Description

In a SUSY GUT seesaw scenario, the largeness of the atmospheric neutrino mixing can reflect itself into an enhanced flavor changing mixing of beauty and strange right-handed scalar quarks. If the CP violating phase in such down-type squark RR insertion is the main source of CP asymmetry in Bd→φKS and the gluino contributions to K0-K0 and B0-B0 mixing are negligible, there is a correlation between Re (ε'/εK) and Bd→φKS CP asymmetry, in addition to that with the strange quark CEDM. The current data on Re (ε'/εK)=(16.7±2.6)x10-4 imply that SφK should be greater than ∼0.5(0.25) for μtanβ=1(5) TeV, assuming the RR dominance in b→s transition and the minimal supergravity type boundary conditions for soft parameters
