Description

We apply the effective field theory definition of Minimal Flavour Violation (MFV) to the MSSM, requiring the squark soft terms to become functions of the SM Yukawa couplings. For the case of meson oscillations in the DB=2 sector, we show that this approach leads to a striking increase of the predictivity of the model. In particular, we find (i) SUSY corrections to be naturally small and always positive (ii) if mu is not small, an increase in importance (even for low tan beta) of scalar operators due to gluino contributions. The last point signals that (V-A) x (V-A) dominated MFV is in general inconsistent with the MSSM. In this context, we also briefly discuss the MFV-Unitarity Triangle.
