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 $424{\text{fb}}^{-1}$ of data, including $365{\text{fb}}^{-1}$ at the $\Upsilon \left(4S\right)$ 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 $g_{\mu }-2$ prediction.
