Determination of $|V_{cb}|$ from $B\to D\ell\nu$ decays using 2019--2021 Belle II data Public
We present a determination of the magnitude of the Cabibbo-Kobayashi-Maskawa (CKM) matrix element $V_{cb}$ using the decay $B\to D\ell\nu$ based on $e^+e^-\to\Upsilon(4S)$~data recorded by the Belle II detector and corresponding to \lumi of integrated luminosity. The semileptonic decays \ensuremath{\Bz \to D^{-}(\to K^+ \pi^- \pi^-) \ell^{+} \nu_\… |

Search fro a stable double strange hexaquark at Belle IIPublic
QCD-motivated models for hadrons predict a wide variety of multi-quark states beyond ordinary mesons and baryons, known as exotic states. The first observation of a heavy exotic state by Belle in 2003 has triggered a huge experimental effort, and the last 20 years have marked a turning point in the field. To date, states composed of four and five … |

Recent results from the Belle~II experimentPublic
Belle II is a flavor physics experiment at the SuperKEKB $e^+e^-$ collider. It has accumulated $380~\fbi$ of data as of May 2022, and has obtained several results with the world's best precision or sensitivity. Recent results mainly with $190~\fbi$ of data are presented. |

Determination of $|V_{ub}|$ from untagged $B^0\to\pi^- \ell^+ \nu_{\ell}$ decays using 2019-2021 Belle~II dataPublic
We present an analysis of the charmless semileptonic decay $B^0\to\pi^- \ell^+ \nu_{\ell}$, where $\ell = e, \mu$, from 198.0 million pairs of $B\bar{B}$ mesons recorded by the Belle~II detector at the SuperKEKB electron-positron collider. The decay is reconstructed without identifying the partner $B$ meson. The partial branching fractions are mea… |

Lepton flavor universality at Belle and Belle IIPublic
The rate of semitauonic and electroweak penguin decays in the B sector show hints of lepton-flavor universality violation. Belle and Belle II data is well suited to probe such anomalies. The low-background collision environment along with the possibility of partially or fully reconstructing one of the two B mesons in the event offer high precision… |

LFU measurements in semileptonic b->c,l,nu decaysPublic
The rate of semitauonic B decays has been consistently above theory expectations since these decays were first measured. Recently significant differences between the forward-backward asymmetry in B→D∗eν and B→D∗μν were also reported. This talk presents recent results on lepton flavor universality tests from Belle II and LHCb. |

Electroweak and radiative penguin decays at Belle IIPublic
Decays of B mesons that proceed through electroweak penguin amplitudes attract significant attention due to a number of observed discrepancies between the standard-model predictions and the results. Belle II is expected to perform measurements on channels closely related to those exhibiting anomalies and that are uniquely available to Belle II. Th… |

Overview of CP-violation measurements at Belle IIPublic
In 2022 Belle II experiment performed several time-dependent measurements analysing 200M of the BB decays. In these measurements, the positions of the displaced B vertexes are measured which requires excellent vertex resolution as well as knowledge of the interaction region properties. Measurements include the determination of the B0 meson lifetim… |

Measurements of charm lifetimes at Belle IIPublic
We report on absolute lifetime measurements of charmed hadrons using the data collected by the Belle II experiment between 2019 and 2021. The measured lifetimes of $D^0$, $D^+$, and $\Lambda_c^+$ are the most precise to date and consistent with previous measurements. Our result indicates that $\Omega_c^0$ is not the shortest-lived singly charmed b… |
