Description

In this talk I review the consequences of radiative flavour violation in the MSSM. Since self-energies can be chirally enhanced and therefore of order one it is possible to generate the light-quark masses and the CKM matrix via loops. In the case of CKM generation in the down-sector constraints from b->s gamma, and in the case of CKM generation in the up-sector from epsilon_K, are observed. In the second case the rare decay K-> pi nu nu receives sizable contributions while in the first case additional contributions to B_s->mu mu via neutral Higgs penguins occur. These Higgs penguins can also contribute to Bs mixing and are capable to explain the observed CP asymmetry. In conclusion I show that for SUSY masses around 1 TeV radiative flavour-violation is an interesting solution to the SUSY flavour and CP problem.
