Linkage of Dirac Neutrinos to Dark U(1) Gauge Symmetry

TL;DR

This paper proposes a mechanism connecting small Dirac neutrino masses with dark matter via an anomaly-free U(1) gauge symmetry involving fermion singlets.

Contribution

It introduces a novel framework linking neutrino mass generation to dark matter through a dark U(1) gauge symmetry.

Findings

Neutrino masses are naturally small within this model.

Dark matter candidates are incorporated via fermion singlets.

The model remains anomaly-free and consistent with gauge symmetry.

Abstract

It is shown how a mechanism which allows naturally small Dirac neutrino masses is linked to the existence of dark matter through an anomaly-free U(1) gauge symmetry of fermion singlets.
