Abstract

We derive constraints on the mass insertion parameters from the recent measurements of $B_{s} - {\bar{B}}_{s}$ mixing, and discuss their implications on SUSY breaking mediation mechanisms and SUSY flavor models. Some SUSY flavor models are already excluded or disfavored by $B_{s} - {\bar{B}}_{s}$ mixing. We also discuss how to test the SM and SUSY models in the future experiments, by studying other $C P$ violating observables related to $b \to s$ transition, such as the time-dependent $C P$ asymmetry in $B_{d} \to ϕ K_{S}$ and the direct $C P$ asymmetry in $B \to X_{s} γ$ .
