We study the implications of minimal flavor violating low energy supersymmetry
scenarios for the search of new physics in the B and Higgs sectors at the Tevatron
collider and the LHC. We show that the already stringent Tevatron bound on the
decay rate Bs -* p+ - sets strong constraints on the possibility of generating large
corrections to the mass difference AM, of the B, eigenstates. We also show that
the Bs -* p+ - bound together with the constraint on the branching ratio of the
rare decay b -* sy has strong implications for the search of light, non-standard Higgs
bosons at hadron colliders. In doing this, we demonstrate that the former expressions
derived for the analysis of the double penguin contributions in the Kaon sector need
to be corrected by additional terms for a realistic analysis of these effects. We also
study a specific non-minimal flavor violating scenario, where there are flavor changing
gluino-squark-quark interactions, governed by the CKM matrix elements, and show
that the B and Higgs physics constraints are similar to the ones in the minimal flavor
violating case. Finally we show that, in scenarios like electroweak baryogenesis which
have light stops and charginos, there may be enhanced effects on the B and K mixing
parameters, without any significant effect on the rate of Bs -* [ p-
