In this article we investigate the consequences of radiative flavor violation(RFV) in the Minimal Supersymmetric Standard Model (MSSM). In this frameworkthe small off-diagonal elements of the Cabibbo-Kobayashi-Maskawa (CKM) matrixand the small quark masses of the first two generations are generated from thetrilinear supersymmetry-breaking terms. The impact of RFV on flavor-physicsobservables is studied in detail. We focus on the limiting cases in which theCKM matrix is either generated in the down-sector, i.e. by the softSUSY-breaking mass insertions delta^dLR_i3 (i=1,2), or in the up-quark sector,i.e. by the mass insertions delta^uLR_i3. In the first case we find anenhancement of b->s gamma, which constrains the allowed range of sparticlemasses (Fig. 3). In addition, neutral Higgs penguins significantly contributeto B_s,d->mu^+mu^- and, if also delta^dLR_32 is different from zero, theseHiggs effects are capable of explaining the observed CP phase in the B_ssystem. If, on the other hand, the CKM generation takes place in the up-sector,|epsilon_K| receives additional positive contributions enforcing large squarkand gluino masses (see Fig. 8). In this case also the rare decay K->pi nu nureceives sizable contributions. In conclusion we find that for SUSY massesaround 1 TeV RFV is an interesting alternative to Minimal Flavor Violation(MFV).
