Belle II

Introduction

The two B-factory experiments (Belle at KEKB, BaBar at PEPII) observed the first large signals for CP violation (matter-antimatter asymmetries) in the B meson sector in 2001. These results demonstrated Kobayashi and Maskawa's hypothesis for the origin of the CP violation is correct and provided the experimental foundation for their 2008 Nobel Prize in Physics. Belle II, the first super B-Factory experiment, is designed to make precise measurements of weak interaction parameters and find NP (New Physics) beyond the Standard Model of particle physics. In June 2022, SuperKEKB, the asymmetric energy e+e- Super B factory, achieved a new luminosity world record, 4.7x1034 cm-2s-1.
