Abstract

We present an updated phenomenological analysis of the minimal flavor violating (MFV) effective theory, both at small and large tan beta, in the sector of Delta F=1 processes. We evaluate the bounds on the scale of new physics derived from recent measurements (in particular from B to Xs gamma, B to Xs l+ l-, Bs to mu+ mu- and K to pi nu bar nu) and we use such bounds to derive a series of model-independent predictions within MFV for future experimental searches in the flavor sector.
