On Unitarity Based Relations Between Various Lepton Family Violating Processes

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 $\mu \to 3e$ and $\mu \to e\gamma \gamma$ severly constrain two-body lepton flavor violating decays.
