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 $μ\to eγ$ decay and $μ- e$ - conversion place significant constraints on relevant coupling constants. On the other hand, the rates of $τ\to eγ$ and $τ\to μγ$ in MGMM are well below the existing limits. We also point out the possibility of sizeable slepton oscillations in this model.
