Contribution

It introduces a novel two-loop neutrino mass generation mechanism within a gauged lepton symmetry, predicting a massless neutrino and incorporating dark matter.

Findings

Neutrino masses are generated at two-loop level.

Predicts one massless active neutrino.

Includes a viable dark matter candidate.

Abstract

We study a neutrino model introducing an additional nontrivial gauged lepton symmetry where the neutrino masses are induced at two-loop level while the first and second charged-leptons of the standard model are done at one-loop level. As a result of model structure, we can predict one massless active neutrino, and there is a dark matter candidate. Then we discuss neutrino mass matrix, muon anomalous magnetic moment, lepton flavor violations, oblique parameters, and relic density of dark matter taking into account the experimental constraints.
