Muon and Electron Number Nonconservation in aV−AGauge Model

We analyze muon and electron lepton-number nonconservation in a pure $V-A$ gauge model. The rates for $\mu \to e\gamma$, $\mu \to \mathrm{ee}\overline{e}$, and $K_L\to \mu \overline{e}$ are computed for this model. We find that for a reasonable range of neutral heavy-lepton mass these rates are in accord with, but not extremely small compared to, present experimental bounds. We comment on the nonorthogonality of ${\nu }_e$ and ${\nu }_{\mu }$, and interesting features of the $L^{-}$ decays.
