Abstract: In the Standard Model (SM) charmless hadronic decays $B_s^0 \rightarrow ��^\prime ��$ proceed via tree-level $b\to u$ and penguin $b\to s$ transitions. Penguin transitions are sensitive to Beyond-the-Standard-Model (BSM) physics scenarios and could affect the branching fractions and {\it CP} asymmetries in such decays. Once branching fractions for two-body decays $B_s \to ��, ��^{\prime}, ��^{\prime}��^{\prime} $ are measured, and the theoretical uncertainties are reduced, it would be possible to extract {\it CP} violating parameters from the data using the formalism based on SU(3)/U(3) symmetry. To achieve this goal, at least four of these six branching fractions need to be measured. Only the branching fraction for $B_s^0 \to ��^{\prime}��^{\prime}$ has been measured so far.

Abstract: We report results from a study of hadronic transitions of the $��_{bJ}(nP)$ states of bottomonium at Belle. The $P$-wave states are reconstructed in transitions to the $��(1S)$ with the emission of an $��$ meson. The transitions of the $n=2$ triplet states provide a unique laboratory in which to study nonrelativistic quantum chromodynamics, as the kinematic threshold for production of an $��$ and $��(1S)$ lies between the $J=0$ and $J=1$ states. A search for the $��_{bJ}(3P)$ states is also reported.

Abstract: We report the first measurement of the $D^{\ast -}$ meson polarization in the decay $B^0 \to D^{*-} ��^+��_��$ using the full data sample of 772$\times 10^6$ $B\bar{B}$ pairs recorded with the Belle detector at the KEKB electron-positron collider. Our result, $F_L^{D^\ast} = 0.60 \pm 0.08 ({\rm stat}) \pm 0.04 ({\rm sys})$, where $F_L^{D^\ast}$ denotes the $D^{\ast-}$ meson longitudinal polarization fraction, agrees within about $1.7$ standard deviations of the standard model prediction., 16 pages, 4 figures, CKM 2018

Abstract: The precise determination of the CKM matrix element $\left| V_{cb}\right|$ is important for carrying out tests of the flavour sector of the Standard Model. In this article we present a preliminary analysis of the $\bar B^0 \to D^{*\,+} \, \ell^- \, \bar ��_\ell$ decay mode and its charge conjugate, selected in events that contain a fully reconstructed $B$-meson, using 772 million $e^+ \, e^- \to ��(4S) \to B \bar B$ events recorded by the Belle detector at KEKB. Unfolded differential decay rates of four kinematic variables fully describing the $\bar B^0 \to D^{*\,+} \, \ell^- \, \bar ��_\ell$ decay in the $B$-meson rest frame are presented. We measure the total branching fraction $\mathcal{B}( \bar B^0 \to D^{*\,+} \, \ell^- \, \bar ��_\ell ) = \left(4.95 \pm 0.11 \pm 0.22 \right) \times 10^{-2}$, where the errors are statistical and systematic respectively. The value of $\left|V_{cb} \right|$ is determined to be $\left( 37.4 \pm 1.3 \right) \times 10^{-3}$. Both results are in good agreement with current world averages.

Abstract: We present a measurement of the Michel parameters of the $��$ lepton, $\bar��$ and $��$, in the radiative leptonic decay $��^- \rightarrow \ell^- ��_�� \bar��_{\ell} ��$ 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 $e^+e^-\rightarrow��^+��^-\rightarrow (��^+��^0 \bar��_��)(\ell^-��_��\bar��_{\ell}��)$ $(\ell=e$ or $��)$. The measured values of the Michel parameters are $\bar�� = -1.3 \pm 1.5 \pm 0.8$ and $��= 0.5 \pm 0.4 \pm 0.2$, 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: We report the first observation of the polarization of $��/\bar��$ hyperons transverse to its production plane in $e^+e^-$ annihilation. We observe a significant polarization that rises with the fractional energy carried by the hyperon as well as its transverse momentum. To define the production plane, we use the direction of the hyperon momentum together with either the thrust axis in the event or the momentum vector of a hadron in the opposite hemisphere. Furthermore, we investigate the contributions to the hyperon polarization from the feed-down from $��^0/\bar��^0$ and $��_c^{\pm}$ decays. This measurement uses a dataset of 800.4fb$^{-1}$ collected by the Belle experiment at or near a center-of-mass energy of 10.58 GeV., 14 pages, 7 figures

Abstract: We present the first measurement of the Michel parameters $\bar��$ and $��$ in the radiative leptonic decay of the $��$ 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 $e^+e^-\rightarrow��^+��^-\rightarrow (��^+��^0 \bar��)(l^-��\bar��)$ $(l=e$ or $��)$. The preliminary values of the measured Michel parameters are $\bar�� = -2.0 \pm 1.5 \pm 0.8$ and $��= 0.6 \pm 0.4 \pm 0.2$, where the first error is statistical and the second is systematic.

Abstract: We report the first measurement of the $��$ lepton polarization in the decay ${\bar B} \rightarrow D^* ��^- {\bar��_��}$ as well as a new measurement of the ratio of the branching fractions $R(D^{*}) = \mathcal{B}({\bar B} \rightarrow D^* ��^- {\bar��_��}) / \mathcal{B}({\bar B} \rightarrow D^* \ell^- {\bar��_{\ell}})$, where $\ell^-$ denotes an electron or a muon, with the decays $��^- \rightarrow ��^- ��_��$ and $��^- \rightarrow ��^- ��_��$. We use the full data sample of $772 \times 10^6$ $B{\bar B}$ pairs accumulated with the Belle detector at the KEKB electron-positron collider. Our preliminary results, $R(D^*) = 0.276 \pm 0.034{\rm (stat.)} ^{+0.029} _{-0.026}{\rm (syst.)}$ and $P_�� = -0.44 \pm 0.47 {\rm (stat.)} ^{+0.20} _{-0.17} {\rm (syst.)}$, are consistent with the theoretical predictions of the Standard Model within $0.6$ standard deviation., 31 pages, 6 figures, ICHEP 2016

Abstract: We report a study of radiative decays of ��_{bJ}(1P)(J=0,1,2) mesons into 74 hadronic final states comprising charged and neutral pions, kaons, protons; out of these, 41 modes are observed with at least 5 standard deviation significance. Our measurements not only improve the previous measurements by the CLEO Collaboration but also lead to first observations in many new modes. The large sample allows us to probe the total decay width of the ��_{b0}(1P). In the absence of a statistically significant result, a 90% confidence-level upper limit is set on the width at ��_{total}< 2.4 MeV. Our results are based on 24.7 fb^{-1} of e+e- collision data recorded by the Belle detector at the ��(2S) resonance, corresponding to (157.8\pm3.6)\times10^6 ��(2S) 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 report a measurement of the amplitude ratio $r_S$ of $B^0 \to D^0K^{*0}$ and $B^0 \to \bar{D^0}K^{*0}$ decays with a model-independent Dalitz plot analysis using $D\to K_S^0��^+��^-$ decays. Using the full data sample of $772\times10^6$ $B\bar{B}$ pairs collected at the $��(4S)$ resonance with the Belle detector at KEKB accelerator the upper limit is $r_S < 0.87$ at the 68 % confidence level. This result is the first measurement of $r_S$ with a model-independent Dalitz analysis, and is consistent with results from other analyses. The value of $r_S$ indicates the sensitivity of the decay to $��_3$ because the statistical uncertainty is proportional to $1/r_S$. The $r_S$ result is obtained from observables ($x_\pm$, $y_\pm$) \begin{eqnarray} x_- &=& +0.4 ^{+1.0 +0.0}_{-0.6 -0.1} \pm0.0 \\ y_- &=& -0.6 ^{+0.8 +0.1}_{-1.0 -0.0} \pm0.1 \\ x_+ &=& +0.1 ^{+0.7 +0.0}_{-0.4 -0.1} \pm0.1 \\ y_+ &=& +0.3 ^{+0.5 +0.0}_{-0.8 -0.1} \pm0.1 \\ , \end{eqnarray} where $x_\pm = r_S \cos(��_S \pm ��_3)$, $y_\pm = r_S \sin(��_S \pm ��_3)$ and $��_3 (��_S)$ are the weak (strong) phase difference between $B^0 \to D^0K^{*0}$ and $B^0 \to \bar{D^0}K^{*0}$. The first uncertainty is statistical, the second is the experimental systematic and the third is the systematic due to the uncertainties on $c_i$ and $s_i$ parameters measured by CLEO.

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)

Abstract: We report measurements of B??c1?K and ?c2?K decays using 772�106 BB? events collected at the ?(4S) resonance with the Belle detector at the KEKB asymmetric-energy e+e- collider. Evidence of a new resonance in the ?c1? final state is found with a statistical significance of 3.8?. This state has a mass of 3823.1�1.8(stat)�0.7(syst) MeV/c2, a value that is consistent with theoretical expectations for the previously unseen 1D23 cc? meson. We find no other narrow resonance and set upper limits on the branching fractions of the X(3872)??c1? and ?c2? decays. � 2013 American Physical Society.

Abstract: Physical review letters 126(16), 161801 (2021). doi:10.1103/PhysRevLett.126.161801, We present a measurement of $R_{K^{\ast}}$, the ratio of the branching fractions ${\cal B}(B\to K^\ast \mu^+ \mu^-)$ and ${\cal B}(B\to K^\ast e^+ e^-)$, for both charged and neutral $B$ mesons. The ratio for charged $B$ mesons, $R_{K{^{\ast +}}}$, is the first measurement ever performed. The analysis is based on a data sample of $711~\mathrm{fb}^{-1}$, containing $772\times 10^{6}$ $B\bar B$ events, recorded at the $\Upsilon(4S)$ resonance with the Belle detector at the KEKB asymmetric-energy $e^+e^-$ collider. The obtained results are consistentwith Standard Model expectations., Published by APS, College Park, Md.

Abstract: Journal of high energy physics 2021(10), 019 (2021). doi:10.1007/JHEP10(2021)019, Charged lepton flavor violation is forbidden in the Standard Model but possible in several new physics scenarios. In many of these models, the radiative decays $\tau^{\pm}\rightarrow\ell^{\pm}\gamma$ ($\ell=e,\mu$) are predicted to have a sizeable probability, making them particularly interesting channels to search at various experiments. An updated search via $\tau^{\pm}\rightarrow\ell^{\pm}\gamma$ using full data of the Belle experiment, corresponding to an integrated luminosity of 988 fb$^{-1}$, is reported for charged lepton flavor violation. No significant excess over background predictions from the Standard Model is observed, and the upper limits on the branching fractions, $\mathcal{B}(\tau^{\pm}\rightarrow \mu^{\pm}\gamma)$$\leq$$4.2\times10^{-8}$ and $\mathcal{B}(\tau^{\pm}\rightarrow e^{\pm}\gamma)$$\leq$$5.6\times10^{-8}$, are set at 90% confidence level., Published by SISSA, [Trieste]

Abstract: We present an extraction of azimuthal correlations between two pairs of charged pions detected in opposite jets from electron-positron annihilation. These correlations may arise from the dependence of the di-pion fragmentation on the polarization of the parent quark in the process $e^+e^- \rightarrow q \bar{q}$. Due to the correlation of the quark polarizations, the cross-section of di-pion pair production, in which the pion pairs are detected in opposite jets in a dijet event, exhibits a modulation in the azimuthal angles of the planes containing the hadron pairs with respect to the production plane. The measurement of this modulation allows access to combinations of fragmentation functions that are sensitive to the quark's transverse polarization and helicity. Within our uncertainties we do not observe a significant signal from the previously unmeasured helicity dependent fragmentation function $G_1^\perp$. This measurement uses a dataset of 938~fb$^{-1}$ collected by the Belle experiment at or near $\sqrt{s}\approx10.58$ GeV., 11 pages, 2 figures

Abstract: We report a measurement of the ratios of branching fractions $\mathcal{R}(D) = {\cal B}(\bar{B} \to D \tau^- \bar{\nu}_{\tau})/{\cal B}(\bar{B} \to D \ell^- \bar{\nu}_{\ell})$ and $\mathcal{R}(D^{\ast}) = {\cal B}(\bar{B} \to D^* \tau^- \bar{\nu}_{\tau})/{\cal B}(\bar{B} \to D^* \ell^- \bar{\nu}_{\ell})$, where $\ell$ denotes an electron or a muon. The results are based on a data sample containing $772\times10^6$ $B\bar{B}$ events recorded at the $\Upsilon(4S)$ resonance with the Belle detector at the KEKB $e^+ e^-$ collider. The analysis utilizes a method where the tag-side $B$ meson is reconstructed in a semileptonic decay mode, and the signal-side $\tau$ is reconstructed in a purely leptonic decay. The measured values are $\mathcal{R}(D)= 0.307 \pm 0.037 \pm 0.016$ and $\mathcal{R}(D^{\ast})= 0.283 \pm 0.018 \pm 0.014$, where the first uncertainties are statistical and the second are systematic. These results are in agreement with the Standard Model predictions within $0.2$ and $1.1$ standard deviations, respectively, while their combination agrees with the Standard Model predictions within $1.2$ standard deviations., Comment: 12 pages, 6 figures
