Phenomenology of fermion dark matter as neutrino mass mediator with gauged B-L

TL;DR

This paper explores a model where fermionic dark matter and neutrino masses are interconnected through a gauged B-L symmetry, predicting detectable signals in upcoming experiments.

Contribution

It introduces a novel B-L gauge symmetry framework that links neutrino mass generation with fermionic dark matter stability and predicts testable experimental signatures.

Findings

Dark matter masses and couplings are within reach of direct detection experiments.

Neutrinos are Dirac particles due to the model's symmetries.

The model successfully explains neutrino masses and dark matter relic abundance.

Abstract

We analyze a model with unbroken B-L gauge symmetry where neutrino masses are generated at one loop, after spontaneous breaking of a global U(1) symmetry. These symmetries ensure dark matter stability and the Diracness of neutrinos. Within this context, we examine fermionic dark matter. Consistency between the required neutrino mass and the observed relic abundance indicates dark matter masses and couplings within the reach of direct detection experiments.
