Scalar flavour changing neutral currents in MFV SUSY at large tanβ

We discuss the origin and phenomenological consequences of the flavour violating couplings of the neutral Higgs bosons to the down-type quarks generated in the minimal supersymmetric standard model (MSSM) for large values of tan beta. We concentrate on the scenario with minimal flavour and CP violation (MFV) and demonstrate the tight correlation of the B-s(0)-(B) over bar (0)(s) mass difference with BR(B-s(0) --> mu(+)mu(-)) and BR(Bd0 --> mu(+)mu(-)). While the first correlation holds also in the case of non-minimal flavour violation, the second one is specific for the minimal case and can potentially serve as a test of the sources of flavour violation in supersymmetry.
