Abstract

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.

BELLE 和 BELLE II 实验的最新亮点

筑波 KEKB 对撞机上的 BELLE 实验作为 B 工厂一直运行到 2018 年，为味物理学做出了重大贡献。在此基础上，BELLE II 实验（升级版）目前在超级 KEKB 能量不对称 e+e 对撞机上运行。BELLE II 已经收集了 424fb-1 的数据，包括在ϒ(4S)共振处收集的 365fb-1 数据。利用这些数据可以研究广泛的物理学课题。在本论文中，我们回顾了我们的最新成果，其中包括轻子味道普遍性的检验、卡比布-小林-马斯卡瓦物理学、稀有B介子衰变的搜索以及光谱学研究。我们还讨论了对 gμ-2 预测的贡献。
