Description

Recent experimental results such as the D0 measurement of the dimuon asymmetry in B_s decays hint at a flavor structure beyond that of the standard CKM mechanism. This development puts the supersymmetric flavor problem back on the agenda. I discuss an alternative to the widely studied minimally flavor violating MSSM, which cannot explain a large CP phase in B_s mixing: The smallness of the Yukawa couplings of the first two generations suggests the idea that these coupling might be induced by radiative corrections. This is possible within the MSSM where sfermion-gaugino loops involving the trilinear A-terms can generate the desired effective couplings. While this model of radiative flavour violation can solve the SUSY CP and flavour problems, it is not completely minimally flavor-violating. I discuss the phenomenological consequences of this model in the quark sector. Strong constraints come from Kaon mixing or b->s gamma and measurable effects in the rare Kaon decay K->pi nu nu are expected.
