On Unitarity Based Relations Between Various Lepton Family Violating Processes

High Energy Physics - Phenomenology 2009-10-31 v1

Abstract

Simple "unitarity inspired" relations between two- and three-body lepton flavor violating decays are noted and discussed. In the absence of cancellations, the existing strong bounds on μ3e\mu \to 3e and μeγγ \mu\to e\gamma\gamma severly constrain two-body lepton flavor violating decays.
