TL;DR

This paper introduces an extended 3-3-1 gauge model that incorporates a radiative linear seesaw mechanism, successfully explaining neutrino masses and the muon g-2 anomaly within experimental bounds.

Contribution

It presents a novel implementation of a one-loop linear seesaw mechanism in a 3-3-1 model without requiring a scalar sextet, addressing neutrino masses and muon g-2 simultaneously.

Findings

Successfully explains active neutrino masses

Reproduces the muon g-2 anomaly

Compatible with existing experimental bounds

Abstract

Motivated by the recent muon anomalous magnetic moment (g-2) measurement at FERMILAB and non-zero neutrino masses, we propose a model based on the $SU(3)_C \times SU(3)_L \times U(1)_X$ (3-3-1) gauge symmetry. The most popular 3-3-1 models in the literature require the presence of a scalar sextet to address neutrino masses. In our work, we show that we can successfully implement an one-loop linear seesaw mechanism with right-handed neutrinos, and vector-like fermions to nicely explain the active neutrino masses, and additionally reproduce the recent Muon g-2 result, in agreement with existing bounds.
