Abstract

A model is presented where the electron and muon masses are radiative and depend, respectively, on the masses of $τ$ and a fourth charged lepton $E$ . A discrete $Z_{4}$ symmetry is softly broken down to $Z_{2}$ which distinguishes ( $μ$ , $τ$ ) from ( $e$ , $E$ ). All three known neutrinos acquire radiative Majorana masses.
