We study the implications of minimal flavor violating low energy supersymmetryscenarios for the search of new physics in the B and Higgs sectors at the Tevatroncollider and the LHC. We show that the already stringent Tevatron bound on thedecay rate Bs -> mu+mu- sets strong constraints on the possibility of generating largecorrections to the mass difference
Ms of the Bs eigenstates. We also show thatthe Bs -> mu+mu- bound together with the constraint on the branching ratio of therare decay b -> s gamma has strong implications for the search of light, non-standard Higgsbosons at hadron colliders. In doing this, we demonstrate that the former expressionsderived for the analysis of the double penguin contributions in the Kaon sector needto be corrected by additional terms for a realistic analysis of these effects. We alsostudy a specific non-minimal flavor violating scenario, where there are flavor changinggluino-squark-quark interactions, governed by the CKM matrix elements, and showthat the B and Higgs physics constraints are similar to the ones in the minimal flavorviolating case. Finally we show that, in scenarios like electroweak baryogenesis whichhave light stops and charginos, there may be enhanced effects on the B and K mixingparameters, without any significant effect on the rate of Bs -> mu+mu- .
