Neutrinoless double beta decay and lepton flavor violation

Extensions of the Standard Model with low scale (∼TeV) lepton number violation generally lead to a pattern of lepton flavor violation experimentally distinguishable from the one implied by models with GUT scale lepton number violation. Therefore, muon lepton flavor violation processes provide a diagnostic tool to determine whether or not the effective neutrino mass can be deduced from the rate of neutrinoless double beta decay.
