Messenger-matter mixing and lepton flavor violation

Abstract

We consider the Minimal Gauge Mediated Model (MGMM) with messenger-matter mixing and find that existing experimental limits on $\mu \to e\gamma$ decay and $\mu -e$ - conversion place significant constraints on relevant coupling constants. On the other hand, the rates of $\tau \to e\gamma$ and $\tau \to \mu \gamma$ in MGMM are well below the existing limits. We also point out the possibility of sizeable slepton oscillations in this model.
