Abstract: The Pohang-Accelerator-Laboratory X-ray free-electron laser (PAL-XFEL) emits intense, ultra-short X-ray pulses, enabling studies on ultra-small and -fast dynamics in various fields. We designed and fabricated silicon p-intrinsic-n photo-diodes (PDs) to detect strong X-ray pulses. Four types of PDs were fabricated with different metal shapes on the P- and N-sides. The fabrication process was split into two parts, based on the thickness of the Al metal and anti- reflective coating (ARC) layers, to evaluate the fabrication process feasibility and the detection performance. A beam test was performed with X-ray pulses at the soft X-ray beamline of the PAL-XFEL using the proposed PDs and a commercial PD. The test was designed to evaluate the effects of the metal and ARC layers and compare the detection efficiency depending on the X-ray entrance side and signal readout side. The waveforms were saved during the test and integrated to obtain the charges. Thereafter, they were analyzed and normalized, and compared. This paper presents the preparation, setup, and procedure of the beam test, and the test results are described. [ABSTRACT FROM AUTHOR]

Abstract: When testing and calibrating particle detectors in a test beam, accurate tracking information independent of the detector being tested is extremely useful during the offline analysis of the data. A general-purpose Silicon Beam Tracker (SBT) was constructed with an active area of 32.0 x 32.0 mm2 to provide this capability for the beam calibration of the Cosmic Ray Energetics And Mass (CREAM) calorimeter. The tracker consists of two modules, each comprised of two orthogonal layers of 380 {\mu}m thick silicon strip sensors. In one module each layer is a 64-channel AC-coupled single-sided silicon strip detector (SSD) with a 0.5 mm pitch. In the other, each layer is a 32-channel DC-coupled single-sided SSD with a 1.0 mm pitch. The signals from the 4 layers are read out using modified CREAM hodoscope front-end electronics with a USB 2.0 interface board to a Linux DAQ PC. In this paper, we present the construction of the SBT, along with its performance in radioactive source tests and in a CERN beam test in October 2006., Comment: 4 pages, 10 figures, 1 table, SORMA WEST 2008 poster #204

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

Abstract: Physical review letters 118(5), 051801(2017). doi:10.1103/PhysRevLett.118.051801, We report the first observation of the radiative charm decay $D^{0}→ρ^{0}γ$ and the first search for CP violation in decays $D^{0}→ρ^{0}γ$, ϕγ, and $\bar{K}$*0(892)γ, using a data sample of 943 fb$^{−1}$ collected with the Belle detector at the KEKB asymmetric-energy $e^{+}e^−$ collider. The branching fraction is measured to be B($D^{0}→ρ^{0}γ$)=(1.77±0.30±0.07)×10$^{−5}$, where the first uncertainty is statistical and the second is systematic. The obtained CP asymmetries A$_{CP}$($D^{0}→ρ^{0}γ$)=+0.056±0.152±0.006, A$_{CP}$($D^{0}→ρ^{0}γ$) =− 0.094±0.066±0.001, and A$_{CP}$($D^{0}→\bar{K}*^{0}$γ)=−0.003±0.020±0.000 are consistent with no CP violation. We also present an improved measurement of the branching fractions B($D^{0}→ρ^{0}γ$)=(2.76±0.19±0.10)×10$^{−5}$ and B($D^{0}→\bar{K}*^{0}$γ)=(4.66±0.21±0.21)×10$^{−4}$., Published by American Physical Society, College Park, Md.

Abstract: We present the first measurement of the Michel parameters $\bar{\eta}$ and $\xi\kappa$ in the radiative leptonic decay of the $\tau$ lepton using 703 f$\mathrm{b}^{-1}$ of data collected with the Belle detector at the KEKB $e^+e^-$ collider. The Michel parameters are measured by an unbinned maximum likelihood fit to the kinematic information of $e^+e^-\rightarrow\tau^+\tau^-\rightarrow (\pi^+\pi^0 \bar{\nu})(l^-\nu\bar{\nu}\gamma)$ $(l=e$ or $\mu)$. The preliminary values of the measured Michel parameters are $\bar{\eta} = -2.0 \pm 1.5 \pm 0.8$ and $\xi\kappa = 0.6 \pm 0.4 \pm 0.2$, where the first error is statistical and the second is systematic. We present the first measurement of the Michel parameters η‾ and ξκ in the radiative leptonic decay of the τ lepton using 703 fb -1 of data collected with the Belle detector at the KEKB e+e− collider. The Michel parameters are measured by an unbinned maximum likelihood fit to the kinematic information of e+e−→τ+τ−→(π+π0ν‾)(l−νν‾γ)(l=e or μ) . The preliminary values of the measured Michel parameters are η‾=−2.0±1.5±0.8 and ξκ=0.6±0.4±0.2 , where the first error is statistical and the second is systematic.

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

Abstract: We report new measurements of the total cross sections for e+e-→ϒ(nS)π+π- (n=1, 2, 3) and e+e-→bb¯ from a high-luminosity fine scan of the region s=10.63–11.05 GeV with the Belle detector. We observe that the ϒ(nS)π+π- spectra have little or no nonresonant component and extract from them the masses and widths of ϒ(10860) and ϒ(11020) and their relative phase. We find M10860=(10891.1±3.2-1.7+0.6) MeV/c2 and Γ10860=(53.7-5.6 -5.4+7.1 +1.3) MeV and report first measurements M11020=(10987.5-2.5 -2.1+6.4 +9.0) MeV/c2, Γ11020=(61-19 -20+9 +2) MeV, and ϕ11020-ϕ10860=(-1.0±0.4-0.1+1.4) rad.

Abstract: Using data collected with the Belle detector at the KEKB asymmetric-energy $e^+e^-$ collider, we measure the energy dependence of the $e^+e^- \to h_b(nP)\pi^+\pi^-$ $(n=1,2)$ cross sections from thresholds up to $11.02\,$GeV. We find clear $\Upsilon(10860)$ and $\Upsilon(11020)$ peaks with little or no continuum contribution. We study the resonant substructure of the $\Upsilon(11020) \to h_b(nP)\pi^+\pi^-$ transitions and find evidence that they proceed entirely via the intermediate isovector states $Z_b(10610)$ and $Z_b(10650)$. The relative fraction of these states is loosely constrained by the current data: the hypothesis that only $Z_b(10610)$ is produced is excluded at the level of 3.3 standard deviations, while the hypothesis that only $Z_b(10650)$ is produced is not excluded at a significant level., Comment: 8 pages, 4 figures, submitted to Physical Review Letters

Abstract: We report a search for the charmless hadronic decay $B^0\to\eta \pi^0$ with a data sample corresponding to an integrated luminosity of 694 $\rm fb^{-1}$ containing $753\times10^6$ $B\bar{B}$ pairs. The data were collected by the Belle experiment running on the $\Upsilon(4S)$ resonance at the KEKB $e^+e^-$ collider. We measure a branching fraction $\mathcal{B}(B^0\to\eta\pi^0)=(4.1^{+1.7+0.5}_{-1.5-0.7})\times 10^{-7}$, where the first uncertainty is statistical and the second is systematic. Our measurement gives an upper limit of $\mathcal{B}(B^0\to\eta\pi^0), Comment: 11 pages, 3 figures, 2 tables, submitted to Physical Review D(R)

Abstract: We report new measurements of the total cross sections for $e^+e^-\to \Upsilon(n{\rm S})\pi^+\pi^-$ ($n$ = 1, 2, 3) and $e^+e^-\to b\bar b$ from a high-luminosity fine scan of the region $\sqrt{s} = 10.63$-$11.05$ GeV with the Belle detector. We observe that the $\Upsilon(n{\rm S})\pi^+\pi^-$ spectra have little or no non-resonant component and extract from them the masses and widths of $\Upsilon(10860)$ and $\Upsilon(11020)$ and their relative phase. We find $M_{10860}=(10891.1\pm3.2^{+0.6}_{-1.7})$ MeV/$c^2$ and $\Gamma_{10860}=(53.7^{+7.1}_{-5.6}\,^{+1.3}_{-5.4})$ MeV and report first measurements $M_{11020}=(10987.5^{+6.4}_{-2.5}\,^{+9.0}_{-2.1})$ MeV/$c^2$, $\Gamma_{11020}=(61^{+9}_{-19}\,^{+2}_{-20})$ MeV, and $\phi_{\rm 11020}-\phi_{\rm 10860} = (-1.0\pm0.4\,^{+1.4}_{-0.1})$ rad., Comment: University of Cincinnati preprint UCHEP-15-01, submitted to Physical Review D - Rapid Communications

Abstract: We report results on studies of the e+e− annihilation into three-body ϒ(nS)π+π− (n=1,2,3) final states including measurements of cross sections and the full amplitude analysis. The cross sections measured at s=10.866 GeV and corrected for the initial state radiation are σ(e+e−→ϒ(1S)π+π−)=(2.27±0.12±0.14) pb, σ(e+e−→ϒ(2S)π+π−)=(4.07±0.16±0.45) pb, and σ(e+e−→ϒ(3S)π+π−)=(1.46±0.09±0.16) pb. Amplitude analysis of the three-body ϒ(nS)π+π− final states strongly favors IG(JP)=1+(1+) quantum-number assignments for the two bottomonium-like Zb± states, recently observed in the ϒ(nS)π± and hb(mP)π± (m=1,2) decay channels. The results are obtained with a 121.4 fb−1 data sample collected with the Belle detector at the KEKB asymmetric-energy e+e− collider.

Abstract: We report new measurements of $R_{\Upsilon\pi\pi}\equiv\sigma(e^+e^-\to \Upsilon(n{\rm S})\pi^+\pi^-)/\sigma^0_{\mu\mu}$ ($n$ = 1, 2, 3) and $R_b\equiv\sigma(e^+e^-\to b\bar b)/\sigma^0_{\mu\mu}$ (where $\sigma^0_{\mu\mu}$ is the muon-pair Born cross section) in the region $\sqrt{s} = 10.63$-$11.05$ GeV, based on data collected with the Belle detector. Distributions in $R_{\Upsilon\pi\pi}$ and $R_b$ are fit for the masses and widths of the $\Upsilon(10860)$ and $\Upsilon(11020)$ resonances. Unlike $R_b$, which includes a large non-resonant $b\bar{b}$ component, we find that $R_{\Upsilon\pi\pi}$ is dominated by the two resonances. With $R_{\Upsilon\pi\pi}$ as the basis, the total rate at the $\Upsilon(10860)$ peak for known final states containing bottomonium(-like) resonances is estimated. We find that $\Upsilon(10860)$ is essentially saturated by such modes, raising doubts about the validity of masses measured using $R_b$. With $R_{\Upsilon\pi\pi}$, we measure $M_{10860}=(10891.1\pm3.2^{+0.6}_{-1.5})$ MeV/$c^2$ and $\Gamma_{10860}=(53.7^{+7.1}_{-5.6}\,^{+0.9}_{-5.4})$ MeV and report first measurements $M_{11020}=(10987.5^{+6.4}_{-2.5}\,^{+9.0}_{-2.1})$ MeV/$c^2$, $\Gamma_{11020}=(61^{+9}_{-19}\,^{+2}_{-20})$ MeV, and the relative phase $\phi_{\rm 11020}-\phi_{\rm 10860} = (-1.0\pm0.4\,^{+1.0}_{-0.1})$ rad.

Abstract: We report a search for the charmless hadronic decay B0 -> \eta \pi^0 with a data sample corresponding to an integrated luminosity of 694 fb^{-1} containing 753\times 10^6 B\bar{B} pairs. The data were collected by the Belle experiment running on the \Upsilon(4S) resonance at the KEKB e^+e^- collider. We measure a branching fraction \mathcal{B}(B^0\to\eta\pi^0)=(4.1^{+1.7+0.5}_{-1.5-0.7})\times 10^{-7}, where the first uncertainty is statistical and the second is systematic. Our measurement gives an upper limit of \mathcal{B}(B^0\to\eta\pi^0)

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., Comment: 14 pages, 13 figures

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 ${D^0\to K_S^0\pi^+\pi^-}$ 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., Comment: submitted to PRD(RC)

Abstract: We report results on studies of the e+e- annihilation into three-body Y(nS)pi+pi- (n=1,2,3) final states including measurements of cross sections and the full amplitude analysis. The cross sections measured at sqrt(s)=10.865 GeV and corrected for the initial state radiation are sigma(e+e-=>Y(1S)pi+pi-)=(2.27+-0.12+-0.14) pb, sigma(e+e-=>Y(2S)pi+pi-)=(4.07+-0.16+-0.45) pb, and sigma(e+e-=>Y(3S)pi+pi-)=(1.46+-0.09+-0.16) pb. Amplitude analysis of the three-body Y(nS)pi+pi- final states strongly favors I^G(J^P)=1^+(1^+) quantum-number assignments for the two bottomonium-like Zb+- states, recently observed in the Y(nS)pi+- and hb(mP)pi+- (m=1,2) decay channels. The results are obtained with a $121.4 1/fb data sample collected with the Belle detector at the KEKB asymmetric-energy e+e- collider., Comment: 15 pages, 6 tables, 9 figures.

Abstract: The cross sections of the processes $e^+ e^- \to K^+ K^- J/\psi$ and $K_S^0K_S^0J/\psi$ are measured via initial state radiation at center-of-mass energies between the threshold and 6.0~GeV using a data sample of 980~fb$^{-1}$ collected with the Belle detector on or near the $\Upsilon(nS)$ resonances, where $n=$1, 2, ..., 5. The cross sections for $e^+ e^- \to K^+ K^- J/\psi$ are at a few pb level and the average cross section for $e^+ e^- \to K_S^0K_S^0J/\psi$ is $1.8\pm 0.6 (\rm stat.)\pm 0.3 (\rm syst.)$~pb between 4.4 and 5.2~GeV. All of them are consistent with previously published results with improved precision. A search for resonant structures and associated intermediate states in the cross section of the process $e^+ e^- \to K^+ K^- J/\psi$ is performed., Comment: 14 pages, 7 figures

Abstract: We observe $D^0-\bar{D}^0$ mixing in the decay $D^0\rightarrow K^+\pi^-$ using a data sample of integrated luminosity 976 fb$^{-1}$ collected with the Belle detector at the KEKB $e^+e^-$ asymmetric-energy collider. We measure the mixing parameters ${x'}^2 = (0.09\pm0.22)\times 10^{-3}$ and $y' = (4.6\pm3.4)\times 10^{-3}$ and the ratio of doubly Cabibbo-suppressed to Cabibbo-favored decay rates $R_D = (3.53\pm0.13)\times 10^{-3}$, where the uncertainties are statistical and systematic combined. Our measurement excludes the no-mixing hypothesis at the 5.1 standard deviation level., Comment: 6 pages, 4 figures

Abstract: We find evidence for the semileptonic baryonic decay B−→pp¯ℓ−ν¯ℓ ( ℓ=e , μ ), based on a data sample of 772 million BB¯ pairs collected at the ϒ(4S) resonance with the Belle detector at the KEKB asymmetric-energy electron-positron collider. A neural-network based hadronic B -meson tagging method is used in this study. The branching fraction of B−→pp¯ℓ−ν¯ℓ is measured to be (5.8−2.1+2.4(stat)±0.9(syst))×10−6 with a significance of 3.2σ , where lepton universality is assumed. We also estimate the corresponding upper limit: B(B−→pp¯ℓ−ν¯ℓ)

Abstract: We report the first measurement of the lepton forward-backward asymmetry ${\cal A}_{\rm FB}$ for the inclusive electroweak penguin process $B \rightarrow X_s \ell^+ \ell^-$ as a function of $q^2=M_{\ell^+\ell^-}^2c^2$, where $\ell$ is an electron or a muon and $X_s$ is a hadronic recoil system with an $s$ quark. The results are based on a data sample containing $772\times10^6$ $B\bar{B}$ pairs recorded at the $\Upsilon(4S)$ resonance with the Belle detector at the KEKB $e^+ e^-$ collider. For $q^2 > 10.2$ GeV$^2$/$c^2$, ${\cal A}_{\rm FB} < 0$ is excluded at the 2.3$\sigma$ level, where $\sigma$ is the standard deviation. For $q^2 < 4.3$ GeV$^2$/$c^2$, the result is within 1.8$\sigma$ of the theoretical expectation.

Abstract: We present the results of an amplitude analysis of ${\overline{B}}^{0}\to J/\psi {K}^{-}{\pi }^{+}$ decays. A new charged charmoniumlike state ${Z}_{c}\left(4200{\right)}^{+}$ decaying to $J/\psi {\pi }^{+}$ is observed with a significance of $6.2\sigma $. The mass and width of the ${Z}_{c}\left(4200{\right)}^{+}$ are $419{6}_{-29-13}^{+31+17}\text{}\text{}\mathrm{MeV}/{c}^{2}$ and $37{0}_{-70-132}^{+70+70}\text{}\text{}\mathrm{MeV}$, respectively; the preferred assignment of the quantum numbers is ${J}^{P}={1}^{+}$. In addition, we find evidence for ${Z}_{c}\left(4430{\right)}^{+}\to \phantom{\rule{0ex}{0ex}}J/\psi {\pi }^{+}$. The analysis is based on a $711\text{}\text{}{\mathrm{fb}}^{-1}$ data sample collected by the Belle detector at the asymmetric-energy ${e}^{+}{e}^{-}$ collider KEKB.

Abstract: We report a measurement of ${D}^{0}\text{-}{\overline{D}}^{0}$ mixing parameters and a search for indirect $CP$ violation through a time-dependent amplitude analysis of ${D}^{0}\to {K}_{S}^{0}{\pi }^{+}{\pi }^{-}$ decays. The results are based on $921\text{}\text{}{\mathrm{fb}}^{-1}$ of data accumulated with the Belle detector at the KEKB asymmetric-energy ${e}^{+}{e}^{-}$ collider. Assuming $CP$ conservation, we measure the mixing parameters $x=\left(0.56±{0.19}_{-0.09-0.09}^{+0.03+0.06}\right)%$ and $y=\left(0.30±\phantom{\rule{0ex}{0ex}}{0.15}_{-0.05-0.06}^{+0.04+0.03}\right)%$, 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 $\mathrm{arg}\left(q/p\right)=\left(-6±11±{3}_{-4}^{+3}\right)°$ are found to be consistent with conservation of $CP$ symmetry in mixing and in the interference between mixing and decay, respectively.

Abstract: We present a measurement of the branching fractions and charge-parity-($CP$-)violating parameters in $B\to \omega K$ decays. The results are obtained from the final data sample containing $772×{10}^{6}$ $B\overline{B}$ pairs collected at the $\mathrm{Υ}\left(4S\right)$ resonance with the Belle detector at the KEKB asymmetric-energy ${e}^{+}{e}^{-}$ collider. We obtain the branching fractions $\mathcal{B}\left({B}^{0}\to \omega {K}^{0}\right)=\left(4.5±0.4\left(\text{stat}\right)±0.3\left(\text{syst}\right)\right)×{10}^{-6},\mathcal{B}\left({B}^{+}\to \omega {K}^{+}\right)=\phantom{\rule{0ex}{0ex}}\left(6.8±0.4\left(\text{stat}\right)±0.4\left(\text{syst}\right)\right)×{10}^{-6}$ which are in agreement with their respective current world averages. For the $CP$-violating parameters, we obtain ${\mathcal{A}}_{\omega {K}_{S}^{0}}=-0.36±0.19\left(\text{stat}\right)±0.05\left(\text{syst}\right),{\mathcal{S}}_{\omega {K}_{S}^{0}}=+0.91±0.32\left(\text{stat}\right)±0.05\left(\text{syst}\right),{\mathcal{A}}_{\omega {K}^{+}}=-0.03±0.04\left(\text{stat}\right)±0.01\left(\text{syst}\right),$ where $\mathcal{A}$ and $\mathcal{S}$ represent the direct and mixing-induced $CP$ asymmetry, respectively. We find no evidence of $CP$ violation in the decay channel ${B}^{+}\to \omega {K}^{+}$; however, we obtain the first evidence of $CP$ violation in the ${B}^{0}\to \omega {K}_{S}^{0}$ decay channel at the level of 3.1 standard deviations.

Abstract: We present a measurement of the branching fractions and charge-parity-(CP-) violating parameters in B -> omega K decays. The results are obtained from the final data sample containing 772 x 10^(6) BBbar pairs collected at the Y(4S) resonance with the Belle detector at the KEKB asymmetric-energy e+e- collider. We obtain the branching fractions B(B0 -> omega K0) = (4.5 +/- 0.4 (stat) +/- 0.3 (syst)) x 10^(-6), B(B- -> omega K-) = (6.8 +/- 0.4 (stat) +/- 0.4 (syst)) x 10^(-6), which are in agreement with their respective current world averages. For the CP violating parameters, we obtain A(B0 -> omega KS) = -0.36 +/- 0.19 (stat) +/- 0.05 (syst), S(B0 -> omega KS) = +0.91 +/- 0.32 (stat) +/- 0.05 (syst), A(B- -> omega 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-->omega K-; however, we obtain the first evidence of CP violation in the B0 -> omega KS decay channel at the level of 3.1 standard deviations., Comment: 25 pages, 5 figures, Submitted to PRD

Abstract: We report an observation of the $B^{\pm} \to J/\psi \eta K^{\pm}$ and $B^0 \to J/\psi \eta K^0_S$ decays using 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 obtain the branching fractions ${\cal B}(B^{\pm}\rightarrow J/\psi\eta K^{\pm})=(1.27\pm 0.11{\rm (stat.)\pm 0.11{\rm (syst.)})}\times10^{-4}$ and ${\cal B}(B^0\to J/\psi \eta K^0_S)=(5.22 \pm 0.78 {\rm(stat.)} \pm 0.49{\rm(syst.)})\times10^{-5}$. We search for a new narrow charmonium(-like) state $X$ in the $J/\psi \eta$ mass spectrum and find no significant excess. We set upper limits on the product of branching fractions, ${\cal B}(B^\pm \to XK^\pm){\cal B}(X \to J/\psi \eta)$, at 3872 MeV$/c^2$ where a $C$-odd partner of X(3872) may exist, at $\psi(4040)$ and $\psi(4160)$ assuming their known mass and width, and over a range from 3.8 to 4.8 GeV$/c^2$. % at a 5 MeV$/c^2$ step. The obtained upper limits at 90% confidence level for $X^{C{\rm -odd}}(3872)$, $\psi(4040)$ and $\psi(4160)$ are 3.8$\times 10^{-6}$, 15.5$\times 10^{-6}$ and 7.4$\times 10^{-6}$, respectively., Comment: Submitted to PTEP

Abstract: We report a study of the suppressed decay B^- -> DK^-, D -> K^+\pi^-\pi^0, where D denotes either a D^0 or a \bar{D}^0 meson. The decay is sensitive to the CP-violating parameter \phi_3. Using a data sample of 772 x 10^6 B\bar{B} pairs collected at the \Upsilon(4S) resonance with the Belle detector, we measure the ratio of branching fractions of the above suppressed decay to the favored decay B^- -> DK^-, D -> K^-\pi^+\pi^0. Our result is R_{DK} = [1.98 +/- 0.62(stat.) +/- 0.24(syst.)] x 10^{-2}, which indicates the first evidence of the signal for this suppressed decay with a significance of 3.2 standard deviations. We measure the direct CP asymmetry between the suppressed B^- and B^+ decays to be A_{DK} = 0.41 +/- 0.30 (stat.) +/- 0.05 (syst.). We also report measurements for the analogous quantities R_{D\pi} and A_{D\pi} for the decay B^- -> D\pi^-, D -> K^+\pi^-\pi^0., Comment: 7 pages, 3 figures, Accepted by Phys. Rev.

Abstract: We report a measurement of the branching fraction of the decay $B^0_s\to J/\psi\,\phi(1020)$, evidence and a branching fraction measurement for $B^0_s\to J/\psi\,f'_2(1525)$, and the determination of the total $B^0_s\to J/\psi\,K^+K^-$ branching fraction, including the resonant and non-resonant contributions to the $K^+K^-$ channel. We also determine the $S$-wave contribution within the $\phi(1020)$ mass region. The absolute branching fractions are $\mathcal{B}[B^0_s\to J/\psi\,\phi(1020)]=(1.25 \pm 0.07\left(\mathrm{stat}\right)\pm 0.08\left(\mathrm{syst}\right)\pm 0.22\left(f_s\right))\times 10^{-3}$, $\mathcal{B}[B^0_s\to J/\psi\,f'_2(1525)]=(0.26\pm 0.06\left(\mathrm{stat}\right)\pm 0.02\left(\mathrm{syst}\right) \pm 0.05\left(f_s\right))\times 10^{-3}$ and $\mathcal{B}[B^0_s\to J/\psi\,K^+K^-] = (1.01\pm 0.09\left(\mathrm{stat}\right) \pm 0.10\left(\mathrm{syst}\right)\pm 0.18\left(f_s\right))\times 10^{-3}$, where the last systematic error is due to the branching fraction of $b\bar{b}\to B^{(*)}_s B^{(*)}_s$. The branching fraction ratio is found to be $\mathcal{B}[B^0_s\to J/\psi\,f'_2(1525)]/\mathcal{B}[B^0_s\to J/\psi\,\phi(1020)]=(21.5\pm 4.9\left(\mathrm{stat}\right) \pm2.6\left(\mathrm{syst}\right))%$.

Abstract: Using data samples of 89 fb$^{-1}$, 703 fb$^{-1}$, and 121 fb$^{-1}$ collected with the Belle detector at the KEKB asymmetric-energy $e^+e^-$ collider at center-of-mass energies 10.52 GeV, 10.58 GeV, and 10.876 GeV, respectively, we study the exclusive reactions $e^+e^- \to \omega\pi^0$, $K^{\ast}(892)\bar{K}$, and $K_2^{\ast}(1430)\bar{K}$ (Charge-conjugate modes are included implicitly). Significant signals of $\omega\pi^0$, $K^{\ast}(892)^0\bar{K}^0$, and $K_2^{\ast}(1430)^-K^+$ are observed for the first time at these energies, and the energy dependencies of the cross sections are presented. On the other hand, no significant excesses for $K^{\ast}(892)^-K^+$ and $K_2^{\ast}(1430)^0 \bar{K}^0$ are found, and we set limits on the cross section ratios $R_{\rm VP} = \frac{\sigma_B(e^+e^-\to K^{\ast}(892)^0\bar K^0)} {\sigma_B(e^+e^-\to K^{\ast}(892)^-K^+)}>$ 4.3, 20.0, and 5.4, and $R_{\rm TP} = \frac{\sigma_B(e^+e^-\to K_2^{\ast}(1430)^0\bar K^0)} {\sigma_B(e^+e^-\to K_2^{\ast}(1430)^-K^+)}, Comment: 17 pages, 4 figures; accepted for publication as a Regular Article in Physical Review D

Using 791 fb-1 of data collected with the Belle detector, we obtain a branching fraction ratio of R_WS = [0.324 +- 0.008 (stat) +- 0.007 (sys)]%. Multiplying this ratio by the world average value for the branching fraction B(D0 -> K- pi+ pi+ pi-) gives a branching fraction B(D0 -> K+ pi- pi+ pi-) = (2.61 +- 0.06 +0.09 -0.08) x 10-4., Comment: 14 pages, 1 figure, 1 table, submitted to Physical Review D

Abstract: We perform a full amplitude analysis of B0 -> psi' K+ pi- decays, with psi' -> mu+ mu- or e+ e-, to constrain the spin and parity of the Z(4430)-. The J^P=1+ hypothesis is favored over the 0-, 1-, 2- and 2+ hypotheses at the levels of 3.4 sigma, 3.7 sigma, 4.7 sigma and 5.1 sigma, respectively. The analysis is based on a 711 fb^-1 data sample that contains 772x10^6 B B pairs, collected at the Y(4S) resonance by the Belle detector at the asymmetric-energy e+ e- collider KEKB., 13 pages, 14 figures

Abstract: We report the results of a study of the exclusive semileptonic decays B->pi0lnu, B->pi+lnu, B->rho0lnu, B->rho+lnu and B->omegalnu, where l represents an electron or a muon. The events are tagged by fully reconstructing a second B meson in the event in a hadronic decay mode. The measured branching fractions are Br(B->pi0lnu) = (0.80 +- 0.08 +- 0.04)x10^-4, Br(B->pi+lnu) = (1.49 +- 0.09 +- 0.07)x10^-4, Br(B->rho0lnu) = (1.83 +- 0.10 +- 0.10)x10^-4, Br(B->rho+lnu) = (3.22 +- 0.27 +- 0.24)x10^-4, and Br(B->omegalnu) =(1.07 +- 0.16 +- 0.07)x10^-4, where the first error is statistical and the second one is systematic. The obtained branching fractions are inclusive of soft photon emission. We also determine the branching fractions as a function of the 4-momentum transfer squared to the leptonic system q^2=(p_l+p_nu)^2, where p_l and p_nu are the lepton and neutrino 4-momenta, respectively. Using the pion modes, a recent LCSR calculation, lattice QCD results and a model-independent description of the hadronic form factor, a value of the CKM matrix element |V_{ub}| = (3.52 +- 0.29)x10^-3 is extracted. For the first time, a charmless state with invariant mass greater than 1 GeV/c^2, which might be dominated by the decay B->f2lnu, is observed. These results are obtained from a 711 1/fb data sample that contains 772 millions BB pairs, collected near the Upsilon(4S) resonance with the Belle detector at the KEKB asymmetric-energy e^+ e^- collider., Comment: To be submitted to PRD

Abstract: Using samples of 102 million $\Upsilon(1S)$ and 158 million $\Upsilon(2S)$ events collected with the Belle detector, we study exclusive hadronic decays of these two bottomonium resonances to $\ks K^+ \pi^-$ and charge-conjugate (c.c.) states, $\pi^+ \pi^- \pi^0 \pi^0$, and $\pi^+ \pi^- \pi^0$, and to the two-body Vector-Pseudoscalar ($K^{\ast}(892)^0\bar{K}^0+ {\rm c.c.}$, $K^{\ast}(892)^-K^+ + {\rm c.c.}$, $\omega\pi^0$, and $\rho\pi$) final states. For the first time, signals are observed in the modes $\Upsilon(1S) \to \ks K^+ \pi^- + {\rm c.c.}$, $\pi^+ \pi^- \pi^0 \pi^0$, and $\Upsilon(2S) \to \pi^+ \pi^- \pi^0 \pi^0$, and evidence is found for the modes $\Upsilon(1S)\to \pi^+ \pi^- \pi^0$, $K^{\ast}(892)^0 \bar{K}^0+ {\rm c.c.}$, and $\Upsilon(2S) \to \ks K^+ \pi^- + {\rm c.c.}$ Branching fractions are measured for all the processes, while 90% confidence level upper limits on the branching fractions are also set for the modes with a statistical significance of less than $3\sigma$. The ratios of the branching fractions of $\Upsilon(2S)$ and $\Upsilon(1S)$ decays into the same final state are used to test a perturbative QCD prediction for OZI-suppressed bottomonium decays., Comment: 8 pages, 3 figures, 2 tables, accepted for publication as a Rapid Communication in Physical Review D

Abstract: We report measurements of $B \to \chi_{c1} \gamma K$ and $\chi_{c2} \gamma K$ decays using $772 \times 10^{6}$ $B\bar{B}$ events collected at the $\Upsilon(4S)$ resonance with the Belle detector at the KEKB asymmetric-energy $e^+e^-$ collider. Evidence of a new resonance in the $\chi_{c1} \gamma$ final state is found with a statistical significance of $3.8 \sigma$. This state has a mass of $3823.1 \pm 1.8 {(stat)} \pm 0.7 {(syst)}$ MeV/$c^2$, a value that is consistent with theoretical expectations for the previously unseen $1^3 D_2$ $c\bar{c}$ meson. We find no other narrow resonance and set upper limits on the branching fractions of the $X(3872) \to \chi_{c1} \gamma$ and $\chi_{c2} \gamma$ decays., Comment: 7 pages, 4 figures

Abstract: The cross section for $e^+ e^- \to \pi^+ \pi^- J/\psi$ between 3.8 GeV 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 parameterization with properties that are consistent with the Y(4008) state that was previously reported by Belle. In a study of $Y(4260) \to \pi^+ \pi^- J/\psi$ decays, a structure is observed in the $M(\pi^\pm\jpsi)$ mass spectrum with $5.2\sigma$ significance, with mass $M=(3894.5\pm 6.6\pm 4.5) {\rm MeV}/c^2$ and width $\Gamma=(63\pm 24\pm 26)$ MeV/$c^{2}$, where the errors are statistical and systematic, respectively. This structure can be interpreted as a new charged charmonium-like state., Comment: 10 pages, 5 figures, 2 tables, accepted by Phys. Rev. Lett

Abstract: We report a search for the rare decays B -> h(*) nu nubar, where h(*) stands for K+, Ks0, K*+, K*0, pi+, pi0, rho+, rho0 and phi. The results are obtained from a 711 fb-1 data sample that contains 772 million BB pairs collected at the Y(4S) resonance with the Belle detector at the KEKB e+e- collider. We search for signal candidates by fully reconstructing a hadronic decay of the accompanying B meson and requiring a single h(*) meson left on the signal side. No significant signal is observed and we set upper limits on the branching fractions at 90% confidence level. The measurements of B+ -> K*+ nu nubar, B+ -> pi+ nu nubar, B0 -> pi0 nu nubar and B0 -> rho^0 nu nubar provide the world's currently most restrictive limits.

Abstract: We present a measurement of the time-dependent charge-parity (CP) violation parameters in B0 -> pi+ pi- decays. The results are obtained from the final data sample containing 772 million BBbar 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 Acp = +0.33 +/- 0.06 (stat) +/- 0.03 (syst) and Scp = -0.64 +/- 0.08 (stat) +/- 0.03 (syst), where Acp and Scp represent the direct and mixing-induced CP asymmetry, respectively. Using an isospin analysis including results from other Belle measurements, we find 23.8 < phi2 < 66.8 degrees is disfavored at the 1 sigma level, where phi2 is one of the three interior angles of the CKM unitarity triangle related to B_{u,d} decays., Comment: 16 pages, 5 figures, CKM2012 conference paper, Submitted to PRD
