First data and prospects of the Belle II experiment

by Isabelle Ripp-Baudot (IPHC, CNRS/IN2P3)


After its commissioning in 2018, the Belle II experiment has started registering first physics data delivered by the SuperKEKB e+e- collider in 2019. The Belle II physics program focuses on the search for physics beyond the standard model with precise measurements in the heavy quark and lepton sector. The huge targeted dataset of 50 ab-1 and the B-factory particular collision scheme will help to significantly improve the experimental precision on many flavour measurements. We will report on the start of the experiment and on performances observed with the very first data, and present prospects with the increasing dataset.
