Abstract

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 (ǫ ′ /ǫK) and Bd → φKS CP asymmetry, in addition to that with the strange quark CEDM. The current data on Re (ǫ ′ /ǫK) = (16.7 ± 2.6) × 10−4 imply that SK should be greater than ∼ 0.5 (0.25) for μ tan β = 1 (5) TeV, assuming the RR dominance in b → s transition and the minimal supergravity type boundary conditions for soft parameters.
