711 fb(-1) used in this analysis corresponds to 772 x 10(6) B (B) over bar pairs, collected at the Upsilon(4S) resonance by the Belle detector at the KEKB asymmetric-energy e(+)e(-) collider. We observe 19.8 sigma and 10.8 sigma excesses of events for the two decay modes and measure the branching fractions of B-0 -&gt; p (Lambda) over barD(-) and B-0 -&gt; p (Lambda) over barD*(-) to be (25.1 +/- 2.6 +/- 3.5) x 10(-6) and (33.6 +/- 6.3 +/- 4.4) x 10(-6), respectively, where the first uncertainties are statistical and the second are systematic. These results are not compatible with the predictions based on the generalized factorization approach. In addition, a threshold enhancement in the dibaryon (p (Lambda) over bar) system is observed, consistent with that observed in similar B decays.

We report a measurement of the branching fraction ratios R(D(∗)) of B¯→D(∗)τ-ν¯τ relative to B¯→D(∗) -ν¯ (where =e or μ) using the full Belle data sample of 772×106BB¯ pairs collected at the (4S) resonance with the Belle detector at the KEKB asymmetric-energy e+e- collider. The measured values are R(D)=0.375±0.064(stat)±0.026(syst) and R(D∗)=0.293±0.038(stat)±0.015(syst). The analysis uses hadronic reconstruction of the tag-side B meson and purely leptonic τ decays. The results are consistent with earlier measurements and do not show a significant deviation from the standard model prediction.

    We present a measurement of the branching fraction and the longitudinal
    polarization fraction of $B^{0}\rightarrow\rho^+\rho^-$ decays, as well as the
    time-dependent $CP$ violating parameters in decays into longitudinally
    polarized $\rho^{+}\rho^{-}$ pairs with Belle's final data set of $772\times
    10^6$ $B\bar{B}$ pairs, at the $\Upsilon(4S)$ resonance, collected at the
    asymmetric-energy $e^+ e^-$ collider KEKB. We obtain ${\cal B}(B^0 \rightarrow
    \rho^+ \rho^-)=(28.3\pm 1.5\;(\rm stat) \pm 1.5\;(\rm syst))\times 10^{-6}$,
    $f_L = 0.988\pm 0.012\;(\rm stat ) \pm0.023\;(\rm syst)$, ${\cal A}_{CP} =

    -0.13\pm0.15\;(\rm stat ) \pm0.05\;(\rm syst).$ We perform an isospin analysis
    to constrain the CKM angle $\phi_2$ and obtain two solutions with

    We report a measurement of the branching fraction ratios R(D)(()*()) of (B) over bar -&gt; D-(*())tau(-)(nu) over bar (tau) relative to (B) over bar -&gt; D-(*())l(-)(nu) over barl (where l = e or mu) using the full Belle data sample of 772 x 10(6)B (B) over bar pairs collected at the Upsilon(4S) resonance with the Belle detector at the KEKB asymmetric-energy e(+)e(-) collider. The measured values are R(D) = 0.375 +/- 0.064(stat) +/- 0.026(syst) and R(D*) = 0.293 +/- 0.038 (stat) +/- 0.015 (syst). The analysis uses hadronic reconstruction of the tag-side B meson and purely leptonic t decays. The results are consistent with earlier measurements and do not show a significant deviation from the standard model prediction.

    We report a measurement of the branching fraction of B+ -&gt; tau(+) nu(tau) decays using a data sample of 772 x 10(6) B (B) over bar pairs, collected at the Upsilon(4S) resonance with the Belle detector at the KEKB asymmetric-energy e(+)e(-) collider. We reconstruct the accompanying B meson in a semileptonic decay and detect the recoiling B candidate in the decay channel B+ -&gt; tau(+) nu(tau). We obtain a branching fraction of B(B+ -&gt; tau(+) nu(tau)) = [1.25 +/- 0.28(stat.) +/- 0.27(syst.)] x 10-(4). This result is in good agreement with previous measurements and the expectation from the calculation based on the Standard Model.

    We report a measurement of the time-dependent CP asymmetry of (B) over bar (0) -&gt; D(CP)((*))h(0) decays, where the light neutral hadron h(0) is a pi(0), eta , or omega meson, and the neutral D meson is reconstructed in the CP eigenstates K+K-, K-S(0)pi(0) or K-S(0)omega. The measurement is performed combining the final data samples collected at the Upsilon(4S) resonance by the BABAR and Belle experiments at the asymmetric-energy B factories PEP-II at SLAC and KEKB at KEK, respectively. The data samples contain (471 +/- 3) x 10(6) B (B) over bar pairs recorded by the BABAR detector and (772 +/- 11) x 10(6) B (B) over bar pairs recorded by the Belle detector. We measure the CP asymmetry parameters -eta S-f = +0.66 +/- 0.10(stat) +/- 0.06(syst) and C = -0.02 +/- 0.07(stat) +/- 0.03(syst). These results correspond to the first observation of CP violation in (B) over bar (0) -&gt; D(CP)((*))h(0) decays. The hypothesis of no mixing-induced CP violation is excluded in these decays at the level of 5.4 standard deviations.

    The process e(+)e(-) -&gt; gamma chi(cJ) (J = 1, 2) is studied via initial state radiation using 980 fb(-1) of data at and around the Gamma(nS) (n = 1, 2, 3, 4, 5) resonances collected with the Belle detector at the KEKB asymmetricenergy e(+)e(-) collider. No significant signal is observed except from psi(2S) decays. Upper limits on the cross sections between root s = 3.80 and 5.56 GeV are determined at the 90% credibility level, which range from a few pb to a few tens of pb. We also set upper limits on the decay rate of the vector charmonium [psi(4040), psi(4160), and psi(4415)] and charmoniumlike [Y(4260), Y(4360), and Y(4660)] states to gamma chi(cJ).

    We report a search for the charmless hadronic decay B-0 -&gt; eta pi(0) with a data sample corresponding to an integrated luminosity of 694 fb(-1) containing 753 x 10(6) BB pairs. The data were collected by the Belle experiment running on the Upsilon(4S) resonance at the KEKB e(+)e(-) collider. We measure a branching fraction B(B-0 &gt; eta pi(0)) = (4.1(-1.5-0.7)(+1.75+0.5)) x 10(-7), where the first unceminty is statistical and the second is systematic. Our measur
