Neutrino Mass and Dark Matter from Gauged B$-$L Breaking

TL;DR

This paper proposes a new radiative seesaw model with gauged B-L symmetry broken at the TeV scale, explaining dark matter and tiny neutrino masses simultaneously with minimal fermion content.

Contribution

It introduces an improved anomaly-free radiative seesaw model with gauged B-L symmetry, reducing fermion content while explaining neutrino masses and dark matter.

Findings

Dark matter and neutrino masses are explained within the model.

The model operates with B-L symmetry breaking at the TeV scale.

It maintains anomaly cancellation with minimal fermions.

Abstract

We discuss a new radiative seesaw model with the gauged B$-$L symmetry which is spontaneously broken. We improve the previous model by using the anomaly-free condition without introducing too many fermions. In our model, dark matter, tiny neutrino masses and neutrino oscillation data can be explained simultaneously, assuming the B$-$L symmetry breaking at the TeV scale.
