Recent highlights from the BELLE and BELLE II experiments

The BELLE experiment at the KEKB collider in Tsukuba operated as a B-factory until 2018, making significant contributions to flavor physics. Building on this legacy, the BELLE II experiment, an upgraded version, now operates at the SuperKEKB energy-asymmetric e + e − collider. BELLE II has collected 424 fb − 1 of data, including 365 fb − 1 at the ϒ ( 4 S ) resonance. A wide range of physics topics can be studies with this data. In this proceeding, we review our latest results, which include tests of lepton flavor universality, Cabibbo-Kobayashi-Maskawa physics, searches for rare B -meson decays, and spectroscopy studies. We also discuss contributions to the g μ − 2 prediction.
