The Belle II Experiment at KEK is an international collaboration of scientists from around the world who are working together to study the properties of particles and forces that make up our universe. The experiment is located at the KEK laboratory in Tsukuba, Japan, and is the successor to the original Belle
The Belle II experiment is a particle physics experiment designed to study the properties of B mesons and other particles. Belle II is the successor to the Belle experiment, and commissioned at the SuperKEKB accelerator complex at KEK in Tsukuba, Ibaraki prefecture, Japan. The Belle II detector was "rolled in" in April 2017. Belle II started taking data in early 2018. 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.
