Minimal flavor violation and the scale of supersymmetry breaking.
In this paper we explore the constraints from B-physics observables in supersymmetric models of minimal flavor violation, in the large tan-{beta} regime, for both low and high-scale supersymmetry breaking scenarios. We find that the rare B-decays b {yields} s{gamma} and B{sub s} {yields} {mu}{sup +}{mu}{sup -} can be quite sensitive to the scale M at which supersymmetry breaking is communicated to the visible sector. In the case of high scale supersymmetry breaking, we show that the additional gluino contribution to the b {yields} s{gamma} and B{sub s} {yields} {mu}{sup +}{mu}{sup -} rare decay rates can be significant for large tan-{beta}, {mu} and M{sub 3}. The constraints on B{sub u} {yields} {tau}{nu} are relatively insensitive to the precise scale of M. We also consider the additional constraints from the present direct Higgs searches at the Tevatron in the inclusive H/A {yields} {tau}{tau} channel, and the latest Cryogenic Dark Matter Search direct dark matter detection experiments. We find that altogether the constraints from B-physics, Higgs physics, and direct dark matter searches can be extremely powerful in probing regions of supersymmetric parameter space for low MA and large tan-{beta}, leading to a preference for models with a lightest CP-even Higgs mass close to the current experimental limit. We find interesting regions of parameter space that satisfy all constraints and can be probed by Higgs searches at the Tevatron and the LHC and by direct dark matter searches in the near future.
