Abstract

We discuss a specific model of extended GMSB type in which 5bar component of one messenger vector pair is treated as an extra flavour. FCNC effects related to the superpotential couplings between 5bar messenger and i-th family of MSSM matter, h_i, are analysed. We find that the strongest limit, h₁h₂<10^-3, emerges from constraints on RR slepton contribution to radiative muon decay. The results are in agreement with simple models of hierarchical Yukawa interactions.
