Abstract
The Belle II experiment at the SuperKEKB energy asymmetric e+e−collider is a substantial upgrade of the B factory facility at the Japanese KEK laboratory. The design luminosity of the machine is 6×10^35 cm^{−2} s^{−1} and the Belle II experiment aims to record 50ab^{−1]of data, a factor of 50 more than its predecessor. With this data set, Belle II will be able to measure the Cabibbo-Kobayashi-Maskawa (CKM) matrix, the matrix elements and their phases, with unprecedented precision and explore flavor physics with B, charmed mesons, and tau leptons. Belle II has also a unique capability to search for low-mass dark matter and low-mass mediators. In this paper, we will review the status of the Belle II detector, SuperKEKB accelerator and the prospects for physics at Belle II.
Author comments upon resubmission
point 1: question asked by referee: Provide a brief estimate as to when the Belle II experiment will complete data taking.
Ans (point 1): Belle II has been running continuously and collecting data despite the Covid-19 pandemic.
Long Shut Down 1 is expected to start this year in July and it will continue till 15 months. By this time we are expected to collect about 500fb^{-1} of data. Further, its aim is to record data at an integrated luminosity of 50 ab^{−1}
