    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.

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

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

    We report the first measurement of the Q2 distribution of X(3915) produced by single-tag two-photon interactions. The decay mode used is X(3915)→J/ψω. The covered Q2 region is from 1.5 (GeV/c)2 to 10.0 (GeV/c)2. We observe 7.9±3.1(stat)±1.5(syst) events, where we expect 4.1±0.7 events based on the Q2=0 result from the no-tag two-photon process, extrapolated to higher Q2 region using the cc¯ model of Schuler, Berends, and van Gulik. The shape of the distribution is also consistent with this model; we note that statistical uncertainties are large.

    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.

    Theories beyond the standard model often predict the existence of an additional neutral boson, the Z′.Using data collected by the Belle II experiment during 2018 at the SuperKEKB collider, we perform the first searches for the invisible decay of a Z′ in the process e⁺e⁻ → μ⁺μ⁻Z′ and of a lepton-flavor-violating Z′ in e⁺e⁻ →e±μ∓Z′. We do not find any excess of events and set 90% credibility level upper limits on the cross sections of these processes. We translate the former, in the framework of an Lμ − Lτ theory, into upper limits on the Z′ coupling constant at the level of 5 × 10⁻² − 1 for Mz′ ≤ 6 GeV/c².

    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.

    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 the results of a search for the decay $B^0 \to X(3872)(\to J/\psi
    \pi^+ \pi^-) \gamma$. The analysis is performed on a data sample corresponding
    to an integrated luminosity of $711\,{\rm fb}^{-1}$ and containing $772 \times
    10^6 B\bar{B}$ pairs, collected with the Belle detector at the KEKB
    asymmetric-energy $e^+ e^-$ collider running at the $\Upsilon(4S)$ resonance
    energy. We find no evidence for a signal and place an upper limit of
    $\mathcal{B}(B^0 \to X(3872)\gamma)\times \mathcal{B}(X(3872) \to J/\psi \pi^+
    \pi^-) < 5.1 \times 10^{-7}$ at 90% confidence level.

    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 present the first measurements of the absolute branching fractions of
    $\Xi_c^+$ decays into $\Xi^- \pi^+ \pi^+$ and $p K^- \pi^+$ final states. Our
    analysis is based on a data set of $(772\pm 11)\times 10^{6}$ $B\bar{B}$ pairs
    collected at the $\Upsilon(4S)$ resonance with the Belle detector at the KEKB
    $e^+e^-$ collider. We measure the absolute branching fraction of $\bar{B}^{0}
    \to \bar{\Lambda}_{c}^{-} \Xi_{c}^{+}$ with the $\Xi_c^+$ recoiling against
    $\bar{\Lambda}_c^-$ in $\bar{B}^0$ decays resulting in ${\cal B}(\bar{B}^{0}
    \to \bar{\Lambda}_{c}^{-} \Xi_{c}^{+}) = [1.16 \pm 0.42(\rm stat.) \pm 0.15(\rm
    syst.)] \times 10^{-3}$. We then measure the product branching fractions ${\cal
    B}(\bar{B}^{0} \to \bar{\Lambda}_c^- \Xi_c^+){\cal B}(\Xi_c^+ \to \Xi^- \pi^+
    \pi^+)$ and ${\cal B}(\bar{B}^{0} \to \bar{\Lambda}_c^- \Xi_c^+){\cal
    B}(\Xi_c^+ \to p K^- \pi^+)$. Dividing these product branching fractions by
    $\bar{B}^{0} \to \bar{\Lambda}_{c}^{-} \Xi_{c}^{+}$ yields: ${\cal B}(\Xi_c^+
    \to \Xi^- \pi^+ \pi^+) = [2.86 \pm 1.21(\rm stat.) \pm 0.38(\rm syst.)]\%$ and
    ${\cal B}(\Xi_c^+ \to p K^- \pi^+)=[0.45 \pm 0.21(\rm stat.) \pm 0.07(\rm
    syst.)]\%$. Our result for ${\cal B}(\Xi_c^+ \to \Xi^- \pi^+ \pi^+)$ can be
    combined with $\Xi_c^+$ branching fractions measured relative to $\Xi_c^+ \to
    \Xi^- \pi^+ \pi^+$ to set the absolute scale for many $\Xi_c^+$ branching
    fractions.

    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 &quot;penguin&quot; 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 &quot;tree&quot; 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 measurements of the branching fractions of the decays Lambda(+)(c) -> Sigma(+)pi(-)pi(+), Lambda(+)(c) -> Sigma(0)pi(+)pi(0) and Lambda(+)(c) -> Sigma(+)pi(0)pi(0) relative to the reference channel Lambda(+)(c) -> pK(-)p(+). The analysis is based on the full data sample collected at and near the gamma(4S) resonance by the Belle detector at the KEKB asymmetric-energy ethorne-collider, corresponding to an integrated luminosity of 711 fb(-1). We measure B(Lambda(+)(c) -> Sigma(+)pi(-)pi(+))/B(Lambda(+)(c) -> pK(-)pi(+)) = 0.719 +/- 0.003 +/- 0.024, B(Lambda(+)(c) -> Sigma(0) pi(+)pi(0))/B(Lambda(+)(c) -> pK(-)pi(+)) = 0.575 +/- 0.005 +/- 0.036 and B(Lambda(+)(c) -> Sigma(+)pi(0)pi(0))/B(Lambda(+)(c) -> pK(-)pi(+)) = 0.247 +/- 0.006 +/- 0.019. The listed uncertainties are statistical and systematic, respectively.

    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 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.

    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.

    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.

    We search for the $J^{PC}=0^{--}$ and $1^{+-}$ light tetraquark states with
    masses up to 2.46~GeV/$c^2$ in $\Upsilon(1S)$ and $\Upsilon(2S)$ decays with
    data samples of $(102\pm 2)$ million and $(158\pm 4)$ million events,
    respectively, collected with the Belle detector. No significant signals are
    observed in any of the studied production modes, and 90\% credibility level
    (C.L.) upper limits on their branching fractions in $\Upsilon(1S)$ and
    $\Upsilon(2S)$ decays are obtained. The inclusive branching fractions of the
    $\Upsilon(1S)$ and $\Upsilon(2S)$ decays into final states with $f_1(1285)$ are
    measured to be ${\cal B}(\Upsilon(1S)\to f_1(1285)+anything)=(46\pm28({\rm
    stat.})\pm13({\rm syst.}))\times 10^{-4}$ and ${\cal B}(\Upsilon(2S)\to
    f_1(1285)+anything)=(22\pm15({\rm stat.})\pm6.3({\rm syst.}))\times 10^{-4}$.
    The measured $\chi_{b2} \to J/\psi + anything$ branching fraction is measured
    to be $(1.50\pm0.34({\rm stat.})\pm0.22({\rm syst.}))\times 10^{-3}$, and 90\%
    C.L. upper limits for the $\chi_{b0,b1} \to J/\psi + anything$ branching
    fractions are found to be $2.3\times 10^{-3}$ and $1.1\times 10^{-3}$,
    respectively. For ${\cal B}(\chi_{b1} \to \omega + anything)$, the branching
    fraction is measured to be $(4.9\pm1.3({\rm stat.})\pm0.6({\rm syst.}))\times
    10^{-2}$. %($<3.68\times 10^{-2}$ at 90\% C.L.). All results reported here are
    the first measurements for these modes.

    We report a search for a dark vector gauge boson U' that couples to quarks in the decay chain D*(+) -&gt; D-0 pi(+), D-0 -&gt; K-S(0) eta, eta -&gt; U'gamma, U' -&gt; pi(+)pi- No signal is found and we set a mass-dependent limit on the baryonic fine structure constant of 10(-3)-10(-2) in the U' mass range of 290 to 520 MeV/c(2). This analysis is based on a data sample of 976 fb(-1) collected by the Belle experiment at the KEKB asymmetric-energy e(+)e(-) collider.

    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 a measurement of the B-0 -&gt; psi(2S)pi(0) branching fraction based on the full Upsilon(4S) data set of 772 x 10(6) B (B) over bar pairs collected by the Belle detector at the KEKB asymmetric-energy e(+)e(-) collider. We obtain B(B-0 -&gt; psi(2S)pi(0)) = (1.17 +/- 0.17(stat) +/- 0.08(syst)) x 10(-5). The result has a significance of 7.2 standard deviations and is the first observation of the decay B-0 -&gt; psi(2S)pi(0).

    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).

    We use 772 x 10(6) B (B) over bar meson pairs collected at the gamma(4S) resonance with the Belle detector to measure the branching fraction for (B) over bar -&gt; X-s gamma Our measurement uses a sum-of-exclusives approach in which 38 of the hadronic final states with strangeness equal to +1, denoted by X-s, are reconstructed. 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 present a search for the rare leptonic decays B+ -&gt; e(+)nu(e) and B+ -&gt; mu(+) nu(mu) using the full Upsilon(4S) data sample of 772 x 10(6) B (B) over bar pairs collected with the Belle detector at the KEKB asymmetric-energy e(+)e(-) collider. One of the B mesons from the Upsilon(4S) -&gt; B (B) over bar decay is fully reconstructed in a hadronic mode, while the recoiling side is analyzed for the signal decay. We find no evidence of a signal in any of the decay modes. Upper limits of the corresponding branching fractions are determined as beta(B+ -&gt; e(+)nu(e)) &lt; 3.5 x 10(-6) and beta(B+ -&gt; mu(+)nu(mu)) &lt; 2.7 x 10(-6) at 90% confidence level.

    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 also observe a deviation of the DsK invariant-mass distribution from the three-body phase-space model for both studied decays.

    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 report the first observation of the Cabibbo-suppressed decays Xi(0)(c) -&gt; Xi K--(+), Xi(0)(c) -&gt; Lambda K+K- and Xi(0)(c) -&gt; Lambda phi, using a data sample of 711 fb(-1) collected at the Y(4S) resonance with the Belle detector at the KEKB asymmetric-energy e(+)e(-) collider. We measure the ratios of branching fractions to be B(Xi(0)(c)-&gt;Xi K--(+))/B(Xi(0)(c)-&gt;Xi(-)pi(+)) = (2.75 +/- 0.51 +/- 0.25) x 10(-2), B(Xi(0)(c)-&gt;Lambda K+K-)/B(Xi(0)(c)-&gt;Xi(-)pi(+)) = (2.86 +/- 0.61 +/- 0.37) x 10(-2) and B(Xi(0)(c)-&gt;Lambda phi)/B(Xi(0)(c)-&gt;Xi(-)pi(+)) = (3.43 +/- 0.58 +/- 0.32) X 10(-2), where the first uncertainty is statistical and the second is systematic.

    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.

    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 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.

    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 measurements of the branching fractions and CP asymmetries for B-+/- -&gt; eta h(+/-) (h = K or pi) and the observation of the decay B-0 -&gt; eta K-0 from the final data sample of 772 x 10(6) B (B) over bar pairs collected with the Belle detector at the KEKB asymmetric-energy 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 search for lepton flavor and lepton number violating tau decays into a lepton (l = electron or muon) and two charged mesons (h, h&apos; = pi(+/-) or K(+/-)), tau(-) -&gt; l(-)h(+)h&apos;(-) and tau- -&gt; l(+)h(-)h&apos;(-), using 671 fb(-1) of data collected with the Belle detector at the KEKB asymmetric-energy e(+)e(-) collider. We obtain 90% C.L. upper limits on the branching fractions in the range (4.4-8.8) x 10(-8) for tau -&gt; ehh&apos;, and (3.3-16) x 10(-8) for tau -&gt; mu hh&apos; processes. These results improve upon previously published upper limits by factors between 1.6 to 8.8. (C) 2009 Elsevier B.V. All rights reserved.

    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 new measurements of the decays B+→ρ+γ, B0→ρ0γ, and B0→ωγ using a data sample of 657×106 B meson pairs accumulated with the Belle detector at the KEKB e+e- collider. We measure branching fractions B(B+→ρ+γ)=(8.7-2.7-1. 1+2.9+0.9)×10-7, B(B0→ρ0γ)=(7.8-1.6-1.0+1.7+0.9)×10- 7, and B(B0→ωγ)=(4.0-1.7+1.9±1.3)×10-7. We also report the isospin asymmetry Δ(ργ)=-0.48-0.19-0.09+0.21+0.08 and the first measurement of the direct CP-violating asymmetry ACP(B+→ρ +γ)=-0.11±0.32±0.09, where the first and second errors are statistical and systematic, respectively. © 2008 The American Physical Society.

    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.

    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 report the first observation of e(+)e(-) -&gt; Y(1S)pi(+)pi(-), Upsilon(2S)pi(+)pi(-), and first evidence for e(+)e(-) -&gt; Y(3S)pi(+)pi(-), Y(1S)K(+)K(-), near the peak of the Y(5S) resonance at root s similar to 10.87 GeV. The results are based on a data sample of 21.7 fb(-1) collected with the Belle detector at the KEKB e(+)e(-) collider. 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 search for the radiative penguin decays B(s)(0)-&gt;phi gamma and B(s)(0)-&gt;gamma gamma in a 23.6 fb(-1) data sample collected at the Upsilon(5S) resonance with the Belle detector at the KEKB e(+)e(-) asymmetric-energy collider. We observe for the first time a radiative penguin decay of the B(s)(0) meson in the B(s)(0)-&gt;phi gamma mode and we measure B(B(s)(0)-&gt;phi gamma)=(57(-15)(+18)(stat)(-11)(+12)(syst))x10(-6). No significant B(s)(0)-&gt;gamma gamma signal is observed and we set a 90% confidence level upper limit of B(B(s)(0)-&gt;gamma gamma)&lt; 8.7x10(-6).

    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.

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 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 the first observation of B-0 -&gt; J/psi eta decay. These results are obtained from a data sample that contains 449x10(6) B (B) over bar pairs accumulated at the Upsilon(4S) resonance with the Belle detector at the KEKB asymmetric-energy e(+)e(-) collider. We observe a signal with a significance of 8.1 sigma and obtain a branching fraction of (9.5 +/- 1.7(stat)+/- 0.8(syst))x10(-6).

    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 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.

    We report evidence for the exclusive two-body charmless hadronic B meson decay B -&gt;eta(')pi, and improved measurements of B -&gt;eta K-'. 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). We also find the ratio of B(B+-&gt;eta K-'(+))/B(B-0 -&gt;eta K-'(0))=1.17 +/- 0.08(stat)+/- 0.03(syst) and measure the direct CP asymmetries for the charged modes.

    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 report the observation of the flavor-changing neutral current process b -&gt; d gamma using a sample of 386 x 10(6) B meson pairs accumulated by the Belle detector at the KEKB e(+)e(-) collider. We measure branching fractions for the exclusive modes B- -&gt; rho(-)gamma, (B) over bar (0) -&gt; rho(0)gamma, and (B) over bar (0) -&gt; omega gamma. Assuming that these three modes are related by isospin, we find B((B) over bar -&gt; (rho, omega)gamma) = (1.32(-0.31)(+0.34)(stat)(-0.09)(+0.10)(syst)) x 10(-6) with a significance of 5.1 sigma. This result is used to determine the ratio of Cabibbo-Kobayashi-Maskawa matrix elements vertical bar V-td/V-ts vertical bar to be 0.199(-0.025)(+0.026)(exp)(-0.015)(+0.018)(theor).

    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.

Measurements of branching fractions for quasi-two-body decays to scalar-pseudoscalar states: B+→f0(980)K+, B+→K0*(1430)0π+, and to vector-pseudoscalar states: B+→K*(892)0π+, B+→ρ0K+, B+→ K+ are presented. Upper limits on decays to some pseudoscalar-tensor final states are reported. We also report the measurement of the B+→χc0K+ branching fraction in two χc0 decays channels: χc0→π+π- and χc0→K+K-. © 2005 The American Physical Society.

    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.

    We report the observation of a near-threshold enhancement in the omega J/psi invariant mass distribution for exclusive B -&gt; K omega J/psi decays. 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.

    We present a precise measurement of the standard model CP-violation parameter sin2 phi(1), the direct CP violation parameter vertical bar lambda vertical bar, the lifetimes of charged and neutral B mesons and their ratio, and the B-0-(B) over bar (0) mixing parameter Delta m(d) based on a sample of 152x10(6) B(B) over bar pairs collected at the Upsilon(4S) resonance with the Belle detector at the KEKB asymmetric-energy e(+)e(-) collider. 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.

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 report a measurement of the Xi(c)(+) and Xi(c)(0) baryon masses, and the branching ratios for various Xi(c) decays, using 140 fb(-1) of data collected by the Belle experiment at the KEKB e(+)e(-) collider. The mass splitting m(Xic0) - m(Xic+) is found to be 2.9 +/- 0.5 MeV/c(2); this measurement is three times as precise as the current world average. We measure the branching ratios Gamma(Xi(c)(+) --&gt; LambdaK(-)pi(+)pi(+))/Gamma(Xi(c)(+) --&gt; Xi(-)pi(+)pi(+)) = 0.32 +/- 0.03 +/- 0.02 and Gamma(Xi(c)(0) --&gt; pK(-)K(-)pi(+))/Gamma(Xi(c)(0) --&gt; Xi(-)pi(+)) = 0.33 +/- 0.03 +/- 0.03, with improved precision, and measure Gamma(Xi(c)(+) --&gt; pK(S)(0)K(S)(0))/Gamma(Xi(c)(+) --&gt; Xi(-)pi(+)pi(+)) = 0.087 +/- 0.016 +/- 0.014, Gamma(Xi(c)(0) --&gt; LambdaK(-)pi(+))/Gamma(Xi(c)(0) --&gt; Xi(-)pi(+)) = 1.07 +/- 0.12 +/- 0.07 and Gamma(Xi(c)(0) --&gt; LambdaK(S)(0))/Gamma(Xi(c)(0) --&gt; Xi(-)pi(+)) = 0.21 +/- 0.02 +/- 0.02 for the first time.

    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 first measurements of e(+)e(-)--&gt;D-(*D-)+(()*()-) processes far above threshold. The cross sections for e(+)e(-)--&gt;DT*+DL*(-) and e(+)e(-)--&gt;D+DT*(-) at roots similar or equal to 10.6 GeV/c(2) are measured to be 0.55+/-0.03+/-0.05 and 0.62+/-0.03+/-0.06 pb, respectively. We set upper limits on the cross sections for e(+)e(-)--&gt;D-T*D-+(T)*(-), e(+)e(-)--&gt;D-L*D-+(L)*(-), e(+)e(-)--&gt;D+DL*(-), and e(+)e(-)--&gt;D+D- processes. The analysis is based on 88.9 fb(-1) of data collected by the Belle experiment at the KEKB e(+)e(-) asymmetric collider.

    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 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. Since the number of signal candidate events is compatible with that expected from the background, we set 90% confidence level upper limits on the branching fractions in the range (1.9-3.5) x 10(-7) for various decay modes tau(-) --&gt; l(-)l(+)l(-) where l represents e or mu.

    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.

    We report the first observation of a b--&gt;u type charmless baryonic B decay, B+--&gt;p (p) over bar pi(+), as well as b--&gt;s type B-0--&gt;p (p) over barK(0) and B+--&gt;p (p) over barK(*+) decays. The analysis is based on a 78 fb(-1) data sample recorded on the Y(4S) resonance with the Belle detector at KEKB. We find B(B+--&gt;p (p) over bar pi(+))=(3.06(-0.62)(+0.73)+/-0.37)x10(-6), B(B-0--&gt;p (p) over barK(0))=(1.88(-0.60)(+0.77)+/-0.23)x10(-6), and B(B+--&gt;p (p) over barK(*+))=(10.3(-2.8-1.7)(+3.6+1.3))x10(-6). We also update B(B+--&gt;p (p) over barK(+))=(5.66(-0.57)(+0.67)+/-0.62)x10(-6) and present an upper limit on B(B-0--&gt;p (p) over barK(*0)) at the 90% confidence level. 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.

    We report a precise determination of the B-0-(B) over bar (0) mixing parameter Deltam(d) based on the time evolution of same-sign and opposite-sign dilepton yields in Y(4S) decays. Data were collected with the Belle detector at KEKB. Using data samples of 29.4 fb(-1) recorded at the Y(4S) resonance and 3.0 fb(-1) recorded at an energy 60 MeV below the resonance, we measure Deltam(d)=[0.503+/-0.008(stat)+/-0.010(syst)] ps(-1). From the same analysis, we also measure the ratio of charged and neutral B meson production at the Y(4S), f(+)/f(0)=1.01+/-0.03(stat)+/-0.09(syst), and CPT violation parameters in B-0-(B) over bar (0) mixing, R(cos theta)=0.00+/-0.12(stat)+/-0.01(syst) and J(cos theta)=0.03+/-0.01(stat)+/-0.03(syst).

    We present a measurement of CP-violation parameters in the b--&gt;s (q) over barq penguin transitions (q=s,u,d) based on a 78 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 reconstructed in the phiK(S)(0), (K+K-KS0), or eta'K-S(0) decay channel, 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.

    K (+) K- production in two-photon collisions has been studied using a large data sample of 67 fb(-1) accumulated with the Belle detector at the KEKB asymmetric e (+) e(-) collider. We have measured the cross section for the process gammagamma --&gt; K+K- for center-of-mass energies between 1.4 and 2.4 GeV, and found three new resonant structures in the energy region between 1.6 and 2.4 GeV. The angular differential cross sections have also been measured.

    We have searched for a CP violation signature arising from an electric dipole moment (d(tau)) of the tau lepton in the e(+)e(-) --&gt; tau(+)tau(-) reaction. Using an optimal observable method and 29.5 fb(-1) of data collected with the Belle detector at the KEKB collider at roots- = 10.58 GeV, we find Re(d(tau)) = (1.15 +/- 1.70) x 10(-17) e cm and Im(d(tau)) = (-0.83+/-0.86) &lt; 0.8 x 10(-17) e cm and set the 95% confidence level limits -2.2 x 10(-17) &lt; Re(dT) &lt; 4.5 x 10(-17) e cm and -2.5 x 10(-17) &lt; Im(dr) &lt; 0.8 x 10(-17) e cm.

    We present an improved measurement of [Formula presented]-violation parameters in [Formula presented], [Formula presented], and [Formula presented] decays based on a [Formula presented] data sample collected at the [Formula presented] resonance with the Belle detector at the KEKB energy-asymmetric [Formula presented] collider. One neutral [Formula presented] meson is fully reconstructed in one of the specified decay channels, and the flavor of the accompanying [Formula presented] meson is identified from its decay products. [Formula presented]-violation parameters for each of the three modes are obtained from the asymmetries in the distributions of the proper-time intervals between the two [Formula presented] decays. We find that the observed [Formula presented] asymmetry in the [Formula presented] decay differs from the standard model (SM) expectation by 3.5 standard deviations, while the other cases are consistent with the SM. © 2003 The American Physical Society.

    We report a precise determination of the [Formula Presented] mixing parameter [Formula Presented] based on the time evolution of same-sign and opposite-sign dilepton yields in [Formula Presented] decays. Data were collected with the Belle detector at KEKB. Using data samples of 29.4 [Formula Presented] recorded at the [Formula Presented] resonance and 3.0 [Formula Presented] recorded at an energy 60 MeV below the resonance, we measure [Formula Presented] From the same analysis, we also measure the ratio of charged and neutral B meson production at the [Formula Presented] [Formula Presented] and CPT violation parameters in [Formula Presented] mixing, [Formula Presented] and [Formula Presented]. © 2003 The American Physical Society.

    We present the first measurement of decay amplitudes in [Formula presented] and measurements of branching fractions in [Formula presented] decays based on [Formula presented] of data recorded at the [Formula presented] resonance with the Belle detector at the KEKB [Formula presented] storage ring. The decay amplitudes for the different [Formula presented] helicity states are measured from the angular distributions of final state particles in the transversity basis.

    We report the results of a study of two-body B meson decays to the complete set of Kpi, pipi, and K (K) over bar final states. The study is performed on a data sample of 31.7+/-0.3 million B (B) over bar events recorded on the Y(4S) resonance by the Belle experiment at KEKB. We observe significant signals in all Kpi final states and in the pi(+)pi(-) and pi(+)pi(0) final states. We set limits on the pi(0)pi(0) and K (K) over bar final states. A search is performed for partial-rate asymmetries between conjugate states for flavor-specific final states.

    We present a measurement of the electron spectrum from inclusive semileptonic B decay, using 5.1 fb(-1) of Y(4S) data collected with the Belle detector. A high-momentum lepton tag was used to separate the semileptonic B decay electrons from secondary decal electrons. We obtained the branching fraction, B(B --&gt; Xe(+)v) = (10.90 +/- 0.12 +/- 0.49)%, with minimal model dependence, From this measurement, we derive a value for the Cabibbo-Kobayashi-Maskawa matrix element [V(cb)] =0.0408 +/- 0.0010(exp) 0.0025(th).

    We present measurements of CP-violating parameters in B-0 ((B) over bar (0)) --&gt; eta'K-S(0) and B+/- --&gt; eta'K+/- decays based on a 41.8 fb(-1) data sample collected at the gamma(4S) resonance with the Belle detector at the KEKB asymmetric-energy e(+)e(-) collider. We fully reconstruct one neutral B meson as a B-0((B) over bar (0)) --&gt; eta'K-S(0) CP eigenstate and identify the flavor of the accompanying B from its decay products. From the distribution of proper time intervals between pairs of B meson decay points, we obtain the CP-violating asymmetry parameters S-eta'KS(0) = 0.28+/-0.55(stat)(-0.08)(+0.07)(syst), and A(eta'KS)(0) = 0.13+/-0.32(stat)(-0.06)(+0.09)(syst). We also reconstruct charged B+/- --&gt; eta'K+/- decays and determine a direct- CP-violating asymmetry value of A(eta'K)(+/-) = (-1.5+/-7.0(stat) +/- 0.9(syst))%.

    We present an improved measurement of the standard model CP violation parameter sin 2phi(1) (also known as sin 2beta) based on a sample of 85x10(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/psiK(S)(0), psi(2S)K(S)(0), chi(c1)K(S)(0), eta(c)K(S)(0), J/psiK*(0), or J/psiK(L)(0) CP-eigenstate decay channel and the flavor of the accompanying B meson is identified from its decay products. From the asymmetry in the distribution of the time interval between the two B meson decay points, we obtain sin 2phi(1)=0.719+/-0.074(stat)+/-0.035(syst).

    This paper describes the muon identification method and its performance in the Belle experiment at KEKB. Muon and hadron likelihood are calculated for each track using its range and transverse scattering in the K-L-and-muon detector (KLM). We apply a cut on the normalized muon likelihood L-mu to identify the track as a muon. Above the detection threshold of 0.6 GeV/c, the measured muon detection efficiency and pion fake rate are approximately constant for momenta greater than 1.0 and 1.5 GeV/c, respectively. Between 1.0 and 3.0 GeV/c, the averaged muon detection efficiency is 89% and the pion fake rate per track is 1.4% over the KLM acceptance, using the standard selection criterion L-mu &gt; 0.9.

    The production of the chi(c2) charmonium state in two-photon collisions has been measured with the Belle detector at the KEKB e(+)e(-) collider. A clear signal for chi(c2) --&gt; gammaJ/psi, J/psi --&gt; l(+)l(-) is observed in a 32.6 fb(-1) data sample accumulated at center-of-mass energies near 10.6 GeV, and the product of its two-photon decay width and branching fraction is determined to be Gammagammagamma(chi(c2))B(chi(c2) --&gt; gammaJ/psi)B(J/psi --&gt; l(+)l(-)) = 13.5 +/- 1.3(stat.) +/- 1.1(syst.) eV.

    The branching fractions and the decay amplitudes of B --&gt; J/psiK* decays are measured in a 29.4 fb(-1) data sample collected with the Belle detector at the KEKB electron-positron collider. The decay amplitudes of helicity states of the J/psiK* system are determined from the full angular distribution of the final state particles in the transversity basis. The branching fractions are measured to be (1.29 +/- 0.05 +/- 0.13) x 10(-3) for neutral mesons and (1.28 +/- 0.07 +/- 0.14) x 10(-3) for charged mesons. The measured longitudinal and transverse (perpendicular to the transversity plane) amplitudes are \A(0)\(2) = 0.62 +/- 0.02 +/- 0.03 and \A(perpendicular to)\(2) = 0.19 +/- 0.02 +/- 0.03, respectively. The value of \A(perpendicular to)\(2) shows that the CP even component dominates in the B-0 --&gt; J/psiK*(0)(K(S)pi(0)) decay. (C) 2002 Elsevier Science B.V. All rights reserved.

    We present a measurement of the Cabibbo-Kobayashi-Maskawa (CKM) matrix element \V-cb\ using a 10.2 fb(-1) data sample recorded at the gamma(4S) resonance with the Belle detector at the KEKB asymmetric e(+)e(-) storage ring. By extrapolating the differential decay width of the (B) over bar (0) --&gt; D*(+)e(-)(v) over bar decay to the kinematic limit at which the D*(+) is at rest with respect to the (B) over bar (0,) we extract the product of \V-cb\ with the normalization of the decay form factor F(1), \V-cb\F(1) = (3.54 +/- 0.19 +/- 0.18) x 10(-2), where the first error is statistical and the second is systematic. A value Of \V-cb\ = (3.88 +/- 0.21 +/- 0.20 +/- 0.19) x 10(-2) is obtained using a theoretical calculation of F(l), where the third error is due to the theoretical uncertainty in the value of F(l). The branching fraction B((B) over bar (0) --&gt; D*(+)e(-) (v) over bar) is measured to be (4.59 +/- 0.23 +/- 0.40) x 10(-2). (C) 2002 Elsevier Science B.V. All rights reserved.

    We present a measurement of the branching fraction for the semileptonic B decay (B) over bar (0) --&gt; D(+)l(-)(v) over bar, where l(-) can be either an electron or a muon. We find Gamma((B) over bar (0) --&gt; D(+)l(-)(v) over bar) = (13.79 +/- 0.76 +/- 2.51) ns(-1), and the resulting branching fraction B((B) over bar (0) --&gt; D(+)e(-)(v) over bar) = (2.13 +/- 0.12 +/- 0.39)%, where the first error is statistical and the second systematic. We also investigate the (B) over bar (0) --&gt; D(+)l(-)(v) over bar form factor and the implications of the result for \V(cb)\. From a fit to the differential decay distribution we obtain the rate normalization \V(cb)\F(D)(1) = (4.11 +/- 0.44 +/- 0.52) X 10(-2). Using a theoretical calculation of F(D)(1), the Cabibbo-Kobayashi-Maskawa matrix element \V(cb)\ = (4.19 +/- 0.45 +/- 0.53 +/- 0.30) x 10(-2) is obtained, where the last error comes from the theoretical uncertainty of F(D)(1). The results are based on a data sample of 10.2 fb(-1) recorded at the gamma(4S) resonance with the Belle detector at the KEKB e(+)e(-) collider. (C) 2002 Elsevier Science B.V. All rights reserved.

    We present measurements of the Cabibbo-suppressed decays Lambda(c)(+) --&gt; Lambda(0)K(+) and Lambda(c)(+) --&gt; Sigma(0)K(+) (both first observations), Lambda(c)(+) --&gt; Sigma(+)K(+)pi(-) (seen with large statistics for the first time), Lambda(c)(+) --&gt; pK(+)K(-) and Lambda(c)(+) --&gt; pphi (measured with improved accuracy). Improved branching ratio measurements for the decays Lambda(c)(+) --&gt; Sigma(+)K(+)K(-) and Lambda(c)(+) --&gt; Sigma(+)phi, which are attributed to NV-exchange diagrarns, are shown. We also present the first evidence for Lambda(c)(+) --&gt; Xi(1690)(0)K(+) and set an upper limit on the non-resonant decay Lambda(c)(+) --&gt; Sigma(+)K(+)K(-). This analysis was performed using 32.6 fb(-1) of data collected by the Belle detector at the asymmetric e(+)e(-) collider KEKB, (C) 2002 Elsevier Science B.V. All rights reserved.

    We present a measurement of the [Formula presented] mixing parameter [Formula presented] using neutral [Formula presented] meson pairs in a [Formula presented] data sample collected at the [Formula presented] resonance with the Belle detector at the KEKB asymmetric-energy [Formula presented] collider. We exclusively reconstruct one neutral [Formula presented] meson in the semileptonic [Formula presented] decay mode and identify the flavor of the accompanying [Formula presented] meson from its decay products. From the distribution of the time intervals between the two flavor-tagged [Formula presented] meson decay points, we obtain [Formula presented], where the first error is statistical and the second error is systematic. © 2002 The American Physical Society.

    We report the first observation of the decay [Formula presented] with the Belle detector at the KEKB [Formula presented] Collider operated at the [Formula presented] resonance. The sum of branching fractions [Formula presented] is measured to be [Formula presented] using the full reconstruction method where both charmed mesons from [Formula presented] decays are reconstructed. A consistent value [[Formula presented]] is obtained using a partial reconstruction technique that uses only the slow pion from the [Formula presented] decay and a fully reconstructed [Formula presented] to reconstruct the [Formula presented]. © 2002 The American Physical Society.

    We report the first observation of a [Formula presented] meson decay that is not accessible by a direct spectator process. The channel [Formula presented] is found in a sample of [Formula presented] [Formula presented] events, collected with the Belle detector at KEKB, with a branching fraction [Formula presented]. We also obtain evidence for the [Formula presented] decay with branching fraction [Formula presented]. This value may be used to extract a model-dependent value of [Formula presented]. © 2002 The American Physical Society.

    We have operated successfully glass resistive plate counters in the streamer mode at the BELLE experiment by using a nonflammable gas mixture of argon 30 %, butane-silver 8 %, and freon, HFC-134a 62 %. This freon is non-ozone-depleting but has a high global warming potential (1300 times higher than that of CO2). Thus freon gases might be unusable in the near future. We tested the performance of a glass resistive plate counter operated in the streamer mode with an alternative gas mixtures of argon, butane, CO2, and/or O-2 gases and found an efficiency of about 90 %.

    We have tested the performance of glass RPC operated in streamer mode with the gas mixture containing SF, instead of freon, HFC-134a. By using a small amount of SF,, we could operate the RPCs at a much lower high voltage with comparable performance to the HFC-134a mixture except for having a narrower efficiency plateau. The feasibility for using the SF6 mixture is discussed. (C) 2000 Elsevier Science B.V. All rights reserved.

    This document presents the measurement of $B^0$ meson lifetimes using the
    2019 Belle II dataset that corresponds to an integrated luminosity of $8.7 \pm
    0.2$ fb$^{-1}$. Each candidate is fully reconstructed with hadronic decay final
    states on the signal side, while the rest-of-event technique allows to infer
    the decay vertex position on the other (tag) side. $B^0$ lifetime is extracted
    from an unbinned maximum likelihood fit to the distribution of the difference
    between the signal side $B^0$ candidate and the tag side decay times. The
    measured lifetime is $\tau_{B^0} = 1.48 \pm 0.28 \pm 0.06 $ ps, where the first
    uncertainty is statistical and the second is systematic.

    In the forward end-cap of the Belle II spectrometer, a proximity focusing Ring Imaging Cherenkov counter with an aerogel radiator will be installed. The detector will occupy a limited space inside solenoid magnet with longitudinal field of 1.5 T. It will consist of a double layer aerogel radiator, an expansion volume and a photon detector. 420 Hamamatsu hybrid avalanche photo sensors with 144 channels each will be used to read out single Cherenkov photons with high efficiency. More than 60,000 analog signals will be digitized and processed in the front end electronics and send to the unified experiment data acquisition system.
    The detector components have been successfully produced and are now being installed in the spectrometer. Tested before on the bench, they are currently being installed in the mechanical frame. Part of the detector have been commissioned and connected to the acquisition system to register the cosmic ray particles. The first preliminary results are in accordance with previous expectations.
    We expect an excellent performance of the device which will allow at least a 4s separation of pions from kaons in the experiment kinematic region from 0.5 GeV/c to 4 GeV/c. (C) 2017 Elsevier B.V. All rights reserved.

    For the Belle II spectrometer a proximity focusing RICH counter with an aerogel radiator (ARICH) will be employed as a PID system in the forward end-cap region of the spectrometer. The detector will provide about 4 sigma separation of pions and kaons up to momenta of 3.5 GeV/c, at the kinematic limits of the experiment. We present the up-to-date status of the ARICH simulation and reconstruction software, focusing on the recent improvements of the reconstruction algorithms and detector description in the Geant4 simulation. In addition, as a demonstration of detector readout software functionality we show the first cosmic ray Cherenkov rings observed in the ARICH.

    The proximity-focusing Aerogel Ring-Imaging Cherenkov detector (ARICH) has been designed to separate kaons from pions in the forward end-cap of the Belle II spectrometer. The detector will be placed in 1.5 T magnetic field and must have immunity to it. In ARICH R&D, we solve the problem with new equipment called Hybrid Avalanche Photo-Detector (HAPD) which developed by Hamamatsu Photonics. Recently the production of about 500 HAPDs was completed. We test HAPDs in magnetic field in KEK. We found some HAPDs have significant amount of dead time, which reaches up to 30% in the worst case. The dead time is caused by very large (more than 10,000 times larger than a single photon signal) and frequent (similar to 5 Hz) signals, which make electronics paralysed. The huge signals are observed in about 30% of HAPDs. To identify the origin and understand the mechanism, we perform some extra test of HAPDs. We find a strange dependence of the huge signals to the APD bias voltage. If we reduce the bias voltage applied to one of the 4 APDs by 10 V, the frequency of the huge signals is much reduced. On the other hand, if we reduce the voltage of all the 4 HAPDs, huge signals do not decrease, or even increase in some case. We also find the huge signals seems to be related to the vacuum inside HAPD. We present about the observation of the huge signals of HAPDs in the magnetic field, and our strategy to manage it.

    The Belle II detector is under construction at KEK in Japan. In the forward endcap region of the Belle II detector, particle identification (PID) is performed by the Aerogel Ring Imaging Cherenkov (ARICH) counter composed of aerogel tiles and 144-channel Hybrid Avalanche Photo-Detectors (HAPDs). The photon detection efficiency of the photosensor is important for a stable operation of the ARICH. To examine the performance of the HAPDs periodically, a monitor system using scattered photons injected by optical fibers is being developed. In this paper, we report the test using the prototype monitor system and the tests with a partially built ARICH detector.

    We have developed a RICH counter as a new forward particle identification device for the Belle II experiment. As a Cherenkov radiator in this counter, a dual aerogel layer combination consisting of two refractive indicies, n=1.045 and 1.055, is employed. Mass production of these aerogel tiles has been done during 2013-2014 with new method improved by Chiba group. Optical qualities for them have been examined. The refractive indices of the obtained tiles were found to be in good agreement with our expectations, and the transparencies were high enough to be used for the RICH radiator.

    A slow control system (SCS) for the Aerogel Ring Imaging Cherenkov (ARICH) counter in the Belle II experiment was newly developed and coded in the development frameworks of the Belle II DAQ software. The ARICH is based on 420 Hybrid Avalanche Photo-Detectors (HAPDs). Each HAPD has 144 pixels to be readout and requires 6 power supply (PS) channels, therefore a total number of 2520 PS channels and 60,480 pixels have to be configured and controlled. Graphical User Interfaces (GUIs) with detector oriented view and device oriented view, were also implemented to ease the detector operation. The ARICH SCS is in operation for detector construction and cosmic rays tests. The paper describes the detailed features of the SCS and preliminary results of operation of a reduced set of hardware which confirm the scalability to the full detector.

    We present a measurement of the Michel parameters of the $\tau$ lepton,<br />
    $\bar{\eta}$ and $\xi\kappa$, in the radiative leptonic decay $\tau^-<br />
    \rightarrow \ell^- \nu_{\tau} \bar{\nu}_{\ell} \gamma$ using<br />
    711~f$\mathrm{b}^{-1}$ of collision data collected with the Belle detector at<br />
    the KEKB $e^+e^-$ collider. The Michel parameters are measured in an unbinned<br />
    maximum likelihood fit to the kinematic distribution of<br />
    $e^+e^-\rightarrow\tau^+\tau^-\rightarrow (\pi^+\pi^0<br />
    \bar{\nu}_\tau)(\ell^-\nu_{\tau}\bar{\nu}_{\ell}\gamma)$ $(\ell=e$ or $\mu)$.<br />
    The measured values of the Michel parameters are $\bar{\eta} = -1.3 \pm 1.5 \pm<br />
    0.8$ and $\xi\kappa = 0.5 \pm 0.4 \pm 0.2$, where the first error is<br />
    statistical and the second is systematic. This is the first measurement of<br />
    these parameters. These results are consistent with the Standard Model<br />
    predictions within their uncertainties and constrain the coupling constants of<br />
    the generalized weak interaction.

    For the Belle II spectrometer a proximity focusing RICH counter with an aerogel radiator (ARICH) will be employed as a PID system in the forward endcap region of the spectrometer. The main challenge was the development of a reliable multichannel sensor for single photons that Operates in the high magnetic field of the spectrometer (1.5 T) and withstands the radiation levels expected at the experiment. A 144 channel Hybrid Avalanche Photo-Detector (HAPD) was developed with Hamamatsu Photonics K.K. and the mass production of similar to 480 HAPDs was completed recently. While our first tests of HAPD performance in the magnetic field (before mass production) showed no issues, we lately observed a presence of very large signal pulses (similar to 5000 x single photon signal), generated internally within about 20% of HAPDs, while operating in the magnetic field. The rate of these pulses varies from sample to sample. These pulses impact the HAPD performance in two ways: they introduce periods Of dead time and, in some cases, damage to the front-end electronics was observed. Here we present conditions under which such large pulses are generated, their properties and impact on HAPD performance, and discuss possible mechanism of their origin. (C) 2016 Elsevier B.V.

    © The Author(s) 2016. We have developed a new type of particle identification device, called an aerogel ring imaging Cherenkov (ARICH) counter, for the Belle II experiment. It uses silica aerogel tiles as Cherenkov radiators. For detection of Cherenkov photons, hybrid avalanche photo-detectors (HAPDs) are used. The designed HAPD has a high sensitivity to single photons under a strong magnetic field. We have confirmed that the HAPD provides high efficiency for single-photon detection even after exposure to neutron and γ -ray radiation that exceeds the levels expected in the 10-year Belle II operation. In order to confirm the basic performance of the ARICH counter system, we carried out a beam test at the using a prototype of the ARICH counter with six HAPD modules. The results are in agreement with our expectations and confirm the suitability of the ARICH counter for the Belle II experiment. Based on the in-beam performance of the device, we expect that the identification efficiency at 3.5GeV/c is 97.4% and 4.9% for pions and kaons, respectively. This paper summarizes the development of the HAPD for the ARICH and the evaluation of the performance of the prototype ARICH counter built with the final design components.

    We present an analysis of charm quark fragmentation at 10.6 GeV, based on a data sample of 103fb-1 collected by the Belle detector at the KEKB accelerator. We consider fragmentation into the main charmed hadron ground states, namely D0,D+,Ds+ and Λc+, 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 Υ(4S) resonance and measure the distribution of their production angle in e+e- annihilation events and in B decays. © 2006 The American Physical Society.
