Measurements of the ratio of partial widths: $\Gamma(D^{*+}_{s} \to D_{s}^{+}\pi^{0})/\Gamma(D_{s}^{*+} \to D_{s}^{+ }\gamma)$Public
We demonstrate the feasibility studies to measure the ratio of partial widths $\Gamma(D_{s}^{*+ } \to D_{s}^{+ }\pi^{0})/\Gamma(D_{s}^{*+} \to D_{s}^{+}\gamma)$ with the Belle II detector. |

Recent results from the Belle II experimentPublic
The Belle II experiment at the SuperKEKB asymmetric-energy electron-positron collider is collecting the world’s high-intensity collisions at the $\Upsilon$(4S) since 2019. A data set comparable in size to that of predecessor experiments, and collected with a new detector, enables unique or world-leading results in indirect searches for non-standar… |

Recent quarkonium results at Belle IIPublic
Belle II offers unique possibilities for the discovery and interpretation of exotic multi-quark states to probe the fundamentals of QCD. This talk presents recent results on searches for the hidden bottom transition between Upsilon(10750) and chi_bJ, measurements of the energy dependence of the e^+e^- -> B^(*)B^(*)-bar cross section, and searches … |

Particle identification using Ks->\pi^{+}\pi^{-} decayPublic
Particle identification performance for charged pions is studied using a Belle II simulated sample of Ks0 −→ π+π−. The relative difference between true efficiencies and that obtained from the sPlot technique is studied for different pion-identification criteria in bins of pion momenta. |

Measurement of time-integrated raw asymmetry in D0->K^{+}K^{−} decayPublic
Current experimental measurements of the CP asymmetry (ACP ) in D0 -> K0s Ks0 decay are limited by the statistical precision, with the best measurement performed by Belle experiment using 921 fb−1 of data. Using D0->K^{+}K^{−} as a control mode reduces the uncertainty in ACP in addition to making the analysis simpler. In this work, we report the p… |

Recent BelleII results on BSM physicsPublic
We report on recent results obtained by the Belle II experiment related to searches for beyond the standard model physics. The B meson decay data sample used corresponds to an integrated luminosity of $L = 189$ fb$^{-1}$. In recent years, discrepancies from standard-model predictions, which suggest violation of lepton-flavor universality, have eme… |

Recent Belle II results on hadronic B decaysPublic
We report on recent measurements of $B$ meson decays to hadronic final states using electron-positron collisions at the $\Upsilon(4S)$ resonance collected from 2019 to 2022 by the Belle~II experiment and corresponding to an integrated luminosity of 362 ${\rm fb^{-1}}$. We present new results to determine the quark-mixing parameter $\gamma$, perfor… |

Studies on $\tau$ decays at Belle IIPublic
Tau leptons offer a very clean environment to study the process of hadronization and are powerful tools to probe physics beyond the Standard Model (SM), which might be enhanced due to mass-dependent couplings. The Belle II experiment, installed at SuperKEKB asymmetric energy electron-positron collider, will collect the world’s largest sample of ta… |

Status and prospects for rare B decays at Belle and Belle IIPublic
Rare $B$ decays are at the front of Belle~II physics program. As the Belle~II experiment concludes three years of data taking, collecting a sample of roughly $\SI{424}{fb^{-1}}$ -- in size comparable to BaBar's and around half of Belle's --, first results on rare $B$ decays have already been shown since 2021. The latest is the inclusive $\mathcal{… |
