Lepton-flavor violation with non-universal soft terms

We study the lepton-flavor violation processes tau --> mu gamma and mu --> e gamma in two different examples of models with non-universal soft breakin g terms derived from strings. We show that the predictions are quite differ ent from those of universal scenarios. Non-universal A-terms provide an int eresting framework to enhance the supersymmetric contributions to CP violat ion effects. We observe that in the case of the lepton-flavor violation we study, the non-universality of the scalar masses enhances the branching rat ios more significantly than the non-universality of the A-terms. We find th at the current experimental bounds on these processes restrict both the par ameter space of the models and the texture of the Yukawa couplings which pr edicts the lepton masses, providing at the same time an interesting experim ental test for physics beyond the Standard Model.
