B -> phi KS CP asymmetries as a probe of supersymmetry
Abstract
We consider sparticle contributions to time dependent CP asymmetry in B -> phi KS. As for the gluino-squark loop, LR or RL insertion is more likely to give recently observed Sphi K < 0 than LL or RR insertion. Neutral Higgs contribution does not change Sphi K very much due to the strong constraint from Bs -> mu+ mu-. We also show correlations among related processes such as direct CP asymmetry in B -> Xs gamma and Bs - Bs bar mixing, and discuss theoretical motivations for desired strength of flavor violation.
