Lepton flavor violation in muonium decay and muon colliders in models with heavy neutrinos

Gorazd Cvetic, Claudio O. Dib, Choong-Sun Kim +1

We study the lepton-flavor-violating reaction ${\mu }^{+}{e}^{-}\to e^{+}{e}^{-}$ within two extensions of the standard model that include heavy neutrinos. The reaction is studied in the low ene…
