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

We analyze a model with unbroken U(1)(B-L) gauge symmetry where neutrino masses are generated at one loop, after spontaneous breaking of a global U(1)(G) symmetry. These symmetries ensure dark matter (DM) 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. (C) 2021 The Author(s).

Automated summary

In this analysis, a model with unbroken U(1)(B-L) gauge symmetry is examined, where neutrino masses are generated after spontaneous breaking of a global U(1)(G) symmetry. The study focuses on fermionic dark matter and indicates that dark matter masses and couplings are within the reach of direct detection experiments based on consistency with required neutrino mass and observed relic abundance.
