Neutrino masses and lepton-flavor violation in a supersymmetric model with lopsided Froggatt–Nielsen charges

We analyze in detail lepton-flavor violation (LFV) in the charged-lepton sector, such as μ→eγ and τ→μγ within the framework of supersymmetric models with lopsided Froggatt–Nielsen charges. We show that the present experimental limits on the LFV processes already exclude some of the models. The proposed future search for LFV, especially in muon processes, can provide a significant probe to this framework.
