28. Critical Role of the B factories in the verification of the KM hypothesis was recognized and cited by the Nobel Foundation A single irreducible phase in the weak interaction matrix accounts for most of the CPV observed in kaons and B’s. CP violating effects in the B sector are O(1) rather than O(10 -3 ) as in the kaon system. 2008: 28
