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.
