Status and prospects of the Belle II experiment

Abstract

Measurements using the Belle detector at the KEKB collider in Japan have achieved important progress in the flavor structure of the Standard Model of elementary particle physics. Both the collider and the detector are being upgraded to the SuperKEKB collider and the Belle II detector to collect about 40 times higher luminosity of the Belle experiment with several improvements in the detector performance. Using the higher statistics, several measurements with precision comparisons to the predictions in the Standard Model will be performed to search for new physics beyond the Standard Model from a wide range of flavor physics channels. This paper describes the physics prospects and collider/detector construction status of the Belle II experiments.
