SuperKEKB Project - SuperKEKB

The SuperKEKB project is our response to the challenge of solving Nature’s fundamental puzzles by upgrading the KEKB electron-positron collider and the Belle detector. The KEKB accelerator and the Belle detector demonstrated the violation of CP asymmetry proposed by Dr. Makoto Kobayashi and Dr. Toshihide Maskawa, who received the 2008 Nobel Prize in Physics. The KEKB collider has been a leader in the race to provide the world’s highest luminosity. The next target is 40 times greater than KEKB’s record by the upgrade to SuperKEKB and Belle II. The target luminosity is 8×10³⁵ cm^-2s^-1 and this improvement allows us to discover new physics beyond the Standard Model.
