The Lepton Flavor Violating (LFV) processes μ→eγ and τ→μγ are estimated in a model of electroweak-scale right-handed neutrinos. The present bounds on the branching ratios, B(μ→eγ)<1.2×10−11, B(τ→μγ)<6.8×10−8 (BaBar) and <4.5×10−8 (Belle), put strong constraints on the parameters of the model. This constraint links low energy rare decay processes to high-energy phenomena (e.g., decay lengths of the mirror charged leptons which are important in the search for the telltale like-sign dilepton events present in the model of electroweak-scale right-handed neutrinos). The model can be tested at future colliders (LHC, ILC) and at MEG and/or B factories.
