SuperKEKB is an upgrade project at KEK (Tsukuba, Japan) to increase the instantaneous luminosity until 6×1035 cm–2 s–1. The next-generation B-factory, Belle II (successor of Belle), will complement the exploration of New Physics beyond the Standard Model currently being carried out at the energy frontier by the experiments at the Large Hadron Collider (LHC). While the LHC experiments provide a direct probe of the TeV mass scale, high-precision measurements of rare decays and CP-violation in heavy quarks and leptons provide a unique probe of New Physics at these and even higher mass scales through the effects of new particles in higher order processes.
