While the Standard Model (SM) describes flavour physics very accurately

The origin of flavour is one of the big, unsolved mysteries of fundamental physics!

While the Standard Model (SM) describes flavour physics very accurately, it does not explain its mysteries: Why are there 3 generations in nature? What determines the extreme hierarchy of fermion masses? What determines the extreme hierarchy of fermion masses? What determines the elements of the CKM matrix? What is the origin of the matter-antimatter asymmetry (CP violation)?

The SM CP-violation is insufficient to explain the matter/antimatter asymmetry progress in flavour physics may help understand open questions in cosmology

History has shown that flavour physics often gives first evidence for new discoveries: Kaon mixing, BR(K0

(neither at the intensity nor at the energy frontier) several “tensions” with the Standard Model have been resolved recently

but some discrepancies still around most recent and upcoming analysis of heavy flavour decays (in particular at most recent and upcoming analysis of heavy flavour decays (in particular at

LHC) are testing the Standard Model predictions to an unprecedented precision with future facilities (Belle II, Super B, LHCb upgrade) an ultimate precision
