Lepton-flavor violating decays as probes of quantum gravity?

Abstract

Lepton flavor violating decays $Z\to \mu \tau$ and $J/\Psi ,{\rm Y}\to \mu \tau$ are considered. It is shown that these decays can reach sizeable magnitudes if some specific lepton-flavor violating 4-fermion operators are generated by low scale quantum gravity effects, or by some other new physics at a TeV scale.
