Abstract
With the discovery of neutrino masses, it is clear that lepton‐flavor is no longer a conserved quantity. This means that charged‐lepton flavor violating processes (CLFV) including rare muon and tau decays (e.g. μ → eγ, τ → μe+e−) are, in principle, observable. I review some phenomenological aspects of CLFV (concentrating on rare muon processes) and briefly discuss a few Standard Model extensions that predict a “large” rate for CLFV. In several of these extensions there are deep relations between the physics that generates neutrino masses and mixing and CLFV.
