The Belle II experiment is a particle physics experiment designed to study the properties of B mesons (heavy particles containing a bottom quark) and other particles. Belle II is the successor to the Belle experiment, and commissioned at the SuperKEKB[1] accelerator complex at KEK in Tsukuba, Ibaraki prefecture, Japan. The Belle II detector was "rolled in" (moved into the collision point of SuperKEKB) in April 2017.[2][3] Belle II started taking data in early 2018.[1] Over its running period, Belle II is expected to collect around 50 times more data than its predecessor, mostly due to a 40-fold increase in an instantaneous luminosity provided by SuperKEKB as compared to the previous KEKB accelerator.[1]
