Description
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 goal of the experiment is to exceed the integrated luminosity of 50 ab^-1, which is roughly 50 times larger than the Belle dataset. With this data set, Belle II will be able to measure the Cabibbo-Kobayashi-Maskawa (CKM) matrix, the matrix elements and their phases with high precision and explore flavor physics with B and charmed mesons, and τ leptons. In this presentation, we will review the status of the Belle II detector operation, the recent physics results with the initial data, and prospects for the Belle II physics.
