The Belle II experiment is the only particle physics experiment taking data at an asymmetric electron-positron collider in order to study flavour physics and in particular the properties of B mesons (particles containing a b quark). Belle II takes data at the SuperKEKB accelerator at KEK, in Tsukuba, Japan. In June 2022, SuperKEKB achieved a new luminosity world record of 4.7x1034cm−2s−1. From 2019-2022 Belle II accumulated a 400 fb-1 data sample. These data provide large samples of beauty and charm hadrons, as well as tau leptons. Unique searches for dark-matter related particles are also pursued.
Prof. Bevan and Dr Bona from PPRC at QMUL have joined the Belle II collaboration in November 2023.
