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

TL;DR

This paper explores a left-right extension of the standard model with a dark symmetry, demonstrating how electrons and neutrinos can acquire masses through radiative loop processes, with electrons at one loop and neutrinos at three loops.

Contribution

It introduces a novel model where electron and neutrino masses are generated radiatively via loop processes in a left-right symmetric framework with a dark gauge symmetry.

Findings

Electron mass generated at one loop.

Neutrino masses generated at three loops.

Consistent with observed particle 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.
