Belle II

• New record of luminosity all over the world at the end of run 2022b
• Highest luminosity as a new record
• First turns and successful storage of beams in the SuperKEKB electron and positron rings

Introduction

Belle II is the B factory experiment upgraded from Belle as KEKB upgraded to SuperKEKB. It is designed to make precise measurements of weak interaction parameters and to probe new physics beyond the Standard Model. In June 2022, SuperKEKB achieved a new luminosity world record, 4.7×10³⁴ cm^-2s^-1. Up to now, 427.79 fb-1 data have been recorded in Belle II.
