Belle II experiment

[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.

The physics program of Belle II includes the studies of the following particles or processes:[7] The majority of the Belle II dataset will be recorded at Upsilon(4S) center-of-mass energy, while a small portion of it will be taken at Upsilon(5S) and as energy scans.

Belle II is a general purpose high-energy particle detector with almost full solid angle coverage.

Much of the original Belle detector has been upgraded[4] to cope with the higher instantaneous luminosity provided by the SuperKEKB accelerator.

[17] On 15 June 2020, the SuperKEKB reached an instantaneous luminosity of 2.22×1034 cm−2s−1 — surpassing the LHC's record of 2.14×1034 cm−2s−1 set with proton–proton collisions in 2018.
