Radiative Seesaw in Minimal 3-3-1 Model

TL;DR

This paper investigates a minimal 3-3-1 model where neutrino masses are generated radiatively at one-loop, linking them to charged lepton masses, and explores its compatibility with neutrino data, lepton flavor violation, and muon g-2.

Contribution

It introduces a minimal 3-3-1 model with radiative neutrino mass generation, establishing parameter regions consistent with experimental constraints.

Findings

Neutrino masses are generated at one-loop level linked to charged leptons.

Parameter space compatible with neutrino oscillation data and lepton flavor violation constraints.

Potential explanation for the muon anomalous magnetic moment.

Abstract

We study the neutrino sector in a minimal $SU(3)_L\times U(1)_X$ model, in which its mass is generated at one-loop level with the charged lepton mass, and hence there exists a strong correlation between the charged-lepton mass and the neutrino mass. We identify the parameter region of this model to satisfy the current neutrino oscillation data as well as the constraints on lepton flavor violating processes. We also discuss a possibility to explain the muon anomalous magnetic moment.
