TL;DR

This paper introduces a novel radiative mechanism for neutrino mass generation within the 3-3-1 gauge model, linking neutrino masses to gauge boson exchanges and predicting new particles accessible at colliders.

Contribution

It proposes a new neutrino mass generation mechanism in the 3-3-1 model with spontaneous lepton number breaking, connecting neutrino masses to gauge boson interactions.

Findings

Neutrino masses arise at one-loop level via neutral gauge boson exchange.

The model predicts new isosinglet neutrinos and quarks at the TeV scale.

Potential collider signatures include production of new gauge bosons and fermions.

Abstract

We propose a new radiative mechanism for neutrino mass generation based on the 3-3-1 electroweak gauge group. Lepton number is a symmetry of the Yukawa sector but spontaneously broken in the gauge sector. As a result light Majorana masses arise from neutral gauge boson exchange at the one-loop level. In addition to the isosinglet neutrinos which may be produced at the LHC through the extended gauge boson "portals", the model contains new isosinglet quarks which can also lie at the TeV scale and provide a plethora of collider phenomena.
