The belle II experiment: Status and prospects

This article aims to describe the Belle II experiment, its status and physics prospects for the next several years. Belle II is situated in Japan, at the KEK laboratory and it is the upgraded version of the Belle experiment. It uses a new collider named SuperKEKB, a second generation of B-factory based on the innovative Nano-Beam scheme technique, which is expected to collect an integrated luminosity of 50 ab-1. Using this amount of data, together with improved detector performances, it will be possible to provide important contributions about several flavour physics topics (i.e. CKM matrix elements, FCNC processes, quarkonium states etc..) through high precision measurements. The main aim of Belle II is to investigate new physics scenarios and validate highly suppressed SM predictions. The experiment is almost completely assembled; it already took the first data without the vertex detector installed while the data taking will start in February 2019.
