Exotic decays of the muon and heavy leptons in gauge theories
Abstract
We have studied the decay ℓ 1 → ℓ 2 + γ for arbitrary like charged spin {1}/{2} leptons in a manner which is applicable to a large class of models. Our computations assume that this process is induced by one loop diagrams. When the leading effect is cancelled by a leptonic G.I.M. mechanism, we find an extremely large enhancement of O( MW4/ ML4) in Λ( μ-→ e-+ e+e-)/ Λ( μ-→ e-+ γ) if the intermediate lepton is charged.
