Measurement of the branching fraction for the decay $B \to K^{\ast}(892)\ell^+\ell^-$ at Belle IIPublic
We report a measurement of the branching fraction of $B \to K^{\ast}(892)\ell^+\ell^-$ decays, where $\ell^+\ell^- = \mu^+\mu^-$ or $e^+e^-$, using electron-positron collisions recorded at an energy at or near the $\Upsilon(4S)$ mass and corresponding to an integrated luminosity of $189$ fb$^{-1}$. The data was collected during 2019--2021 by the B… |

Hadronic $B$ decays at Belle IIPublic
We report on recent measurements of hadronic $B$ decays using the data set collected from 2019 to 2021 by the Belle~II experiment and corresponding to an integrated luminosity of 189.8 ${\rm fb^{-1}}$. We present the measurement of the CKM angle $\gamma$, performed combining Belle~II data with the full Belle data set, and measurements of $B^0-\bar… |

Measurement of the branching fractions and CP asymmetries of B+ → π+π0 and B+ → K+π0 decays in 2019-2021 Belle II dataPublic
We determine the branching fractions B and CP asymmetries ACP of the decays B+ → π+π0 and B+ → K+π0. The results are based on a data set containing 198 million bottom-antibottom meson pairs corresponding to an integrated luminosity of 190 fb−1 recorded by the Belle II detector in energy-asymmetric electron-positron collisions at the Υ (4S) resonan… |

Semileptonic and rare decays at Belle IIPublic
The Belle II collaboration presents their first measurements of the magnitude of the Cabibbo-Kobayashi-Maskawa matrix elements $|V_{cb}|$ and $|V_{ub}|$, as well as their first branching fraction measurement of $B\rightarrow K^*\ell^+\ell^-$ based on up to 189.26 fb$^{-1}$ of data collected at the $\Upsilon(4S)$ resonance. In all presented analyse… |

Measurement of decay-time dependent CP violation in B0 → KS0KS0KS0 using 2019--2021 Belle II dataPublic
We report a measurement of decay-time dependent CP-violating parameters in B0 → KS0KS0KS0 decays. We use $(198.0 \pm 3.0) \times 10^6\ \BB$ pairs collected at the \FourS resonance with the Belle II detector at the SuperKEKB asymmetric-energy $e^+e^-$ collider. The observed mixing-induced and direct \cp violation parameters are $\scp = -1.86\ _{-0.… |

Recent results from Belle and Belle IIPublic
I will report recent results from Belle and Belle II with the main emphasis on the CKM parameter determinations, lepton flavor universality test, isospin rum rule test, EW and radiative penguin measurement, dark-sector particle search, Y(10753) property determination, and charmed-baryon lifetime measurement. |

The use of weak reactions to learn about hadron interactions at Belle IIPublic
The Belle II experiment at the SuperKEKB energy-asymmetric electron-positron collider is a major upgrade of the B factory experiment at KEK in Tsukuba, Japan. With a goal of collecting 50 times the data recorded by its predecessor, Belle II has an expansive program in hadronic spectroscopy. Many early measurements have proven the capabilities of t… |

$R(D^{*})$ measurement using the hadronic tag algorithm at the Belle II experimentPublic
In the semileptonic decay of $B$ mesons, the global average of $R(D^{*})$ measurement deviates from the Standard Model by $3.3\sigma$. It indicates a violation of the lepton universality. We will measure $R(D^{*})$ for the validation of this deviation using the Belle II data, which are independent of the previous measurements’ data. We have develo… |
