Abstract: We report on the first observations of B�0?D1(2430)0?, B�0?D1(2420)0?, and B�0?D2?(2460)0? decays. The B�0?D?+?(1450)- decay is also observed. The branching fraction measurements are based on (771.6�10.6)�106 BB� events collected at the (4S) resonance with the Belle detector at the KEKB asymmetric-energy e+e- collider. The fractions of longitudinal polarization of the D?? states as well as partial wave fractions of the D1(2430)0 are obtained. We also set a 90% confidence level upper limit for the product of branching fractions of B(B�0?D?+b1(1235)-)�B(b1(1235)-???-). The measurements show evidence of nontrivial final-state interaction phases for the ?-meson-like amplitudes. � 2015 American Physical Society.

Abstract: We report a search for $B$ decays to selected final states with the $\eta_c$ meson: $B^{\pm}\to K^{\pm}\eta_c\pi^+\pi^-$, $B^{\pm}\to K^{\pm}\eta_c\omega$, $B^{\pm}\to K^{\pm}\eta_c\eta$ and $B^{\pm}\to K^{\pm}\eta_c\pi^0$. The analysis is based on $772\times 10^6$ $B\bar{B}$ pairs collected at the $\Upsilon(4S)$ resonance with the Belle detector at the KEKB asymmetric-energy $e^+e^-$ collider. We set 90\% confidence level upper limits on the branching fractions of the studied $B$ decay modes, independent of intermediate resonances, in the range $(0.6-5.3)\times 10^{-4}$. We also search for molecular-state candidates in the $D^0\bar{D}^{*0}-\bar{D}^0D^{*0}$, $D^0\bar{D}^0+\bar{D}^0D^0$ and $D^{*0}\bar{D}^{*0}+\bar{D}^{*0}D^{*0}$ combinations, neutral partners of the $Z(3900)^{\pm}$ and $Z(4020)^{\pm}$, and a poorly understood state $X(3915)$ as possible intermediate states in the decay chain, and set 90\% confidence level upper limits on the product of branching fractions to the mentioned intermediate states and decay branching fractions of these states in the range $(0.6-6.9)\times 10^{-5}$., Comment: 11 pages, 12 figures, accepted to JHEP

Abstract: We report a measurement of the differential cross section of $��^0$ pair production in single-tag two-photon collisions, $��^* ��\to ��^0 ��^0$, in $e^+ e^-$ scattering. The cross section is measured for $Q^2$ up to 30 GeV$^2$, where $Q^2$ is the negative of the invariant mass squared of the tagged photon, in the kinematic range 0.5 GeV < W < 2.1 GeV and $|\cos ��^*|$ < 1.0 for the total energy and pion scattering angle, respectively, in the $��^* ��$ center-of-mass system. The results are based on a data sample of 759 fb$^{-1}$ collected with the Belle detector at the KEKB asymmetric-energy $e^+ e^-$ collider. The transition form factor of the $f_0(980)$ and that of the $f_2(1270)$ with the helicity-0, -1, and -2 components separately are measured for the first time and are compared with theoretical calculations., 36 pages, 37 figures, 11 tables, Belle Preprint 2015-15, KEK Preprint 2015-24

Abstract: The process e+e-???cJ (J=1, 2) is studied via initial state radiation using 980fb-1 of data at and around the (nS) (n=1, 2, 3, 4, 5) resonances collected with the Belle detector at the KEKB asymmetric-energy e+e- collider. No significant signal is observed except from ?(2S) decays. Upper limits on the cross sections between s=3.80 and 5.56 GeV are determined at the 90% credibility level, which range from a few pb to a few tens of pb. We also set upper limits on the decay rate of the vector charmonium [?(4040), ?(4160), and ?(4415)] and charmoniumlike [Y(4260), Y(4360), and Y(4660)] states to ??cJ. � 2015 American Physical Society.

Abstract: We report the first observation of the decays $B^0 \rightarrow p\bar�� D^{(*)-}$. The data sample of $711$ fb$^{-1}$ used in this analysis corresponds to $772$ million $B\bar{B}$ pairs, collected at the $��(4S)$ resonance by the Belle detector at the KEKB asymmetric-energy $e^{+}e^{-}$ collider. We observe $19.8��$ and $10.8��$ excesses of events for the two decay modes and measure the branching fractions of $B^0 \rightarrow p\bar�� D^{-}$ and $B^0 \rightarrow p\bar�� D^{*-}$ to be $(25.1\pm2.6\pm3.5)\times10^{-6}$ and $(33.6\pm6.3\pm4.4)\times10^{-6}$, 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 di-baryon ($p\bar��$) system is observed, consistent with that observed in similar $B$ decays., 16 pages, 3 figures and 3 tables, submitted to PRL

Abstract: We report a measurement of the branching fraction ratios R(D(*)) of Bbar -> D(*) tau- nubar_tau relative to Bbar -> D()* l- nubar_l (where l = e or mu) using the full Belle data sample of 772 x 10^6 BBbar pairs collected at the Y(4S) resonance with the Belle detector at the KEKB asymmetric-energy e+e- collider. The measured values are R(D)= 0.375 +- 0.064(stat.) +- 0.026(syst.) and R(D*) = 0.293 +- 0.038(stat.) +- 0.015(syst.). The analysis uses hadronic reconstruction of the tag-side B meson and purely leptonic tau decays. The results are consistent with earlier measurements and do not show a significant deviation from the standard model prediction., Accepted for publication in Phys.Rev.D

Abstract: We report inclusive and exclusive measurements for $��_{c1}$ and $��_{c2}$ production in $B$ decays. We measure $\mathcal{B}(B \to ��_{c1} X)$= $(3.03 \pm 0.05(\mbox{stat}) \pm 0.24(\mbox{syst})) \times 10^{-3}$ and $\mathcal{B}(B \to ��_{c2} X)$= $(0.70 \pm 0.06(\mbox{stat}) \pm 0.10(\mbox{syst})) \times 10^{-3}$. For the first time, $��_{c2}$ production in exclusive $B$ decays in the modes $B^0 \to ��_{c2}��^- K^+$ and $B^+ \to ��_{c2} ��^+ ��^- K^+$ has been observed, along with first evidence for the $B^+ \to ��_{c2} ��^+ K_S^0$ decay mode. For $��_{c1}$ production, we report the first observation in the $B^+ \to ��_{c1} ��^+ ��^- K^+$, $B^0 \to ��_{c1} ��^+ ��^- K_S^0$ and $B^0 \to ��_{c1} ��^0 ��^- K^+$ decay modes. Using these decay modes, we observe a difference in the production mechanism of $��_{c2}$ in comparison to $��_{c1}$ in $B$ decays. In addition, we report searches for $X(3872)$ and $��_{c1}(2P)$ in the $B^+ \to (��_{c1} ��^+ ��^-) K^+$ decay mode. The reported results use $772 \times 10^{6}$ $B\overline{B}$ events collected at the $��(4S)$ resonance with the Belle detector at the KEKB asymmetric-energy $e^+e^-$ collider., 14 Pages, 8 Figures,4 Tables; Published in PRD 93, 052016 (2016)

Abstract: We use 772�106 BB� meson pairs collected at the ?(4S) resonance with the Belle detector to measure the branching fraction for B�?Xs?. Our measurement uses a sum-of-exclusives approach in which 38 of the hadronic final states with strangeness equal to +1, denoted by Xs, are reconstructed. The inclusive branching fraction for MXs

Abstract: We report a measurement of the time-dependent CP asymmetry of B[over ¯]^{0}→D_{CP}^{(*)}h^{0} decays, where the light neutral hadron h^{0} is a π^{0}, η, or ω meson, and the neutral D meson is reconstructed in the CP eigenstates K^{+}K^{-}, K_{S}^{0}π^{0}, or K_{S}^{0}ω. The measurement is performed combining the final data samples collected at the ϒ(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)×10^{6} BB[over ¯] pairs recorded by the BABAR detector and (772±11)×10^{6} BB[over ¯] pairs recorded by the Belle detector. We measure the CP asymmetry parameters -η_{f}S=+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 ¯]^{0}→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.

In addition, we report negative results from a search for hypothesized neutral (z0) and doubly charged (z++) isospin partners of the Ds0?+(2317) and provide upper limits on the product branching fractions B(B0?D0z0)�B(z0?Ds+?-) and B(B+?D0z++)�B(z++?Ds+?+) that are more than an order of magnitude smaller than theoretical expectations for the hypotheses that the Ds0?+(2317) is a member of an isospin triplet.

Abstract: We present a determination of the magnitude of the Cabibbo-Kobayashi-Maskawa matrix element $|V_{cb}|$ using the decay $B\to D\ell��_\ell$ ($\ell=e,��$) based on 711 fb$^{-1}$ of $e^+e^-\to ��(4S)$ data recorded by the Belle detector and containing $772 \times 10^6$ $B\bar{B}$ pairs. One $B$ meson in the event is fully reconstructed in a hadronic decay mode while the other, on the signal side, is partially reconstructed from a charged lepton and either a $D^+$ or $D^0$ meson in a total of 23 hadronic decay modes. The isospin-averaged branching fraction of the decay $B\to D\ell��_\ell$ is found to be $\mathcal{B}(B^0 \to D^- \ell^+ ��_{\ell})=(2.31\pm 0.03(\mathrm{stat})\pm 0.11(\mathrm{syst}))\%$. Analyzing the differential decay rate as a function of the hadronic recoil with the parameterization of Caprini, Lelouch and Neubert and using the form-factor prediction $\mathcal{G}(1)=1.0541\pm 0.0083$ calculated by FNAL/MILC, we obtain $��_\mathrm{EW}|V_{cb}|=(40.12\pm 1.34)\times 10^{-3}$, where $��_\mathrm{EW}$ is the electroweak correction factor. Alternatively, assuming the model-independent form-factor parameterization of Boyd, Grinstein and Lebed and using lattice QCD data from the FNAL/MILC and HPQCD collaborations, we find $��_\mathrm{EW}|V_{cb}|=(41.10 \pm 1.14)\times 10^{-3}$., 17 pages, 8 figures and 8 tables, submitted to PRD; changes to previous version: updated affiliations, moved introduction of z, added Vcb result without electroweak correction factor

Abstract: We report on the first observations of $\bar{B}^0 \to D_1(2430)^0 ��$, $\bar{B}^0 \to D_1(2420)^0 ��$ and $\bar{B}^0 \to D^*_2(2460)^0 ��$ decays. The $\bar{B}^0 \to D^{*+} ��(1450)^-$ decay is also observed. The branching fraction measurements are based on $(771.6 \pm 10.6)\times 10^6$ $B\bar{B}$ events collected at the $��(4S)$ resonance with the Belle detector at the KEKB asymmetric-energy $e^+e^-$ collider. The fractions of longitudinal polarization of the $D^{**}$ states as well as partial wave fractions of the $D_1(2430)^0$ are obtained. We also set a $90\%$ confidence level upper limit for the product of branching fractions of $\mathcal{B}(\bar{B}^0 \to D^{*+} b_1(1235)^-) \times \mathcal{B}(b_1(1235)^- \to ��^-)$. The measurements show evidence of nontrivial final-state interaction phases for the $��$-like amplitudes., 29 pages, 12 figures, submitted to Physical Review D

Abstract: We present a search for the rare leptonic decays B+?e+?e and B+??+??, using the full (4S) data sample of 772�106 BB� pairs collected with the Belle detector at the KEKB asymmetric-energy e+e- collider. One of the B mesons from the (4S)?BB� 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 B(B+?e+?e)

Abstract: We report a search for charmless hadronic decays of neutral $B$ mesons to $��' K^{*}(892)^{0}$. The results are based on a 711fb$^{-1}$ data sample that contains $772\times 10^6 B\overline{B}$ pairs, collected at the $��(4S)$ resonance with the Belle detector at the KEKB asymmetric energy $e^+e^-$ collider. We observe the decay for the first time with a significance of 5.0 standard deviations and obtain its branching fraction ${\cal B}[B^0\to��' K^{*}(892)^{0}]=[2.6\pm0.7{\rm (stat)}\pm0.2{\rm (syst)}]\times 10^{-6}$. We also measure the $CP$ violating asymmetry as ${\cal A}_{CP}[B^0\to��' K^{*}(892)^{0}]=-0.22\pm0.29{\rm (stat)}\pm0.07{\rm syst}$., 11 pages, 2 figures, submitted PRD(RC)

Abstract: We report measurement of the cross section of $e^+e^-\to ��^+��^-��(2S)$ between 4.0 and $5.5 {\rm GeV}$, based on an analysis of initial state radiation events in a $980 \rm fb^{-1}$ data sample recorded with the Belle detector. The properties of the $Y(4360)$ and $Y(4660)$ states are determined. Fitting the mass spectrum of $��^+��^-��(2S)$ with two coherent Breit-Wigner functions, we find two solutions with identical mass and width but different couplings to electron-positron pairs: $M_{Y(4360)} = (4347\pm 6\pm 3) {\rm MeV}/c^2$, $��_{Y(4360)} = (103\pm 9\pm 5) {\rm MeV}$, $M_{Y(4660)} = (4652\pm10\pm 8) {\rm MeV}/c^2$, $��_{Y(4660)} = (68\pm 11\pm 1) \rm MeV$; and ${\cal{B}}[Y(4360)\to ��^+��^-��(2S)]\cdot ��_{Y(4360)}^{e^+e^-} = (10.9\pm 0.6\pm 0.7) \rm eV$ and ${\cal{B}}[Y(4660)\to ��^+��^-��(2S)]\cdot ��_{Y(4660)}^{e^+e^-} = (8.1\pm 1.1\pm 0.5) \rm eV$ for one solution; or ${\cal{B}}[Y(4360)\to ��^+��^-��(2S)]\cdot ��_{Y(4360)}^{e^+e^-} = (9.2\pm 0.6\pm 0.6) \rm eV$ and ${\cal{B}}[Y(4660)\to ��^+��^-��(2S)]\cdot ��_{Y(4660)}^{e^+e^-} = (2.0\pm 0.3\pm 0.2) \rm eV$ for the other. Here, the first errors are statistical and the second systematic. Evidence for a charged charmoniumlike structure at $4.05 {\rm GeV}/c^2$ is observed in the $��^{\pm}��(2S)$ intermediate state in the $Y(4360)$ decays., 21 pages, 12 figures

Abstract: We report a measurement of D0-D?0 mixing parameters and a search for indirect CP violation through a time-dependent amplitude analysis of D0?KS0?+?- decays. The results are based on 921fb-1 of data accumulated with the Belle detector at the KEKB asymmetric-energy e+e- collider. Assuming CP conservation, we measure the mixing parameters x=(0.56�0.19- 0.09-0.09+0.03+0.06)% and y=(0.30�0.15-0.05-0.06+0.04+0.03)%, where the errors are statistical, experimental systematic, and systematic due to the amplitude model, respectively. With CP violation allowed, the parameters |q/p|=0.90-0.15-0.04-0.05+0.16+0.05+0.06 and arg(q/p)=(-6�11�3- 4+3)� are found to be consistent with conservation of CP symmetry in mixing and in the interference between mixing and decay, respectively. � 2014 American Physical Society.

Abstract: We present a measurement of the branching fractions and charge-parity-(CP-)violating parameters in B??K decays. The results are obtained from the final data sample containing 772�106 BB? pairs collected at the ?(4S) resonance with the Belle detector at the KEKB asymmetric-energy e+e- collider. We obtain the branching fractions B(B0??K0)=(4.5�0.4(stat)�0.3(syst))�10-6, B(B+??K+)=(6.8�0.4(stat)�0.4(syst))�10-6 which are in agreement with their respective current world averages. For the CP-violating parameters, we obtain A?KS0=-0.36�0.19(stat)�0. 05(syst),S?KS0=+0.91�0.32(stat)�0.05(syst),A?K+=-0. 03�0.04(stat)�0.01(syst), where A and S represent the direct and mixing-induced CP asymmetry, respectively. We find no evidence of CP violation in the decay channel B+??K+; however, we obtain the first evidence of CP violation in the B0??KS0 decay channel at the level of 3.1 standard deviations. � 2014 American Physical Society.

Abstract: We present the results of an amplitude analysis of anti-B0 -> J/psi K- pi+ decays. A new charged charmoniumlike state Zc(4200)+ decaying to J/psi pi+ is observed with a significance of 6.2 sigma. The mass and width of the Zc(4200)+ are 4196 +31-29 +17-13 MeV/c^2 and 370 +70-70 +70-132 MeV, respectively; the preferred assignment of the quantum numbers is J^P = 1^+. In addition, we find evidence for Zc(4430)+ -> J/psi pi+. The analysis is based on a 711 fb^-1 data sample collected by the Belle detector at the asymmetric-energy e+ e- collider KEKB., 14 pages, 13 figures

Abstract: We report measurements of branching fractions of ? lepton decays to final states with a KS0 meson using a 669fb-1 data sample accumulated with the Belle detector at the KEKB asymmetric-energy e+e- collider. The inclusive branching fraction is measured to be B(?-?KS0X-??)=(9. 15�0.01�0.15)�10-3, where X- can be anything; the exclusive branching fractions are B(?-??-KS0??)=(4.16�0. 01�0.08)�10-3, B(?-?K-KS0??)=(7.40�0. 07�0.27)�10-4, B(?-??-KS0?0??)=(1. 93�0.02�0.07)�10-3, B(?-?K-KS0?0??)=(7. 48�0.10�0.37)�10-4, B(?-??-KS0KS0??)=(2. 33�0.03�0.09)�10-4, B(?-??-KS0KS0?0??) =(2.00�0.22�0.20)�10-5, where the first uncertainty is statistical and the second is systematic. For each mode, the accuracy is improved over that of pre-B-factory measurements by a factor ranging from five to ten. In ?-??-KS0KS0?0?? decays, clear signals for the intermediate states ?-??-f1(1285)?? and ?-?K*- KS0?0?? are observed. � 2014 American Physical Society.

Abstract: Using data samples of 102�106 (1S) and 158�106 (2S) events collected with the Belle detector, a first experimental search has been made for double-charmonium production in the exclusive decays (1S,2S)?J/?(??)+X, where X=?c, ?cJ(J=0,1,2), ?c(2S), X(3940), and X(4160). No significant signal is observed in the spectra of the mass recoiling against the reconstructed J/? or ?? except for the evidence of ?c1 production with a significance of 4.6? for (1S)?J/?+?c1. The measured branching fraction B((1S)?J/?+?c1) is [3.90�1.21(stat)�0.23(syst)]�10-6. The 90% C.L. upper limits on the branching fractions of the other modes having a significance of less than 3? are determined. These results are consistent with theoretical calculations using the nonrelativistic QCD factorization approach. � 2014 American Physical Society.

Abstract: We report a measurement of ${D^{0}}$-${\overline{D}{}^{0}}$ mixing parameters and a search for indirect $CP$ violation through a time-dependent amplitude analysis of ${D^0\to K_S^0��^+��^-}$ decays. The results are based on 921~fb$^{-1}$ of data accumulated with the Belle detector at the KEKB asymmetric-energy $e^+e^-$ collider. Assuming $CP$ conservation, we measure the mixing parameters $x=(0.56\pm0.19^{+0.03}_{-0.09}{^{+0.06}_{-0.09}})\%$ and $y=(0.30\pm0.15^{+0.04}_{-0.05}{^{+0.03}_{-0.06})}\%$, where the errors are statistical, experimental systematic, and systematic due to the amplitude model, respectively. With $CP$ violation allowed, the parameters $|q/p|=0.90^{+0.16}_{-0.15}{^{+0.05}_{-0.04}}{^{+0.06}_{-0.05}}$ and $\arg(q/p)=(-6\pm11{\pm3}{^{+3}_{-4}})^{\circ}$ are found to be consistent with conservation of $CP$ symmetry in mixing and in the interference between mixing and decay, respectively., submitted to PRD(RC)

Abstract: We present a measurement of the time-dependent $CP$ violation parameters in $B^0\to��'K^0$ decays. The measurement is based on the full data sample containing $772\times 10^6$ $B\bar{B}$ pairs collected at the $��(4S)$ resonance using the Belle detector at the KEKB asymmetric-energy $e^+e^-$ collider. The measured values of the mixing-induced and direct $CP$ violation parameters are: \begin{align} \sin 2 ��^{\rm eff}_1 &= +0.68\pm 0.07 \pm 0.03, \nonumber \\ \mathcal{A}_{��'K^0} &= +0.03\pm 0.05\pm 0.04, \nonumber \end{align} where the first uncertainty is statistical and the second is systematic. The values obtained are the most accurate to date. Furthermore, these results are consistent with our previous measurements and with the world-average value of $\sin 2��_1$ measured in $B^0\to J/��K^0$ decays.}, 15 pages, 3 figures

Abstract: We search for the decay $B_{s}^{0}\rightarrow��$ and measure the branching fraction for $B_{s}^{0}\rightarrow��$ using 121.4~$\textrm{fb}^{-1}$ of data collected at the $��(\mathrm{5}S)$ resonance with the Belle detector at the KEKB asymmetric-energy $e^{+}e^{-}$ collider. The $B_{s}^{0}\rightarrow��$ branching fraction is measured to be $(3.6 \pm 0.5 (\mathrm{stat.}) \pm 0.3 (\mathrm{syst.}) \pm 0.6 (f_{s})) \times 10^{-5}$, where $f_{s}$ is the fraction of $B_{s}^{(*)}\bar{B}_{s}^{(*)}$ in $b\bar{b}$ 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 $B_{s}^{0}\rightarrow��$ and set a $90\%$ confidence-level upper limit on its branching fraction at $ 3.1 \times 10^{-6}$. This constitutes a significant improvement over the previous result., 6 pages, 3 figures

Abstract: The $e^+e^- \to ��^+ ��^- ��^0 ��_{bJ}$ ($J=0,~1,~2$) processes are studied using a 118~fb$^{-1}$ data sample collected at a center-of-mass energy of 10.867 GeV, in the $��(10860)$ energy range, with the Belle detector. The $��^+ ��^- ��^0 ��_{b1}$, $��^+��^-��^0��_{b2}$, $��_{b1}$ signals and the evidence of $��_{b2}$ are observed for the first time and the cross sections are measured. No significant $��^+��^-��^0��_{b0}$ or $��_{b0}$ signal is observed and 90\% confidence level upper limits on the cross sections for these two processes are obtained. In the $��^+��^-��^0$ invariant mass spectrum, significant non-$��$ signals are also observed. We search for the $X(3872)$-like state with a hidden $b\bar{b}$ component (named $X_b$) decaying into $��(1S)$; no significant signal is observed with a mass between $10.55$ and $10.65$ GeV/$c^2$., 7 pages, 3 figures, accepted for publication as a Letter in Physical Review Letters

Abstract: We present a study of the branching fraction of the decay B0??0?0 and the fraction of longitudinally polarized ?0 mesons in this decay. The results are obtained from the final data sample containing 772�106 BB? pairs collected at the (4S) resonance with the Belle detector at the KEKB asymmetric-energy e+e- collider. We find 166�59 B0??0?0 events (including systematic uncertainties), corresponding to a branching fraction of B(B0??0?0)=(1.02�0.30(stat) �0.15(syst))�10-6 with a significance of 3.4 standard deviations and a longitudinal polarization fraction fL=0.21-0.22+0.18(stat)�0. 15(syst). We use the longitudinal polarization fraction to determine the Cabibbo-Kobayashi-Maskawa matrix angle ?2=(84.9�13.5)� through an isospin analysis in the B??? system. We furthermore find 125�41 B0?f0?0 events, corresponding to B(B0?f0?0) �B(f0??+?-)=(0.78�0.22(stat)�0.11(syst)) �10-6, with a significance of 3.1 standard deviations.

Abstract: We search for CP violation in neutral charm meson decays using a data sample with an integrated luminosity of 966 fb^-1 collected with the Belle detector at the KEKB e+e- asymmetric-energy collider. The asymmetry obtained in the rate of D^0 and D^0-bar decays to the pi^0 pi^0 final state, [-0.03+-0.64(stat)+-0.10(syst)]%, is consistent with no CP violation. This constitutes an order of magnitude improvement over the existing result. We also present an updated measurement of the CP asymmetry in the D^0 -> K_S pi^0 decay: A_{CP}(D^0 -> K_S pi^0) = [-0.21+-0.16(stat)+-0.07(syst)]%.

Abstract: We search for the charmless B0 decay with final state particles p???-? using the full data sample that contains 772�106BB? pairs collected at the ?(4S) resonance with the Belle detector at the KEKB asymmetric-energy e+e- collider. This decay is predicted to proceed predominantly via the b?s? radiative penguin process with a high energy photon. No significant signal is found. We set an upper limit of 6.5�10-7 for the branching fraction of B0?p???-? at the 90% confidence level. � 2014 American Physical Society.

Abstract: The e+e-??+?-?0?bJ (J=0,1,2) processes are studied using a 118fb-1 data sample acquired with the Belle detector at a center-of-mass energy of 10.867 GeV. Unambiguous ?+?-?0?bJ (J=1,2), ??b1 signals are observed, and indication for ??b2 is seen, both for the first time, and the corresponding cross section measurements are presented. No significant ?+?-?0?b0 or ??b0 signals are observed, and 90% confidence level upper limits on the cross sections for these two processes are obtained. In the ?+?-?0 invariant mass spectrum, significant non-? signals are also observed. We search for the X(3872)-like state (named Xb) decaying into ??(1S); no significant signal is observed with a mass between 10.55 and 10.65GeV/c2. � 2014 American Physical Society.

Abstract: We report a measurement of the $B^0$ and $B^+$ meson decays to the $D_s^-K^0_S ��^+$ and $D_s^- K^+K^+$ final states, respectively, using $657 \times 10^{6} B\overline{B}$ pairs collected at the $��(4S)$ resonance with the Belle detector at the KEKB asymmetric-energy $e^+e^-$ collider. Using the $D_s^-\to ��^-$, $K^{*}(892)^0 K^-$ and $K^0_S K^-$ decay modes for the $D_s$ reconstruction, we measure the following branching fractions: ${\cal B}(B^0\to D_s^{-}K^0_S��^+)=[0.47 \pm 0.06 (\mathrm {stat}) \pm 0.05 (\mathrm {syst})]\times 10^{-4}$ and ${\cal B}(B^+\to D_s^-K^+K^+)= [0.93 \pm 0.22 (\mathrm {stat})\pm 0.10 (\mathrm {syst})]\times 10^{-5}$. We find the ratio of the branching fraction of $B^+\to D_s^-K^+K^+$ to that of the analogous Cabibbo favored $B^+\to D_s^-K^+��^+$ decay to be ${\cal R}_{\cal B} = 0.054 \pm 0.013 ({\rm stat}) \pm 0.006 ({\rm syst})$, which is consistent with the na\"��ve factorization model. We also observe a deviation from the three-body phase-space model for both studied decays., 13 pages, 4 figures, submitted to PRD

Abstract: We report a measurement of the branching fraction of $B^+ \to ��^+ ��_��$ decays using a data sample of $772 \times 10^6 B \bar{B}$ pairs, collected at the $��(4S)$ resonance with the Belle detector at the KEKB asymmetric-energy $e^+e^-$ collider. We reconstruct the accompanying $B$ meson in a semileptonic decay and detect the $B^+ \to ��^+ ��_��$ candidate in the recoiling event. We obtain a branching fraction of ${\cal B}(B^+ \to ��^+ ��_��) = [1.25 \pm 0.28 ({\rm stat.}) \pm 0.27({\rm syst.})] \times 10^{-4}$. This result is in good agreement with previous measurements and the expectation from calculations based on the Standard Model., Belle conference paper for the International Workshop on the CKM Unitarity Triangle (CKM 2014)
