    We present GFlaT, a new algorithm that uses a graph-neural-network to determine the flavor of neutral B mesons produced in ϒ(4S) decays. It improves previous algorithms by using the information from all charged final-state particles and the relations between them. We evaluate its performance using B decays to flavor-specific hadronic final states reconstructed in a 362  fb−1 sample of electron-positron collisions collected at the ϒ(4S) resonance with the Belle II detector at the SuperKEKB collider. We achieve an effective tagging efficiency of (37.40±0.43±0.36%), where the first uncertainty is statistical and the second systematic, which is 18% better than the previous Belle II algorithm. Demonstrating the algorithm, we use B0→J/ψKS0 decays to measure the mixing-induced and direct CP violation parameters, S=(0.724±0.035±0.009) and C=(−0.035±0.026±0.029).

    Abstract

    We measure CP asymmetries and branching-fraction ratios for B<sup>±</sup>→ DK<sup>±</sup> and Dπ<sup>±</sup> decays with D →$$ {K}_{\textrm{S } }^0 $$K<sup>±</sup>π<sup>∓</sup>, where D is a superposition of D<sup>0</sup> and $$ \overline{D} $$<sup>0</sup>. We use the full data set of the Belle experiment, containing 772 × 10<sup>6</sup>$$ B\overline{B} $$ pairs, and data from the Belle II experiment, containing 387 × 10<sup>6</sup>$$ B\overline{B} $$ pairs, both collected in electron-positron collisions at the Υ(4S) resonance. Our results provide model-independent information on the unitarity triangle angle ϕ<sub>3</sub>.

    We report measurements of the branching fraction and CP asymmetry in B0→π0π0 decays reconstructed at Belle II in an electron-positron collision sample containing 198×106 BB¯ pairs. We measure a branching fraction B(B0→π0π0)=(1.38±0.27±0.22)×10-6 and a CP asymmetry ACP(B0→π0π0)=0.14±0.46±0.07, where the first uncertainty is statistical and the second is systematic.

    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 measure the branching fraction for the Cabibbo-suppressed decay D0→KS0KS0π+π- and search for CP violation via a measurement of the CP asymmetry ACP as well as the T-odd triple-product asymmetry aCPT. We use 922 fb-1 of data recorded by the Belle experiment, which ran at the KEKB asymmetric-energy e+e- collider. The branching fraction is measured relative to the Cabibbo-favored normalization channel D0→KS0π+π-; the result is B(D0→KS0KS0π+π-)=[4.79±0.08(stat)±0.10(syst)±0.31(norm)]×10-4, where the first uncertainty is statistical, the second is systematic, and the third is from uncertainty in the normalization channel. We also measure ACP=[-2.51±1.44(stat)-0.10+0.11(syst)]%, and aCPT=[-1.95±1.42(stat)-0.12+0.14(syst)]%. These results show no evidence of CP violation.

    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 a study of a singly Cabibbo-suppressed decay Λc+→pKS0KS0 and a Cabibbo-favored decay Λc+→pKS0η based on 980 fb-1 of data collected by the Belle detector, operating at the KEKB energy-asymmetric e+e- collider. We measure their branching fractions relative to Λc+→pKS0: B(Λc+→pKS0KS0)/B(Λc+→pKS0)=(1.48±0.08±0.04)×10-2 and B(Λc+→pKS0η)/B(Λc+→pKS0)=(2.73±0.06±0.13)×10-1. Combining with the world average B(Λc+→pKS0), we have the absolute branching fractions, B(Λc+→pKS0KS0)=(2.35±0.12±0.07±0.12)×10-4 and B(Λc+→pKS0η)=(4.35±0.10±0.20±0.22)×10-3. The first and second uncertainties are statistical and systematic, respectively, while the third ones arise from the uncertainty on B(Λc+→pKS0). The mode Λc+→pKS0KS0 is observed for the first time and has a statistical significance of >10σ. The branching fraction of Λc+→pKS0η has been measured with a threefold improvement in precision over previous results and is found to be consistent with the world average.

    We present the first search for the weak radiative decays Λc+→ς+γ and Ξc0→Ξ0γ using a data sample of 980 fb-1 collected by the Belle detector operating at the KEKB asymmetric-energy e+e- collider. There are no evident Λc+→ς+γ or Ξc0→Ξ0γ signals. Taking the decays Λc+→pK-π+ and Ξc0→Ξ-π+ as normalization channels, the upper limits at 90% credibility level on the ratios of branching fractions B(Λc+→ς+γ)/B(Λc+→pK-π+)<4.0×10-3 and B(Ξc0→Ξ0γ)/B(Ξc0→Ξ-π+)<1.2×10-2 are determined. We obtain the upper limits at 90% credibility level on the absolute branching fractions B(Λc+→ς+γ)<2.6×10-4 and B(Ξc0→Ξ0γ)<1.8×10-4.

    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.

    Abstract

    We report on new flavor tagging algorithms developed to determine the quark-flavor content of bottom ("Image missing") mesons at Belle II. The algorithms provide essential inputs for measurements of quark-flavor mixing and charge-parity violation. We validate and evaluate the performance of the algorithms using hadronic "Image missing" decays with flavor-specific final states reconstructed in a data set corresponding to an integrated luminosity of 62.8 fb$$^{-1}$$, collected at the "Equation missing" resonance with the Belle II detector at the SuperKEKB collider. We measure the total effective tagging efficiency to be $$\begin{aligned} \varepsilon _\mathrm{eff} = \big (30.0 \pm 1.2(\text {stat}) \pm 0.4(\text {syst})\big )\% \end{aligned}$$for a category-based algorithm and $$\begin{aligned} \varepsilon _\mathrm{eff} = \big (28.8 \pm 1.2(\text {stat}) \pm 0.4(\text {syst})\big )\% \end{aligned}$$for a deep-learning-based algorithm.

    We present a measurement of RK∗, the branching fraction ratio B(B→K∗μ+μ-)/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 q2. The analysis is based on a data sample of 711 fb-1, containing 772×106 BB¯ events, recorded at the ϒ(4S) resonance with the Belle detector at the KEKB asymmetric-energy e+e- collider. The obtained results are consistent with standard model expectations.

    TheAerogel Ring Imaging Cherenkov (ARICH) counter serves as a particle identification device in the forward end-cap region of the Belle II spectrometer. It is capable of identifying pions and kaons with momenta up to 4 GeV c-1 by detecting Cherenkov photons emitted in the silica aerogel radiator. After the detector alignment and calibration of the probability density function, we evaluate the performance of the ARICH counter using early beam collision data. Event samples of D*+ → D0π + (D0 → K- π + ) were used to determine the π(K) efficiency and the K(π) misidentification probability. We found that the ARICH counter is capable of separating kaons from pions with an identification efficiency of 93.5 ± 0.6% at a pion misidentification probability of 10.9 ± 0.9 %. This paper describes the identification method of the counter and the evaluation of the performance during its early operation.

    In the Belle II experiment, an aerogel-based proximity focusing ring-imaging Cherenkov (ARICH) counter is used for charged particle identification (PID) in the forward end-cap region. The goal is to separate kaons from pions at above 4σ significance level for momenta up to 4 GeV/c, which is critical for the measurements of rare B decays and CP violation in B decays. Chrerenkov photons are emitted in aerogel tiles and 144-channel Hybrid Avalanche Photo Detector (HAPDs) are used as the photo-detectors. We utilize a two-layer aerogel design with different refractive indexes in a focusing configuration. In Phase 3 of the Belle II operation (from Apr. 2019), the ARICH system has been operating smoothly. The performance of particle identification with ARICH has been well validated and is in agreement with simulation.

    We report the result for a search for the leptonic decay of B+ -> mu(+)nu mu using the full Belle dataset of 711 fb(-1) of integrated luminosity at the gamma(4S) resonance. In the Standard Model leptonic B-meson decays are helicity and Cabibbo-Kobayashi-Maskawa suppressed. To maximize sensitivity an inclusive tagging approach is used to reconstruct the second B meson produced in the collision. The directional information from this second B meson is used to boost the observed mu into the signal B-meson rest frame, in which the mu has a monochromatic momentum spectrum. Though its momentum is smeared by the experimental resolution, this technique improves the analysis sensitivity considerably. Analyzing the mu momentum spectrum in this frame we find B(B+ -> mu(+)nu mu)=(5.3 +/- 2.0 +/- 0.9) x 10(-7) with a one-sided significance of 2.8 standard deviations over the background-only hypothesis. This translates to a frequentist upper limit of B(B+ -> mu(+)nu mu) < 8.6 x 10(-7) at 90% confidence level. The experimental spectrum is then used to search for a massive sterile neutrino, B+ -> mu N+, but no evidence is observed for a sterile neutrino with a mass in a range of 01.5 GeV. The determined B+ -> mu(+)nu mu branching fraction limit is further used to constrain the mass and coupling space of the type II and type III two-Higgs-doublet models.

    For efficient separation of hadrons in the forward end-cap of the Belle II spectrometer, an aerogel proximity focusing Ring Imaging Detector is installed in the high magnetic field between the central drift chamber and electromagnetic calorimeter. Cherenkov photons, emitted in the double layer aerogel radiator are expanded through the empty space and detected on the photon detector consisting of Hybrid Avalanche Photo diodes. The readout electronics working in a threshold mode records hit patterns registered during beam collisions. A particle identification algorithm based on the two dimensional extended maximum likelihood technique is used to assign probabilities for different particle hypotheses of tracks traversing the aerogel RICH detector. For efficient discrimination, the Aerogel RICH detector has to be calibrated. We present the key calibration steps used to optimize the detector performance.

    From April to July 2018, a data sample at the peak energy of the γ(4S) resonance was collected with the Belle II detector at the SuperKEKB electron-positron collider. This is the first data sample of the Belle II experiment. Using Bhabha and digamma events, we measure the integrated luminosity of the data sample to be (496.3 ± 0.3 ± 3.0) pb-1, where the first uncertainty is statistical and the second is systematic. This work provides a basis for future luminosity measurements at Belle II.

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

    We report a new measurement of the $e^+e^-\to\Upsilon(nS)\pi^+\pi^-$
    ($n=1,2,3$) 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 $M=(10752.7\pm5.9\,^{+0.7}_{-1.1})\,$MeV/$c^2$ and
    $\Gamma=(35.5^{+17.6}_{-11.3}\,^{+3.9}_{-3.3})\,$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 $e^+e^-\to\Upsilon(1S)\pi^+\pi^-$ process at the energy
    10.52 GeV, which is below the $B\bar{B}$ threshold.

    We study charmless hadronic decays of charged B mesons to the final states (KSKSK +/-)-K-0-K-0 and (KSKS0)-K-0 pi(+/-) using a 711 fb(-1) data sample that contains 772 x 10(6) B (B) over bar pairs and was collected at the Upsilon(4S) resonance with the Belle detector at the KEKB asymmetric-energy e(+)e(-) ethorne-collider. For B-+/- -> (KSKSK +/-)-K-0-K-0, the measured branching fraction and direct CP asymmetry are [10.42 +/- 0.43(stat) +/- 0.22(syst)] x 10(-6) and [+1.6 +/- 3.9(stat) +/- 0.9(syst)] %, respectively. In the absence of a statistically significant signal for B-+/- -> (KSKS0)-K-0 pi(+/-), we obtain a 90% confidence-level upper limit on its branching fraction as 8.7 x 10(-7).

    We report on the first Belle search for a light CP-odd Higgs boson, A(0), that decays into low mass dark matter, chi, in final states with a single photon and missing energy. We search for events produced via the dipion transition (sic)(2S) -> (sic)(1S)pi(+)pi(-), followed by the on-shell process (sic)(1S) -> gamma A(0) with A(0) -> chi chi, or by the off-shell process (sic)(1S) -> gamma chi chi. Utilizing a data sample of 157.3 x 10(6) (sic)(2S) decays, we find no evidence for a signal. We set limits on the branching fractions of such processes in the mass ranges M-A0 < 8.97 GeV/c(2) and M-chi < 4.44 GeV/c(2). 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/c(2).

We report a measurement of time-dependent CP violation in B0→KS0π0π0 decays using a data sample of 772×106 BB pairs collected by the Belle experiment running at the ?(4S) resonance at the KEKB e+e- collider. This decay proceeds mainly via a b→sdd "penguin" amplitude. The results are sin2φ1eff=0.92-0.31+0.27 (stat.) ±0.11 (syst.) and A=0.28±0.21 (stat.) ±0.04 (syst.), which are the most precise measurements of CP violation in this decay mode to date. The value for the CP-violating parameter sin2φ1eff is consistent with that obtained using decay modes proceeding via a b→ccs "tree" amplitude.

    We report measurements of sin 2 beta and cos 2 beta using a time-dependent Dalitz plot analysis of B-0 -> D((*))h(0) with D -> K-S(0)pi(+)pi(-) decays, where the light unflavored and neutral hadron h(0) is a pi(0),eta, or omega meson. The analysis uses a combination of the final data sets of the BABAR and Belle experiments containing 471 x 10(6) and 772 x 10(6) B (B) over bar pairs collected at the gamma(4S) resonance at the asymmetric-energy B factories PEP-II at SLAC and KEKB at KEK, respectively. We measure sin 2 beta = 0.80 +/- 0.14(stat) +/- 0.06(syst) +/- 0.03(model) and cos 2 beta = 0.91 +/- 0.22(stat) +/- 0.09(syst) +/- 0.07(model). The result for the direct measurement of the angle is beta = (22.5 +/- 4.4(stat) +/- 1.2(syst) +/- 0.6(model))degrees. The last quoted uncertainties are due to the composition of the D-0 -> K-S(0)pi(+)pi(-) decay amplitude model, which is newly established by a Dalitz plot amplitude analysis of a high-statistics e(+) e(-) -> c (c) over bar data sample as part of this analysis. We find the first evidence for cos 2 beta > 0 at the level of 3.7 standard deviations. The measurement excludes the trigonometric multifold solution pi/2 - beta = (68.1 +/- 0.7)degrees at the level of 7.3 standard deviations and therefore resolves an ambiguity in the determination of the apex of the CKM Unitarity Triangle. The hypothesis of beta = 0 degrees is ruled out at the level of 5.1 standard deviations, and thus CP violation is observed in B-0 -> D-(*) h(0) decays. The measurement assumes no direct CP violation in B-0 -> D-(*) h(0) decays.

    We present first evidence that the cosine of the CP-violating weak phase 2 beta is positive, and hence exclude trigonometric multifold solutions of the Cabibbo-Kobayashi-Maskawa (CKM) Unitarity Triangle using a time-dependent Dalitz plot analysis of B-0 -> D-(*) h(0) with D -> K-S(0)pi(+)pi(-) decays, where h(0) is an element of {pi(0), eta, omega} 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 (sic)(4S) resonance 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. The results of the measurement are sin 2 beta = 0.80 +/- 0.14 (stat) +/- 0.06 (syst) +/- 0.03 (model) and cos 2 beta = 0.91 +/- 0.22(stat) +/- 0.09 (syst) +/- 0.07(model). The result for the direct measurement of the angle beta of the CKM Unitarity Triangle is beta = [22.5 +/- 4.4 (stat) +/- 1.2 (syst) +/- 0.6(model)]degrees. The measurement assumes no direct CP violation in B-0 -> D-(*) h(0) decays. The quoted model uncertainties are due to the composition of the D-0 -> K-S(0)pi(+)pi(-) decay amplitude model, which is newly established by performing a Dalitz plot amplitude analysis using a high-statistics e(+)e(-) -> c (c) over bar data sample. CP violation is observed in B-0 -> D-(*) h(0) decays at the level of 5.1 standard deviations. The significance for cos 2 beta > 0 is 3.7 standard deviations. The trigonometric multifold solution pi/2 - beta = (68.1 +/- 0.7)degrees 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.

    We report the first observation of the doubly-strange baryon $\Xi(1620)^0$ in
    its decay to $\Xi^-\pi^+$ via $\Xi_c^+ \rightarrow \Xi^- \pi^+ \pi^+$ decays
    based on a $980\,{\rm fb}^{-1}$ 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 $\pm$ 6.0 (stat) $^{+5.9}_{-3.5}$ (syst)~MeV$/c^2$ and
    59.9 $\pm$ 4.8 (stat) $^{+2.8}_{-3.0}$ (syst)~MeV, respectively. We obtain
    4.0$\sigma$ evidence of the $\Xi(1690)^0$ with the same data sample. These
    results shed light on the structure of hyperon resonances with strangeness
    $S=-2$.

    © 2018 authors. Published by the American Physical Society. We report the measurement of γγ→ηc(1S),ηc(2S)→η′π+π- with η′ decays to γρ and ηπ+π- using 941 fb-1 of data collected with the Belle detector at the KEKB asymmetric-energy e+e- collider. The ηc(1S) mass and width are measured to be M=[2984.6±0.7 (stat)±2.2 (syst)±0.3 (model)] MeV/c2 and Γ=[30.8-2.2+2.3 (stat)±2.5 (syst)±1.4 (model)] MeV, respectively. First observation of ηc(2S)→η′π+π- with a significance of 5.5σ including systematic error is obtained, and the ηc(2S) mass is measured to be M=[3635.1±3.7 (stat)±2.9 (syst)±0.4 (model)] MeV/c2. The products of the two-photon decay width and branching fraction (B) of decays to η′π+π- are determined to be ΓγγΓγγB=[65.4±2.6 (stat)±7.8 (syst)] eV for ηc(1S) and [5.6-1.1+1.2 (stat)±1.1 (syst)] eV for ηc(2S). The cross sections for γγ→η′π+π- and η′f2(1270) are measured for the first time.

    We study bottomonium production in association with an eta meson in e(+)e(-) annihilations near the gamma (5S), at a centre-of-mass energy of root 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 eta meson is reconstructed and the missing-mass spectrum of eta candidates is investigated. We observe the e(+)e(- )-> eta Upsilon(J)(1D) process and find evidence for the e(+)e(-) -> eta Upsilon(2S) process, while no significant signals of Upsilon(1S), h(b)(1P), nor h(b)(2P) are found. Cross sections for the studied processes are reported.

    We report the first observation of the hadronic transition
    $\Upsilon(4S)\to\eta'\Upsilon(1S)$, using 496 fb$^{-1}$ data collected at the
    $\Upsilon(4S)$ resonance with the Belle detector at the KEKB asymmetric-energy
    $e^{+}e^{-}$ collider. We reconstruct the $\eta'$ meson through its decays to
    $\rho^0\gamma$ and to $\pi^+\pi^-\eta$, with $\eta\to\gamma\gamma$. We measure:
    ${\cal B}(\Upsilon(4S)\to\eta'\Upsilon(1S))=(3.43\pm 0.88 {\rm(stat.)} \pm 0.21

    We search for CP violation in the charged charm meson decay D+ -> pi(+)pi(0), based on a data sample corresponding to an integrated luminosity of 921 fb(-1) collected by the Belle experiment at the KEKB e(+)e(-) asymmetric-energy collider. The measured CP-violating asymmetry is [+2.31 +/- 1.24(stat) +/- 0.23(syst)] %, which is consistent with the standard model prediction and has a significantly improved precision compared to previous results.

    We report evidence for the charged charmed-strange baryon Xi(c)(2930)(+) with a signal significance of 3.9 sigma with systematic errors included. The charged Xi(c)(2930)(+) is found in its decay to K-S(0)Lambda(+)(c) in the substructure of (B) over bar (0) -> K-S(0)Lambda(+)(c)(Lambda) over bar (-)(c) decays. The measured mass and width are [2942.3 +/- 4.4(stat.) +/- 1.5(syst.)] MeV/c(2) and [14.8 +/- 8.8(stat.) +/- 2.5(syst.)] MeV, respectively, and the product branching fraction is B((B) over bar (0) -> Xi(c)(2930)(+)(Lambda) over bar (-)(c)) B(Xi(c)(2930)(+) -> (K) over bar (0)(S)Lambda(+)(c)) = [2.37 +/- 0.51(stat.) +/- 0.31 (syst.)] x 10(-4). We also measure B((B) over bar (0) -> (K) over bar (0)(S)Lambda(+)(c)(Lambda) over bar (-)(c)) = [3.99 +/- 0.76(stat.) +/- 0.51(syst.)] x 10(-4) with greater precision than previous experiments, and present the results of a search for the charmonium-like state Y (4660) and its spin partner, Y-eta, in the Lambda(+)(c)(Lambda) over bar (-)(c) invariant mass spectrum. No clear signals of the Y (4660) or Y-eta are observed and the 90% credibility level (C.L.) upper limits on their production rates are determined. Thesemeasurements are obtained from a sample of (772 +/- 11) x 10(6) B (B) over bar pairs collected at the Upsilon(4S) resonance by the Belle detector at the KEKB asymmetric energy electron-positron collider.

    The Aerogel Ring Imaging Cherenkov (ARICH) counter is an upgrade of the forward endcap particle identification device in the upcoming Belle II experiment to secure 4σ separation of charged kaons and pions up to momenta of 3.5 GeV. Developments and productions of Silica aerogel radiator, Hybrid Avalanche Photo Detector (HAPD) and its readout electronics, key components of the ARICH counter, are done while surrounding subsystems; a power supply, a readout slow control and a LED light injection system are in operation. And then construction of the ARICH counter is ongoing in parallel to cosmic ray test. Details of the detector components with construction status are described and the test operation are discussed in the letter.

    We report the result of a search for the decay $B^{-}\to\mu^{-}\bar\nu_\mu$.
    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 ${\cal B}(B^{-}\to\mu^{-}\bar\nu_\mu)
    =(6.46 \pm 2.22 \pm 1.60 )\times10^{-7}$ or a frequentist 90% confidence level
    interval on the $B^{-}\to\mu^{-}\bar\nu_\mu$ branching fraction of $[2.9,
    10.7]\times 10^{-7}$. This result is obtained from a $711\ \text{fb}^{-1}$ data
    sample that contains $772 \times 10^6$ $B\bar{B}$ pairs, collected near the
    $\Upsilon(4S)$ resonance with the Belle detector at the KEKB asymmetric-energy

    The Aerogel Ring-Imaging Cherenkov detector (ARICH) is being installed in the endcap region of Belle II spectrometer to identify particles from B meson decays by detecting the Cherenkov ring image from aerogel radiators. To detect single photons, high-sensitive photon detector which has wide effective area (similar to 70 mm x 70 mm), a Hybrid Avalanche Photo Detector (HAPD), has been developed in a collaboration with Hamamatsu K.K. The HAPD consists of hybrid structure of a vacuum tube and an avalanche photodiode (APD). It can be operated in 1.5 T magnetic field of the spectrometer and withstands the radiation levels expected in the Belle II experiment. There are two steps of electric pulse amplification: acceleration of photo-electron in electric field in the vacuum tube part and electron avalanche in the APD part resulting in total gain of order 10(5). For the ARICH, we use 420 HAPDs in total. Before installing them, we performed quality assessment studies such as measurements of dark current, noise level, signal-to-noise ratio and two-dimensional scan with laser illumination. We also measured quantum efficiency of the photocathode. During the HAPD performance tests in the magnetic field, we observed very large signal pulses which cause long dead time of the readout electronics in some of the HAPDs. We have carried out a number of studies to understand this phenomenon, and have found a way to mitigate it and suppress the degradation of the ARICH performance. In this report, we will show a summary of the HAPD performance and quality assessment measurements including validation in the magnetic field for all of the HAPDs manufactured for the ARICH in the Belle II.

    PHYSICAL REVIEW D   97 ( 1 )   2017.9

     More details

    We present the measurement of the absolute branching fractions of $B^{+} \to
    X_{c\bar{c } } K^{+}$ and $B^{+} \to \bar{D}^{(\ast) 0} \pi^{+} $ decays, using a
    data sample of $772\times10^{6}$ $B\bar{B}$ pairs collected at the
    $\Upsilon(4S)$ resonance with the Belle detector at the KEKB asymmetric-energy
    $e^{+}e^{-}$ collider. Here, $X_{c\bar{c } }$ denotes $\eta_{c}$, $J/\psi$,
    $\chi_{c0}$, $\chi_{c1}$, $\eta_{c}(2S)$, $\psi(2S)$, $\psi(3770)$, $X(3872)$,
    and $X(3915)$. We do not observe significant signals for $X(3872)$ nor
    $X(3915)$, 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 present a search for a non-Standard-Model invisible particle X-0 in the mass range 0.1-1.8 GeV/c(2) in B+ -&gt; e(+)X(0) and B+ -&gt; mu X-+(0) decays. 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).

    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 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 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 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 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 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 report the first double differential cross sections of two charged pions and kaons (e(+)e(-) -&gt; 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 gamma (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(-) -&gt; 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 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.

    We report measurement of the cross section of e(+)e(-) -&gt; pi(+)pi(-)psi(2S) between 4.0 and 5.5 GeV, based on an analysis of initial state radiation events in a 980 fb(-1) data sample recorded with the Belle detector. The properties of the Y(4360) and Y(4660) states are determined. Fitting the mass spectrum of pi(+)pi(-)psi(2S) with two coherent Breit-Wigner functions, we find two solutions with identical mass and width but different couplings to electron-positron pairs: M-Y(4360) = (4347 +/- 6 +/- 3) MeV/c(2), Gamma(Y(4360)) = (103 +/- 9 +/- 5) MeV, M-Y(4660) = (4652 +/- 10 +/- 8) MeV/c(2), Gamma(Y(4660)) = (68 +/- 11 +/- 1) MeV; and B[Y(4360) -&gt; pi(+)pi(-)psi(2S)] . Gamma(e+e-)(Y(4360)) = (10.9 +/- 0.6 +/- 0.7) eV and B[Y(4660) -&gt; pi(+)pi(-)psi(2S)] . Gamma(e+e-)(Y(4660)) = (8.1 +/- 1.1 +/- 0.5) eV for one solution; or B[Y(4360) -&gt; pi(+)pi(-)psi(2S)] . Gamma(e+e-)(Y(4360)) = (9.2 +/- 0.6 +/- 0.6) eV and B[Y(4660) -&gt; pi(+)pi(-)psi(2S)] . Gamma(e+e-)(Y(4660)) = (2.0 +/- 0.3 +/- 0.2) eV for the other. Here, the first errors are statistical and the second systematic. Evidence for a charged charmoniumlike structure at 4.05 GeV/c(2) is observed in the pi(+/-)psi(2S) intermediate state in the Y(4360) decays.

    The dark photon A' and the dark Higgs boson h' are hypothetical constituents featured in a number of recently proposed dark sector models. Assuming prompt decays of both dark particles, we search for their production in the so-called Higgstrahlung channel e(+)e(-) -&gt; A'h', with h' -&gt; A'A'. We investigate ten exclusive final states with A' -&gt; e(+)e(-), mu(+)mu(-), or pi(+)pi(-) in the mass ranges 0.1 GeV/c(2) &lt; m(A') &lt; 3.5 GeV/c(2) and 0.2 GeV/c(2) &lt; m(h') &lt; 10.5 GeV/c(2). We also investigate three inclusive final states 2(e(+)e(-))X, 2(mu(+)mu(-))X, and (e(+)e(-))(mu(+)mu(-))X, where X denotes a dark photon candidate detected via missing mass, in the mass ranges 1.1 GeV/c(2) &lt; m(A') &lt; 3.5 GeV/c(2) and 2.2 GeV/c(2) &lt; m(h') &lt; 10.5 GeV/c(2). Using the entire 977 fb(-1) data set collected by Belle, we observe no significant signal. We obtain individual and combined 90% credibility level upper limits on the branching fraction times the Born cross section, B x sigma(Born), on the Born cross section sigma(Born), and on the dark photon coupling to the dark Higgs boson times the kinetic mixing between the standard model photon and the dark photon, alpha(D) x epsilon(2). These limits improve upon and cover wider mass ranges than previous experiments. The limits from the final states 3(pi(+)pi(-)) and 2(e(+)e(-))X are the first placed by any experiment. For alpha(D) equal to 1/137, m(h') &lt; 8 GeV/c(2), and m(A') &lt; 1 GeV/c(2), we exclude values of the mixing parameter epsilon above similar to 8 x 10(-4).

The inclusive branching fraction for M-Xs &lt; 2.8 GeV/c(2), which corresponds to a minimum photon energy of 1.9 GeV, is measured to be B(&lt;(B)over bar&gt; -&gt; X-s gamma) = (3.51 +/- 0.17 +/- 0.33) x 10(-4), where the first uncertainty is statistical and the second is systematic.

    We report a measurement of the B-0 and B+ meson decays to the (Ds-KS0)pi(+) and Ds-K+K+ final states, respectively, using 657 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. Using the D-s(-) -&gt; phi pi(-), K*(892)K-0(-) and (KSK-)-K-0 decay modes for the D-s reconstruction, we measure the following branching fractions: B(B-0 -&gt; (Ds-KS0)pi(+))= [0.47 +/- 0.06(stat) +/- 0.05(syst)] x 10(-4) and B(B+ -&gt; Ds-K+K+)= [0.93 +/- 0.22(stat) +/- 0.10(syst)] x 10(-5). We find the ratio of the branching fraction of B+ -&gt; Ds-K+K+ to that of the analogous Cabibbo-favored B+ -&gt; Ds-K+pi(+) decay to be R-B= 0.054 +/- 0.013(stat) +/- 0.006(syst), which is consistent with the naive factorization model.

    We search for the decay B-s(0) -&gt; gamma gamma and measure the branching fraction for B-s(0) -&gt; phi gamma 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. The B-s(0) -&gt; phi gamma branching fraction is measured to be (3.6 +/- 0.5(stat) +/- 0.3(syst) +/- 0.6(f(s))) x 10(-5), where f(s) is the fraction of B-s(()*())(B) over barB(s)(()*()) in b (b) over bar events. Our result is in good agreement with the theoretical predictions as well as with a recent measurement from LHCb. We observe no statistically significant signal for the decay B-s(0) -&gt; gamma gamma and set a 90% confidence- level upper limit on its branching fraction at 3.1 x 10(-6). This constitutes a significant improvement over the previous result.

    A proximity focusing RICH will be installed in the forward direction of the Belle II spectrometer, inside a super conducting solenoid coil with the magnetic field of 1.5 T. Photons emitted in the sequence of two different aerogel radiator layers will be registered by the Hybrid Avalanche Photo Diodes. By detecting more than 11 photons per incident 4 GeV/c pion, with 15 mrad single photon Cherenkov angle resolution, the designed detector should enable an efficient separation of kaons from pions in the wide range of particle momenta from 0.5 GeV/c up to 4 GeV/c,
    The particle separation will be based on a two-dimensional extended maximum likelihood analysis. The position dependence of the efficiencies for identification of pions and kaons shows a very homogeneous response over the detector area. The performance on the edge of the detector is improved by employing planar mirrors to reflect the Cherenkov photons on the detector plane. The results show that by using a designed detector configuration the kaon pion separation efficiency of more than 95% can be achieved at a very low pion misidentification probability of 1%. In the low momentum region (0.5 GeV/c-0.8 GeV/c) the variation of detected number of photons due to matching of aerogel refractive index and the gaps between the sensitive areas on the detector plane results in a slightly decreased separation efficiency.

    This paper presents recent progress in the development and mass production of large-area hydrophobic silica aerogels for use as radiators in the aerogel-based ring-imaging Cherenkov (A-RICH) counter, which will be installed in the forward end cap of the Belle II detector. The proximity-focusing A-RICH system is especially designed to identify charged kaons and pions. The refractive index of the installed aerogel Cherenkov radiators is approximately 1.05, and we aim for a separation capability exceeding 4a at momenta up to 4 GeV/c. Large-area aerogel Liles (over 18 x 18 x 2 cm(3)) were first fabricated in Lest productions by pin drying in addition to conventional methods. We proposed to fill the large end-cap region (area 3.5 m2) with 124 water-jet-trimmed fan-shaped dual-layer-focusing aerogel combinations of different refractive indices (1.045 and 1.055). Guided by the test production results, we decided to manufacture aerogels by the conventional method and are currently proceeding with mass production. In an electron beam Lest undertaken at the DESY, we confirmed that the Klif separation capability of a prototype A-RICH counter exceeded 4c at 4 GeWc. (C) 2014 Elsevier By. All rights reserved.

    We report development and current status of Aerogel Ring Imaging Cherenkov counter (ARICH) which is a particle identification detector in the next generation B-factory experiment, the Belle II. The main components of the ARICH are aerogel radiator and photon sensor. When a charged particle goes through the radiator, it emits Cherenkov light photons to the direction which depends on the particle velocity. Combining observables in the Belle II detector, such as a momentum measured with tracker installed inside of the ARICH, and directions of the Cherenkov light photons with the ARICH, we obtain the charged particle mass information. A new photon sensor named Hybrid Avalanche Photon Detector (HAPD) is used to collect a small number of the Cherenkov light photons distributed in the large area effectively. We set up a small part of the ARICH detector and perform the measurement using electron and hadron beam lines at KEK, CERN and DESY. From the obtained results, we expect that it is possible to separate K- and pi-mesons by more than 5 sigma significance level with the ARICH design. The HAPD and its readout electronics production has been started and several kinds of the quality testing for them are ongoing. We also simulate the whole ARICH detector with a GEANT4-based program and expected performance of the particle identification is sufficient for charged tracks in a wide momentum range. After finishing the production of the all components, the construction of the ARICH detector will start in this year and installation to the Belle II detector will be completed in 2015.

    We report a high-statistics measurement of the differential cross section of the process gamma gamma -&gt; (KSKS0)-K-0 in the range 1.05 GeV &lt;= W &lt;= 4.00 GeV, where W is the center-of-mass energy of the colliding photons, using 972 fb(-1) of data collected with the Belle detector at the KEKB asymmetric-energy e(+)e(-) collider operated at and near the Upsilon-resonance region. The differential cross section is fitted by parameterized S-, D-0-, D-2-, G(0)-, and G(2)-wave amplitudes. In the D-2 wave, the f(2)(1270), a(2)(1320), and f(2)'(1525) are dominant and a resonance, the f(2)(2200), is also present. The f(0)(1710) and possibly the f(0)(2500) are seen in the S wave. The mass, total width, and product of the two-photon partial decay width and decay branching fraction to the K (K) over bar state Gamma(gamma gamma) B(K (K) over bar) are extracted for the f(2)'(1525), f(0)(1710), f(2)(2200), and f(0)(2500). The destructive interference between the f(2)(1270) and a(2)(1320) is confirmed by measuring their relative phase. The parameters of the charmonium states chi(c0) and chi(c2) are updated. Possible contributions from the chi(c0)(2P) and chi(c2)(2P) states are discussed. A new upper limit for the branching fraction of the P- and CP-violating decay channel eta(c) -&gt; (KSKS0)-K-0 is reported. The detailed behavior of the cross section is updated and compared with QCD-based calculations.

    We present a measurement of the charge-parity (CP) violating parameters in B-0 -&gt; pi(+) pi(-) decays. The results are obtained from the final data sample containing 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 obtain the CP violation parameters
    A(cp)(B-0 -&gt; pi(+) pi(-)) = +0.33 +/- 0.06(stat) +/- 0.03(syst),
    S-cp(B-0 -&gt; pi(+) pi(-)) = -0.64 +/- 0.08(stat) +/- 0.03(syst),
    where A(CP) and S-CP represent the direct and mixing-induced CP asymmetries in B-0 -&gt; pi(+) pi(-) decays, respectively. Using an isospin analysis including results from other Belle measurements, we find 23.8 degrees &lt; phi(2) &lt; 66.8 degrees is disfavored at the 1 sigma level, where phi(2) is one of the three interior angles of the Cabibbo-Kobayashi-Maskawa unitarity triangle related to B-u,B-d decays.

    We search for bottomonium states in Υ(2S)→(bb̄)γ decays with an integrated luminosity of 24.7 fb-1 recorded at the Υ(2S) resonance with the Belle detector at KEK, containing (157.8±3.6)×106 Υ(2S) events. The (bb̄) system is reconstructed in 26 exclusive hadronic final states composed of charged pions, kaons, protons, and KS0 mesons. We find no evidence for the state recently observed around 9975 MeV (Xbb̄) in an analysis based on a data sample of 9.3×106 Υ(2S) events collected with the CLEO III detector. We set a 90% confidence level upper limit on the branching fraction B[Υ(2S)→Xbb̄γ]×ΣiB[X bb̄→hi]<4.9×10-6, summed over the exclusive hadronic final states employed in our analysis. This result is an order of magnitude smaller than the measurement reported with CLEO data. We also set an upper limit for the ηb(1S) state of B[Υ(2S)→ηb(1S)γ]×ΣiB[η b(1S)→hi]<3.7×10-6. © 2013 American Physical Society.

    We report the first observation of Upsilon(10860) -&gt; Upsilon(1, 2, 3S)pi(0)pi(0) decays. The neutral partner of the Z(1/b)(10610), the Z(b)(0)(10610) decaying to Upsilon(2, 3S)pi(0), is observed for the first time with a 6.5 sigma significance using a Dalitz analysis of Upsilon(10860) -&gt; Upsilon (2, 3S)pi(0)pi(0) decays. The results are obtained with a 121.4 fb(-1) data sample collected with the Belle detector at the Upsilon(10860) resonance at the KEKB asymmetric- energy e(+)e(-) collider.

    The cross section for e(+)e(-) -&gt; pi(+)pi(-) J/psi between 3.8 and 5.5 GeV is measured with a 967 fb(-1) data sample collected by the Belle detector at or near the Upsilon(nS) (n = 1, 2, . . . , 5) resonances. The Y(4260) state is observed, and its resonance parameters are determined. In addition, an excess of pi(+)pi(-) J/psi production around 4 GeV is observed. This feature can be described by a Breit-Wigner parametrization with properties that are consistent with the Y(4008) state that was previously reported by Belle. In a study of Y(4260) -&gt; pi(+)pi(-) J/psi decays, a structure is observed in the M(pi(+/-) J/psi) mass spectrum with 5.2 sigma significance, with mass M = (3894.5 +/- 6.6 +/- 4.5) MeV/c(2) and width Gamma = (63 +/- 24 +/- 26) MeV/c(2), where the errors are statistical and systematic, respectively. This structure can be interpreted as a new charged charmoniumlike state.

    We report a search for charmless hadronic decays of neutral B mesons to the final state K+K-pi(0). The results are based on a 711 fb(-1) data sample that contains 772 x 10(6) B (B) over bar pairs, and was collected at the (sic)(4S) resonance with the Belle detector at the KEKB asymmetric-energy e(+)e(-) collider. We find the first evidence for this decay with a significance of 3.5 standard deviations and measure its branching fraction as B(B-0 -&gt; K+K-pi(0)) = [2.17 +/- 0.60(stat) +/- 0.24(syst) x 10(-6).

    This paper describes recent progress in the development of large-area hydrophobic silica aerogel tiles for use as a radiator in the aerogel-based ring-imaging Cherenkov (A-RICH) counter that will be installed in the forward end cap of the Belle II detector. The proximity-focusing A-RICH counter is designed to efficiently identify charged pions and kaons; our goal is a separation capability of more than 4 sigma at momenta up to 4 GeV/c. We plan to fill the large end-cap area of 3.5 m(2) with 124 segmented dual-layer-focusing aerogel combinations with different refractive indices (n similar to 1.05). It is crucial to minimize the number of aerogel tiles to reduce tile boundaries because the number of detected photoelectrons decreases at the boundaries. As a step toward achieving high performance in the actual detector, we performed test productions of large-area (over 18 x 18 x 2 cm(3)) aerogel tiles using both conventional and pin-drying methods. In view of the crack-free production yield, we have decided to mass-produce both upstream and downstream aerogel tiles by the conventional method in the Belle II program, although the pin-dried aerogels showed excellent transparency. We also used an electron beam at DESY to conduct a beam test for investigating the performance of a prototype A-RICH counter. When we used a basic counter configuration with dual-layer-focusing aerogels having n similar to 1.045 and 1.055 produced by the conventional method, we confirmed a pi/K separation capability better than 4 sigma at a momentum of 4 GeV/c.

    The processes gamma gamma -&gt; omega phi,phi phi, and omega omega are measured using an 870 fb(-1) data sample collected with the Belle detector at the KEKB asymmetric-energy e(+)e(-) collider. Production of vector meson pairs is clearly observed and their cross sections are measured for masses that range from threshold to 4.0 GeV. In addition to signals from well established spin-zero and spin-two charmonium states, there are resonant structures below charmonium threshold, which have not been previously observed. We report a spin-parity analysis for the new structures and determine the products of the eta(c), chi(c0), and chi(c2) two-photon decay widths and branching fractions to omega phi,phi phi, and omega omega.

The results for the branching fractions are: B(B-0 -&gt; J/psi eta) = (12.3 +/-(1.8)(1.7)+/- 0.7) x 10(-6) and B(B-0 -&gt; J/psi eta') &lt; 7.4 x 10(-6) at 90% confidence level. The eta-eta' mixing angle is constrained to be less than 42.2 degrees at 90% confidence level.

    We present a precise measurement of the CP violation parameter sin2 phi(1) and the direct CP violation parameter A(f) using the final data sample of 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. One neutral B meson is reconstructed in a J / psi K-S(0), psi (2S)K-S(0), chi K-c1(S)0, or J / psi K-L(0) CP eigenstate and its flavor is identified from the decay products of the accompanying B meson. From the distribution of proper-time intervals between the two B decays, we obtain the following CP violation parameters: sin2 phi(1) = 0.667 +/- 0.023(stat) +/- 0.012(syst) and A(f) = 0.006 +/- 0.016(stat) +/- 0.012(syst).

    Using a sample of 158 x 10(6) Y(2S) events collected with the Belle detector, we search for the first time for double-charmonium decays of the P-wave spin-triplet bottomonium states (Y(2S) -&gt; gamma chi(bJ), chi(bJ) -&gt; J/psi J/psi, J/psi psi', psi'psi' for J 0, 1, and 2). No significant chi(bJ) signal is observed in the double-charmonium mass spectra, and we obtain the following upper limits: B(chi(bJ) -&gt; J/psi J/psi) &lt; 7.1 x 10(-5), 2.7 x 10(-5), 4.5 x 10(-5), B(chi(bJ) -&gt; J/psi psi') &lt; 1.2 x 10(-4), 1. 7 x 10(-5), 4.9 x 10(-5), B(chi(bJ) -&gt; psi'psi') &lt; 3.1 x 10(-5), 6.2 x 10(-5), 1.6 x 10(-5) for J = 0, 1, and 2, respectively, at the 90% confidence level. These limits are significantly lower than the central values (with uncertainties of 50% to 70%) predicted using the light cone formalism but are consistent with calculations using the nonrelativistic QCD (NRQCD) factorization approach.

    We report a new sensitive search for C P T violation, which includes improved measurements of the C P T-violating parameter z and the total decay-width difference normalized to the averaged width delta(d) delta(d) of the two B-d mass eigenstates . The results are based on a data sample of 535 x 10(6) B B pairs collected at the Epsilon(4 S) resonance with the Belle detector at the KEKB asymmetric-energy e(+) e(-) collider. We obtain Re (z) = [+1.9 +/- 3.7 (stat) +/- 3.3 (syst)] x 10(&gt;-2), qm (z) = [-5.7 +/- 3.3 (stat) +/- 3.3 (syst)] x 10(-3), and delta(d) / delta(d) = [-1.7 +/- 1.8 (stat) +/- 1.1 (syst)] x 10(-2), all of which are consistent with zero. This is the most precise single measurement of these parameters in the neutral B-meson system to date.

    We report a measurement of the CP-violation parameter sin2 phi(1) at the Y(5S) resonance using a new tagging method, called "B-pi tagging.'' In Y(5S) decays containing a neutral B meson, a charged B, and a charged pion, the neutral B is reconstructed in the J / psi K-S(0) CP-eigenstate decay channel. The initial flavor of the neutral B meson at the moment of the Y(5S) decay is opposite to that of the charged B and may thus be inferred from the charge of the pion without reconstructing the charged B. From the asymmetry between B-pi(+) and B-pi(-) tagged J / psi K-S(0) yields, we determine sin2 phi(1) 0.57 +/- 0.58(stat) +/- 0.06(syst). The results are based on 121 fb(-1) of data recorded by the Belle detector at the KEKB e(+)e(-) collider.

The measured branching fractions are B(B-+/- -&gt; eta K-+/-) = (2.12 +/- 0.23 +/- 0.11) x 10(-6), B(B-+/- -&gt; eta pi(+/-)) = (4.07 +/- 0.26 +/- 0.21) x 10(-6), and B(B-0 -&gt; eta K-0) = (1.27(-0.29)(+0.33) +/- 0.08) x 10(-6), where the last decay is observed for the first time with a significance of 5.4 standard deviations (sigma). We also find evidence for CP violation in the charged B modes, A(CP)(B-+/- -&gt; eta K-+/-) = -0.38 +/- 0.11 +/- 0.01 and A(CP)(B-+/- -&gt; eta pi(+/-)) = -0.19 +/- 0.06 +/- 0.01 with significances of 3.8 sigma and 3.0 sigma, respectively. For all measurements, the first and second uncertainties are statistical and systematic, respectively.

    We report the first observation of the radiative decay B-0 -&gt; phi K-0 gamma using a data sample of 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 observe a signal of 37 +/- 8 events with a significance of 5.4 standard deviations including systematic uncertainties. The measured branching fraction is B(B-0 -&gt;phi K-0 gamma) = (2.74 +/- 0.60 +/- 0.32) x 10(-6), where the uncertainties are statistical and systematic, respectively. We also report the first measurements of time-dependent CP-violation parameters: S-phi K0s gamma = +0.74(-1.05)(+0.72)(stat)(-0.024)(+0.10)(syst) and A phi(0)(Ks)gamma = +0.35 +/- 0.58(stat)(-0.10)(+0.23)(syst). Furthermore, we measure B(B+ -&gt; phi K+gamma) = (2.48 +/- 0.30 +/- 0.24) x 10(-6), A(CP) = -0.03 +/- 0.11 +/- 0.08, and find that the signal is concentrated in the M-phi K mass region near threshold.

    We report the observation of two narrow structures at 10610 MeV/c 2 and 10650 MeV/c2 in the π ±γ(nS) (n = 1,2,3) and π±hb(mP) (m = 1,2) mass spectra that are produced in association with a single charged pion in γ(5S) decays. The measured masses and widths of the two structures averaged over the five final states are M1 = 10608.4 ± 2.0MeV/c2, γ1 = 15.6 ± 2.5 MeV and M 2 = 10653.2 ± 1.5 MeV/c2, γ2 = 14.4 ±3.2 MeV. Analysis favors quantum numbers of IG(J P)=1+(1+) for both states. The results are obtained with a 121.4 fb-1 data sample collected with the Belle detector near the γ(5S) resonance at the KEKB asymmetric-energy e+e- collider.

    We report a measurement of CP violating asymmetries in B-0 ((B-0) over bar) -&gt; (K+K-KS0) decays with a time-dependent Dalitz approach. This analysis is based on a data sample of 657 x 10(6) B (B) over bar pairs accumulated at the Y(4S) resonance with the Belle detector at the KEKB asymmetric-energy e(+) e(-) collider. As the result of an unbinned maximum likelihood fit to the selected candidates, the mixing-induced and direct CP violation parameters phi(eff)(1) and A(CP) are obtained for B-0 -&gt; phi(1020)K-S(0), B-0 -&gt; f(0)(980)K-S(0), and other B-0 -&gt; (K+K-KS0) decays. We find four solutions that describe the data. There are phi(eff)(1) (B-0 -&gt; phi(1020)K-S(0)) = (32.2 +/- 9.0 +/- 2.6 +/- 1.4); phi(eff)(1)(B-0 -&gt; phi(1020)K-S(0)) = 26.2 +/- 8.8 +/- 2.7 +/- 1.2); phi(eff)(1)(B-0 phi(1020)K-S(0)) = (27.3 +/- 8.6 +/- 2.8 +/- 1.3); and phi(eff)(1)(B-0 -&gt; phi(1020)K-S(0)) = (24.3 +/- 8.0 +/- 2.9 +/- 5.2). The values for the CP violating phase in B-0 -&gt; phi(1020)K-S(0) are similar, but other properties of the Dalitz plot are quite different for the four solutions. These four solutions have consistent phi(eff)(1) values for all three B-meson decay channels and none of them deviates significantly from the values measured in B -&gt; (c (c) over bar )K-0 decays with the currently available statistics. In addition, we find no significant direct CP violation.

    We report measurements of CP violation parameters in B-0 -&gt; K-0 pi(0) decays based on a data sample of 657 X 10(6)B (B) over bar pairs collected with the Belle detector at the KEKB e(+)e(-) asymmetric-energy collider. We use B-0 -&gt; K-S(0)pi(0) decays for both mixing-induced and direct CP violating asymmetry measurements and B-0 -&gt; K-L(0)pi(0) decays for the direct CP violation measurement. The CP violation parameters obtained are sin2 phi(eff)(1) - +0.67 +/- 0.31(stat) +/- 0.08(syst) and A(K0 pi 0) - +0.14 +/- 0.13(stat) +/- 0.06(syst). The branching fraction of B-0 -&gt; K-0 pi(0) decay is measured to be B(B-0 -&gt; K-0 pi(0)) - (8.7 +/- 0.5(stat) +/- 0.6(syst)) X 10(-6). The observed A(K0 pi 0) value differs by 1.9 standard deviations from the value expected from an isospin sum rule.

    We report measurements of CP violation parameters in B0→K0π0 decays based on a data sample of 657×106BB̄ pairs collected with the Belle detector at the KEKB e+e- asymmetric-energy collider. We use B0→KS0π0 decays for both mixing-induced and direct CP violating asymmetry measurements and B0→KL0π0 decays for the direct CP violation measurement. The CP violation parameters obtained are sin 2 1eff=+0.67±0. 31(stat)±0.08(syst) and AK0π0=+0.14±0.13(stat)±0. 06(syst). The branching fraction of B0→K0π0 decay is measured to be B(B0→K0π0)=(8.7±0.5(stat.)±0.6(syst.))×10 -6. The observed AK0π0 value differs by 1.9 standard deviations from the value expected from an isospin sum rule. © 2010 The American Physical Society.

    We present a high-statistics measurement of differential cross sections and the total cross section for the process gamma gamma -&gt; pi(0)pi(0) in the kinematic range 0.6 GeV &lt;= W &lt;= 4.0 GeV and vertical bar cos theta*vertical bar &lt;= 0.8, where W and theta* are the energy and pion scattering angle, respectively, in the gamma gamma center-of-mass system. Differential cross sections are fitted to obtain information on S, D(0), D(2), G(0), and G(2) waves. The G waves are important above W similar or equal to 1.6 GeV. The general behavior of partial waves is studied by fitting differential cross sections in a simple parametrization where amplitudes contain resonant contributions and smooth background. The D(2) wave is dominated by the f(2)(1270) meson whose parameters are consistent with the current world averages. The D(0) wave contains a f(2)(1270) component, whose fraction is fitted. For the S wave, the f(0)(980) parameters are found to be consistent with the values determined from our recent pi(+) pi(-) data. In addition to the f(0)(980), the S wave prefers to have another resonance-like contribution whose parameters are obtained.

    We report improved measurements of time-dependent CP violation parameters for B-0((B) over bar (0))-&gt; J/psi pi(0) decay. This analysis is based on 535x10(6) B (B) over bar pairs accumulated at the Upsilon(4S) resonance with the Belle detector at the KEKB asymmetric-energy e(+)e(-) collider. From the distribution of proper time intervals between the two B decays, we obtain the following CP violation parameters S-J/psi pi(0)=-0.65 +/- 0.21(stat)+/- 0.05(syst) and A(J/psi pi)(0)=+0.08 +/- 0.16(stat)+/- 0.05(syst),which are consistent with standard model expectations.

Attributing the signals to the Upsilon(5S) resonance, the partial widths Gamma(Y(5S) -&gt; Y(1S)pi(+)pi(-)) = 0.59 +/- 0.04(stat)+/- 0.09(syst) MeV and Gamma(Y(5S) -&gt; Y(2S)pi(+)pi(-)) = 0.85 +/- 0.07(stat)+/- 0.16(syst) MeV are obtained from the observed cross sections. These values exceed by more than 2 orders of magnitude the previously measured partial widths for dipion transitions between lower Y resonances.

    Equal amounts of matter and antimatter are predicted to have been produced in the Big Bang, but our observable Universe is clearly matter- dominated. One of the prerequisites(1) for understanding this elimination of antimatter is the nonconservation of charge- parity ( CP) symmetry. So far, two types of CP violation have been observed in the neutral K meson ( K-0) and B meson ( B-0) systems: CP violation involving the mixing(2) between K-0 and its antiparticle (K) over bar (0) ( and likewise(3,4) for B-0 and (B) over bar (0)), and direct CP violation in the decay of each meson(5-8). The observed effects for both types of CP violation are substantially larger for the B-0 meson system. However, they are still consistent with the standard model of particle physics, which has a unique source(9) of CP violation that is known to be too small(10) to account for the matter-dominated Universe. Here we report that the direct CP violation in charged B-+/- --&gt; K-+/- pi(0) decay is different from that in the neutral B-0 counterpart. The direct CP- violating decay rate asymmetry, A(K)+/- (pi 0) ( that is, the difference between the number of observed B- --&gt; K- pi(0) event versus B+ --&gt; K+ pi(0) events, normalized to the sum of these events) is measured to be about +7%, with an uncertainty that is reduced by a factor of 1.7 from a previous measurement(7). However, the asymmetry A(K+/-) p(-/+) for B-0 --&gt; K- pi(+) versus B-0 --&gt; K+ pi(-) is at the -10% level(7,8). Although it is susceptible to strong interaction effects that need further clarification, this large deviation in direct CP violation between charged and neutral B meson decays could be an indication of new sources of CP violation - which would help to explain the dominance of matter in the Universe.

    We report the observation of a new D-sJ meson produced in B+-&gt;(D) over bar D-0(sJ)-&gt;(D) over bar (DK+)-D-0-K-0. This state has a mass of M=2708 +/- 9(-10)(+11) MeV/c(2), a width Gamma=108 +/- 23(-31)(+36) MeV/c(2) and a 1(-) spin-parity. The statistical significance of this observation is 8.4 sigma. The results are based on an analysis of 449x10(6) B (B) over bar events collected at the Gamma(4S) resonance with the Belle detector at the KEKB asymmetric-energy e(+)e(-) collider.

    We report a measurement of the CP-violating parameters in B(0)-&gt; K(S)(0)K(S)(0) decays based on a data sample of 657x10(6) B (B) over bar pairs collected at the Upsilon(4S) resonance with the Belle detector at the KEKB asymmetric-energy e(+)e(-) collider. In this Letter, one neutral B meson is fully reconstructed in the B(0)-&gt; K(S)(0)K(S)(0) decay mode, and the flavor of the accompanying B meson is identified by its decay products. The CP-violating parameters are measured from the asymmetry in the distributions of the proper-time interval between the two B decays: S(KS)(0)K(S)(0)=-0.38(-0.77)(+0.69)(stat)+/- 0.09(syst) and A(KS)(0)K(S)(0)=-0.38 +/- 0.38(stat)+/- 0.05(syst).

    We present measurements of time-dependent CP asymmetries in B0→ωKS0, f0(980)KS0, KS0π0 and K+K-KS0 decays based on a sample of 535×106 BB̄ pairs collected at the Υ(4S) resonance with the Belle detector at the KEKB energy-asymmetric e+e- collider. One neutral B meson is fully reconstructed in one of the specified decay channels, and the flavor of the accompanying B meson is identified from its decay products. CP-violation parameters for each of the decay modes are obtained from the asymmetries in the distributions of the proper-time intervals between the two B decays. © 2007 The American Physical Society.

    We present measurements of time-dependent CP asymmetries in B-0 -&gt;omega K-S(0), f(0)(980)K-S(0), K-S(0)pi(0) and (K+K-KS0) decays based on a sample of 535x10(6) B (B) over bar pairs collected at the Upsilon(4S) resonance with the Belle detector at the KEKB energy-asymmetric e(+)e(-) collider. One neutral B meson is fully reconstructed in one of the specified decay channels, and the flavor of the accompanying B meson is identified from its decay products. CP-violation parameters for each of the decay modes are obtained from the asymmetries in the distributions of the proper-time intervals between the two B decays.

    We report the first search for CP-violating decays of the Y(4S) using a data sample that contains 535 x 10(6) Y(4S) mesons with the Belle detector at the KEKB asymmetric-energy e(+) e(-) collider. A partial reconstruction technique is employed to enhance the signal sensitivity. No significant signals were observed. We obtain an upper limit of 4 x 10(-7) at the 90% confidence level for the branching fractions of the CP violating modes, Y(4S) -&gt; B-0(B) over bar (0) -&gt; J/psi K-S(0) + J/psi(eta K-c)(S)0. Extrapolating the result, we find that an observation with 5 sigma significance is expected with a 30 ab(-1) data sample, which is within the reach of a future super B factory.

    We report measurements of branching fractions for B -&gt; K pi and B -&gt;pi pi decays based on a data sample of 449x10(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 also measure the ratios of partial widths for B -&gt; K pi decays, namely R-c equivalent to 2 Gamma(B+-&gt; K+pi(0))/Gamma(B+-&gt; K-0 pi(+))=1.08 +/- 0.06 +/- 0.08 and R-n equivalent to Gamma(B-0 -&gt; K+pi(-))/2 Gamma(B-0 -&gt; K-0 pi(0))=1.08 +/- 0.08 +/- 0.08, where the first and the second errors are statistical and systematic, respectively. These ratios are sensitive to enhanced electroweak penguin contributions from new physics; the new measurements are, however, consistent with standard model expectations.

    We reconstruct (B) over bar (0)-&gt; Ds-D+ decays using a sample of 449x10(6) B (B) over bar pairs recorded by the Belle experiment, and measure the branching fraction to be B((B) over bar (0)-&gt; Ds-D+)=[7.5 +/- 0.2(stat)+/- 0.8(syst)+/- 0.8(B(')s)]x10(-3). A search for the related decay (B) over bar (0)-&gt; Ds+Ds- is also performed. Since we observe no statistically significant signal, an upper limit on the branching fraction is set at 3.6x10(-5) (90% C.L.).

    We report a measurement of the inclusive electron energy spectrum for charmed semileptonic decays of B mesons in a 140 fb(-1) data sample collected at the Y(4S) resonance with the Belle detector at the KEKB asymmetric energy e(+) e(-) collider. We determine the first four moments of the electron energy spectrum for threshold values of the electron energy between 0.4 and 2.0 GeV. In addition, we provide values of the partial branching fraction (zeroth moment) for the same electron threshold energies, and independent measurements of the B+ and B-0 partial branching fractions at 0.4 GeV and 0.6 GeV electron threshold energies. We measure the independent B+ and B-0 partial branching fractions with electron threshold energies of 0.4 GeV to be Delta B(B+ -&gt; X(c)ev) = (10.79 +/- 0.25 (stat.) +/- 0.27 (sys.))% and Delta B(B-0 -&gt; X(c)ev) = (10.08 +/- 0.30 (stat.) +/- 0.22 (sys.))%. Full correlations between all measurements are evaluated.

    The inclusive production of D-s, D-0, and J/psi mesons is studied using a 1.86 fb(-1) data sample collected on the Y(5S) resonance with the Belle detector at the KEKB asymmetric-energy e(+)e(-) collider. The number of bb events in this Y(5S) data sample is determined. We measure the branching fractions B(Y(5S) -&gt; DsX)/2 = (23.6 +/- 1.2 +/- 3.6)%, B(Y(5S) -&gt; (DX)-X-0)/2 = (53.8 +/- 2.0 +/- 3.4)%, and B(Y(5S) -&gt; J/psi X)/2 = (1.030 +/- 0.080 +/- 0.067)%. From the D-s and D-0 inclusive branching fractions the ratio f(s) = (18.0 +/- 1.3 +/- 3.2)% of B-s((*)) B-s((*)) to the total bb quark pair production at the Y(5S) energy is obtained in a model-dependent way.

    We present improved measurements of CP-violation parameters in B-0 -&gt; phi K-0, eta K-'(0), (KSKSKS0)-K-0-K-0 decays based on a sample of 535 x 10(6) B (B) over bar pairs collected at the Upsilon(4S) resonance with the Belle detector at the KEKB energy-asymmetric e(+)e(-) collider. We obtain sin2 phi(eff)(1) = +0.64 +/- 0.10(stat) +/- 0.04(syst) for B-0 -&gt; eta K-'(0), +0.50 +/- 0.21(stat) +/- 0.06(syst) for B-0 -&gt;phi K-0, and +0.30 +/- 0.32(stat) +/- 0.08(syst) for B-0 -&gt; (KSKSKS0)-K-0-K-0 decays. We have observed CP violation in the B-0 -&gt; eta K-'(0) decay with a significance of 5.6 standard deviations. We also perform an improved measurement of CP asymmetries in B-0 -&gt; J/psi K-0 decays and obtain sin2 phi(1) = +0.642 +/- 0.031(stat) +/- 0.017(syst).

    We have measured branching fractions of hadronic τdecays involving an η meson using 485 fb-1 of data collected with the Belle detector at the KEKB asymmetric-energy e+e- collider. We obtain the following branching fractions: B(τ - → K-ην) = (1.62 ± 0.05 ± 0.09) × 10-4, B(τ - → K-η0π=ηντ ) = (4.7 ± 1.1 ± 0.4) × 10-5, B(τ - → π-π0ηντ ) = (1.39 ± 0.03 ± 0.07) × 10-3, and B(τ - → K-ην7tau
    ) = (1.13 ±0.19 ± 0.07) ×10-4 improving the accuracy compared to the best previous measurements by factors of six, eight, four and four, respectively.

    We have searched for neutrinoless τ lepton decays into ℓ and V 0, where ℓ stands for an electron or muon, and V 0 for a vector meson (φ, ω, K*0 or ̄K* 0), using 543 fb-1 of data collected with the Belle detector at the KEKB asymmetric-energy e+e- collider. No excess of signal events over the expected background is observed, and we set upper limits on the branching fractions in the range (0.7- 1.8) ×10-7 at the 90% confidence level. These upper limits include the first results for ℓω as well as new limits that are 3.6 - 9.6 times more restrictive than our previous results for ℓφ, ℓKπ and ℓ ̄K *0.

    We search for the doubly charmed baryonic decay B̄0 → Λ + cΛ ̄̄cin a data sample of 520 × 106 B ̄B events accumulated at the γ(4S) resonance with the Belle detector at the KEKB asymmetricenergy e+e- collider. We find no significant signal and set an upper limit of B B̄0 → Λ + cΛ ̄̄c) 6.2 × 10-5 at 90% confidence level. The result is significantly below a naive extrapolation fromB(B̄→ Ε0c̄ Λc ) assuming a simple Cabibbo-suppression factor of |Vcd/Vcs|2. The small branching fraction could be attributed to a suppression due to the large momentum of the baryonic decay products, which has been observed in other charmed baryonic two-body B decays.

    We present the first evidence of the decay B--&gt;tau(-)nu(tau), using 414 fb(-1) of data collected at the Upsilon(4S) resonance with the Belle detector at the KEKB asymmetric-energy e(+)e(-) collider. Events are tagged by fully reconstructing one of the B mesons in hadronic modes. We detect the signal with a significance of 3.5 standard deviations including systematics and measure the branching fraction to be B(B--&gt;tau(-)nu(tau))=(1.79(-0.49)(+0.56)(stat)(-0.51)(+0.46)(syst))x10(-4). This implies that f(B)=0.229(-0.031)(+0.036)(stat)(-0.037)(+0.034)(syst) GeV and is the first direct measurement of this quantity.

    We have searched for neutrinoless tau lepton decays into lhh or lV(0), where l stands for an electron or muon, h for a charged light hadron, pi or K, and V-0 for a neutral vector meson, rho(0), K*(892)(0) and phi, using a 158 fb(-1) data sample collected with the Belle detector at the KEKB e(+)e(-) collider. Since the number of events observed are consistent with the expected background, we set upper limits on the branching fractions in the range of (1.6-8.0) x 10(-7) for various decay modes at the 90% confidence level.

The results are obtained from a data sample of 386x10(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 measure B(B+-&gt;eta(')pi(+))=[1.76(-0.62)(+0.67)(stat)(-0.14)(+0.15)(syst)]x10(-6) and B(B-0 -&gt;eta(')pi(0))= [2.79(-0.96)(+1.02)(stat)(-0.34)(+0.25)(syst)]x10(-6).

    The Collins effect connects transverse quark spin with a measurable azimuthal dependence in the yield of hadronic fragments around the quark's momentum vector. Using two different reconstruction methods, we find evidence of statistically significant azimuthal asymmetries for charged pion pairs in e(+)e(-) annihilation at a center-of-mass energy of 10.52 GeV, which can be attributed to a transverse polarization of the primordial quarks. The measurement was performed using a sample of 79x10(6) hadronic events collected with the Belle detector.

    We present an analysis of charm quark fragmentation at 10.6 GeV, based on a data sample of 103 fb(-1) collected by the Belle detector at the KEKB accelerator. We consider fragmentation into the main charmed hadron ground states, namely D-0,D+,D-s(+) and Lambda(c)(+), as well as the excited states D-*0 and D*+. The fragmentation functions are important to measure as they describe processes at a low energy scale, where calculations in perturbation theory lead to large uncertainties. Fragmentation functions can also be used as input distributions for Monte Carlo generators. Additionally, we determine the average number of these charmed hadrons produced per B decay at the Upsilon(4S) resonance and measure the distribution of their production angle in e(+)e(-) annihilation events and in B decays.

    We present spectra of prompt electrons from decays of neutral and charged B mesons. The results are based on 140 fb(-1) of data collected by the Belle detector on the Y(4S) resonance at the KEKB e(+)e(-) asymmetric collider. We tag Y(4S) BB events by reconstructing a B meson in one of several hadronic decay modes; the semileptonic decay of the other B meson is inferred from the presence of an identified electron. We obtain for charged and neutral B mesons the partial rates of semileptonic decay, to electrons with momentum greater than 0.6 GeV/c in the B rest frame, and their ratio b(+)/b(0) = 1.08 +/- 0.05 +/- 0.02, where the first and second errors are statistical and systematic, respectively.

The results are obtained from a 253 fb(-1) data sample that contains 275x10(6) B(B) over bar pairs that were collected near the Upsilon(4S) resonance with the Belle detector at the KEKB asymmetric energy e(+)e(-) collider. The statistical significance of the omega J/psi mass enhancement is estimated to be greater than 8 sigma.

    We have measured pi(+)pi(-) and K+K- production in two-photon collisions using 87.7 fb(-1) of data collected with the Belle detector at the asymmetric energy e(+)e(-) collider KEKB. The cross sections are measured to high precision in the two-photon center-of-mass energy (W) range between 2.4 GeV &lt; W &lt; 4.1 GeV and angular region broken vertical bar cos theta*broken vertical bar &lt; 0.6. The cross section ratio sigma(gamma gamma -&gt; K+K-)/sigma(gamma gamma -&gt; pi(+)pi(-)) is measured to be 0.89 +/- 0.04(stat.)+/- 0.15(syst.) in the range of 3.0 GeV &lt; W &lt; 4.1 GeV, where the ratio is energy-independent. We observe a sin(-4)theta* behavior of the cross section in the same W range. Production of chi(c0) and chi(c2) mesons is observed in both gamma gamma -&gt; pi(+)pi(-) and gamma gamma -&gt; K+K- modes. (c) 2005 Elsevier B.V. All rights reserved.

One of two B mesons is fully reconstructed in a CP-eigenstate or a flavor-eigenstate decay channel. The flavor of the accompanying B meson is identified from its decay products. From the distributions of the time interval between the two B meson decay points, we obtain sin2 phi(1)=0.728 +/- 0.056(stat)+/- 0.023(syst), vertical bar lambda vertical bar=1.007 +/- 0.041(stat)+/- 0.033(syst), tau(B)(0)=[1.534 +/- 0.008(stat)+/- 0.010(syst)] ps, tau(B)(+)=[1.635 +/- 0.011(stat)+/- 0.011(syst)] ps, tau(B)(+)/tau(B)(0)=1.066 +/- 0.008(stat)+/- 0.008(syst) and Delta m(d)=[0.511 +/- 0.005(stat)+/- 0.006(syst)] ps(-1). The results for sin2 phi(1) and vertical bar lambda vertical bar are consistent with the standard model expectations. The significance of the observed deviation from unity in the lifetime ratio exceeds 5 standard deviations.

    We report a study of the suppressed decays B - → [K +π -] DK - and B - → [K +π -] Dπ -, where [K +π -] D indicates that the K +π - pair originates from a neutral D meson. These decay modes are sensitive to the unitarity triangle angle φ 3. We use a data sample containing 275 × 10 6 BB̄ pairs recorded at the Y(4S) resonance with the Belle detector at the KEKB asymmetric e +e - storage ring. The signal for B - → [K +π -] DK - is not statistically significant, and we set a limit r B &lt
    0.27 at 90% confidence level, where r B is the magnitude of the ratio of amplitudes |A(B - → D̄ 0K -)/A(B - → D 0K -)|. We observe a signal with 6.4σ statistical significance in the related mode, B - → [K +π -] Dπ -. © 2005 The American Physical Society.

    We have searched for mixing in the Ddegrees-(D) over cap (0) D-0 system by measuring the decay-time distribution of D0 ! K(+)pi(-) decays. The analysis uses 90 fb(-1) of data collected by the Belle detector at the KEKB e(+) e(-) collider. We fit the decay-time distribution for the mixing parameters x(1) and y(1) and also for the parameter R-D, which is the ratio of the rate for the doubly-Cabibbo-suppressed decay D-0--&gt; K(+)pi(-) to that for the Cabibbo-favored decay D-0 --&gt; K- pi(+). We do these fits both assuming CP conservation and allowing for CP violation. We use a frequentist method to obtain a 95% C. L. region in the x(J2)- y(l) plane. Assuming no mixing, we measure R-D=(0: 381 +/- 0: 017 (+) (0.008)(-0.016))%.

    We present a measurement of the unitarity triangle angle phi(3) using a Dalitz plot analysis of the three-body decay of the neutral D meson from the B+/---&gt;(DK+/-)-K-(*) process. The method employs the interference between D-0 and (D) over bar (0) to extract both the weak and strong phases. We apply this method to a 140 fb(-1) data sample collected by the Belle experiment. The analysis uses the modes B+/---&gt;DK+/- and B+/---&gt;(DK+/-)-K-*, D-*--&gt;Dpi(0), where the neutral D meson decays into K(S)pi(+)pi(-). We obtain 146 signal candidates for B+/---&gt;DK+/- and 39 candidates for B+/---&gt;(DK+/-)-K-*. From a combined maximum likelihood fit to the B+/---&gt;DK+/- and B+/---&gt;(DK+/-)-K-* modes, we obtain phi(3)=77(-19degrees)(+degrees17)degrees (stat)+/-13degrees(syst)+/-11degrees(model). The corresponding 2 standard deviation interval is 26degrees&lt;phi(3)&lt;126degrees.

    We report a fully inclusive measurement of the flavor changing neutral current decay b--&gt;sgamma in the energy range 1.8 GeVless than or equal toE(gamma)(*)less than or equal to2.8 GeV, covering 95% of the total spectrum. Using 140 fb(-1), we obtain B(b--&gt;sgamma)=(3.55+/-0.32(-0.31-0.07)(+0.30+0.11))x10(-4), where the errors are statistical, systematic, and from theory corrections. We also measure the first and second moments of the photon energy spectrum above 1.8 GeV and obtain &lt;E-gamma&gt;=2.292+/-0.026+/-0.034 GeV and &lt;E-gamma(2)&gt;-&lt;E-gamma&gt;(2)=0.0305+/-0.0074+/-0.0063 GeV2, where the errors are statistical and systematic.

    We report measurements of time dependent decay rates for B-0((B) over bar (0))--&gt;D((*)-/+)pi(+/-) decays and extraction of CP violation parameters containing phi(3). Using fully reconstructed D((*))pi events from a 140 fb(-1) data sample collected at the Y(4S) resonance, we obtain the CP violation parameters for D(*)pi and Dpi decays, 2R(D)((*))pisin(2phi(1)+phi(3)+/-delta(D)((*))pi), where R(D)((*))pi is the ratio of the magnitudes of the doubly Cabibbo-suppressed and Cabibbo-favored amplitudes, and delta(D)((*))pi is the strong phase difference between them. Under the assumption of delta(D)((*))pi being close to either 0degrees or 180degrees, we obtain \2R(D)(*)pisin(2phi(1)+phi(3))\=0.060+/-0.040(stat)+/-0.019(syst) and \2R(Dpi)sin(2phi(1)+phi(3))\=0.061+/-0.037(stat)+/-0.018(syst).

    We report the first observation of CP violation in B(pp)(pp)(pp)(pp)(pp)(0+p- decays based on 152x106 U(4S)B (B) over bar decays collected with the Belle detector at the KEKB asymmetric-energy e+e- collider. We reconstruct a B0+p- CP eigenstate and identify the flavor of the accompanying B meson from its decay products. From the distribution of the time intervals between the two B meson decay points, we obtain A)(=+0.580.15(stat)0.07(syst) and S)(=-1.000.21(stat)0.07(syst). We rule out the CP-conserving case, A)(=S)(=0, at a level of 5.2 standard deviations. We also find evidence for direct CP violation with a significance at or greater than 3.2 standard deviations for any S) value.

    We have searched for neutrinoless tau lepton decays into three charged leptons using an 87.1 fb(-1) data sample collected with the Belle detector at the KEKB e(+)e(-) collider.

    We report measurements of the radiative decay B--&gt;K*gamma. The analysis is based on a data sample containing 85.0x10(6) B meson pairs collected by the Belle detector at the KEKB storage ring. We measure branching fractions of B(B-0--&gt;K*(0)gamma)=(4.01+/-0.21+/-0.17)x10(-5) and B(B+--&gt;K*(+)gamma)=(4.25+/-0.31+/-0.24)x10(-5), where the first and second errors are statistical and systematic, respectively. The isospin asymmetry between B-0 and B+ decay widths is measured to be Delta(0+)=+0.012+/-0.044+/-0.026, assuming an equal production rate for (BB)-B-0 $$($) over bar (0) and B+B- pairs from the Y(4S) resonance. We search for a partial rate asymmetry between CP conjugate modes, and find A(CP)(B--&gt;K*gamma)=-0.015+/-0.044+/-0.012.

A common feature of the observed decay modes is threshold peaking in baryon pair invariant mass.

    We report the measurement of an inclusive partial branching fraction for charmless semileptonic B decay and the extraction of \V-ub\. Candidates for B--&gt;X-u.nu are identified with a novel X-u reconstruction method based on neutrino reconstruction via missing 4-momentum and a technique called "simulated annealing." Based on 86.9 fb(-1) of data taken with the Belle detector, we obtain DeltaB(B--&gt;X-u.nu;M-X&lt;1.7 GeV/c(2),q(2)&gt;8.0 GeV2/c(2))=[7.37+/-0.89(stat)+/-1.12(syst)+/-0.55(b--&gt;c)+/-0.24(b--&gt;u)]x10(-4) and determine \V-ub\=[4.66+/-0.28(stat)+/-0.35(syst)+/-0.17(b--&gt;c)+/-0.08(b--&gt;u)+/-0.58(theory)]x10(-3).

    We report the observation of the decay D-0--&gt;phigamma with a statistical significance of 5.4sigma in 78.1 fb(-1) of data collected by the Belle experiment at the KEKB e(+)e(-) collider. This is the first observation of a flavor-changing radiative decay of a charmed meson. The Cabibbo- and color-suppressed decays D-0--&gt;phipi(0), phieta are also observed for the first time. We measure branching fractions B(D-0--&gt;phigamma)=[2.60(-0.61)(+0.70)(stat)(-0.17)(+0.15)(syst)]x10(-5), B(D-0--&gt;phipi(0))=[8.01+/-0.26(stat)+/-0.47(syst)]x10(-4), and B(D-0--&gt;phieta)=[1.48+/-0.47(stat)+/-0.09(syst)]x10(-4).

    We report results of a study of charmless B meson decays to three-body Kpipi, KKpi and KKK final states. Measurements of branching fractions for B decays to K(+(0))pi(+)pi(-), K+K+K-, (KK+K-)-K-0, (K+KSKS0)-K-0 and (KSKSKS0)-K-0-K-0 final states are presented. The decays B-0--&gt;(KK+K-)-K-0, B+--&gt;(K+KSKS0)-K-0 and B-0--&gt;(KSKSKS0)-K-0-K-0 are observed for the first time. We also report evidence for B+--&gt;K(+)K(-)pi(+) decay. For the three-body final states K(0)K(+)pi(-), K(S)(0)K(S)(0)pi(+), K(+)K(+)pi(-) and K(-)pi(+)pi(+), 90% confidence level upper limits are reported. Finally, we discuss the possibility of using the three-body B-0--&gt;(KSK+K-)-K-0 decay for CP violation studies. The results are obtained with a 78 fb(-1) data sample collected at the Y(4S) resonance by the Belle detector operating at the KEKB asymmetric energy e(+)e(-) collider.

    We present an improved measurement of CP-violation parameters in B(0)--&gt;phiK(S)(0), K(+)K(-)K(S)(0), and eta(&apos;)K(S)(0) decays based on a 140 fb(-1) data sample collected at the Y(4S) resonance with the Belle detector at the KEKB energy-asymmetric e(+)e(-) collider. One neutral B meson is fully reconstructed in one of the specified decay channels, and the flavor of the accompanying B meson is identified from its decay products. CP-violation parameters for each of the three modes are obtained from the asymmetries in the distributions of the proper-time intervals between the two B decays. We find that the observed CP asymmetry in the B--&gt;phiK(S)(0) decay differs from the standard model (SM) expectation by 3.5 standard deviations, while the other cases are consistent with the SM.

    We report results on the decay B---&gt;DCPK- and its charge conjugate using a data sample of 85.4x10(6) B (B) over bar pairs recorded at the Y(4S) resonance with the Belle detector at the KEKB asymmetric e(+)e(-) storage ring. Ratios of branching fractions of Cabibbo-suppressed to Cabibbo-favored processes are determined to be B(B---&gt;(DK-)-K-0)/B(B---&gt;D(0)pi(-))=0.077+/-0.005(stat)+/-0.006(syst), B(B---&gt;D1K-)/B(B---&gt;D(1)pi(-))=0.093+/-0.018(stat)+/-0.008(syst) and B(B---&gt;D2K-)/B(B---&gt;D(2)pi(-))=0.108+/-0.019(stat)+/-0.007(syst) where the indices 1 and 2 represent the CP=+1 and CP=-1 eigenstates of the D-0-(D) over bar (0) system, respectively. We find the partial-rate charge asymmetries for B---&gt;DCPK- to be A(1)=0.06+/-0.19(stat)+/-0.04(syst) and A(2)=-0.19+/-0.17(stat)+/-0.05(syst).

    We have operated successfully glass Resistive Plate Counters (RPC) at the BELLE experiment by using a nonflammable gas mixture of 30% argon, 8% butane-silver and 62% freon, HFC-134a. This freon is nonozone depleting freon, but a freon has a high global warming potential in general. Thus a gas mixture for RPC might be desired to be freonless in the near future. We have tested the performance of glass RPC operated in streamer mode with a nonfreon gas mixture of argon, butane, CO2 and/or O-2 gases, and found an efficiency of about 90%.

    Neutrinoless tau-lepton decays into either three leptons (tau- --&gt; l(1)(-)l(2)l(3)) or one lepton and one K-S(0) meson(tau- --&gt; l(-)K(S)(0)) where lepton means either an electron or muon, have been searched for using 48.6 fb(-1) of data collected with the Belle detector at the KEKB e(+)e(-) collider. No evidence for candidate decays are found in any channel. Therefore we set 90% confidence level upper limits on the branching fraction for 8 different decay modes. These limits are more stringent than those set previously and reach to the 10(-7) level.
