Description

Measurements of decay-time dependent CP violation are chief goals of the Belle II physics program. Comparison between penguin-dominated $b\to q\bar{q}s$ and tree-dominated $b\to c\bar{c}s$ results allows for stringent tests of CKM unitarity that are sensitive to non-SM physics. This talk present first Belle II results on the mixing rate and lifetime of $B^0$ mesons, an essential validation of time-dependent measurements that requires detailed control of complex high-level capabilities such as flavor tagging and decay-time resolution modeling. Recent results on $B^0\to K^0_S\pi^0\gamma$ and $B^0\to K_S^0K_S^0K_S^0$ are also reported.
