One-Loop Electron Mass and Three-Loop Dirac Neutrino Masses

Abstract

In the context of a left-right extension of the standard model of quarks and leptons with the addition of a gauged $U(1{)}_D$ dark symmetry, it is shown how the electron may obtain a radiative mass in one loop and two Dirac neutrinos obtain masses in three loops.
