Time-dependent, hadronic B decays and electroweak penguins at Belle II

25 April 2023

Abstract: We report the recent measurements performed using the data sample collected from 2019 to 2022 by the Belle II experiment 1 at Υ(4S) resonance, corresponding to an integrated luminosity of 362 fb−1 . We present the measurement of B lifetime and mixing frequency, the time dependent CP-violation analyses using the B0 → JψKS0 , B0 → φKS0 , B0 → KS0 KS0 KS0 , B0 → KS0 π0 decays and the implication of the latter for the isospin sum rule, the observation of B → D(∗)K−KS0 decays, the analysis of B → Xsγ. We also present the measurements of the angle γ using B → DK decays, with the combined dataset collected by Belle and Belle II.
