Testing the gauged $\mathrm{U(1)}_{B-L}$ model for loop induced neutrino mass with dark matter

TL;DR

This paper proposes a new model where neutrino masses are generated radiatively through dark sector particles, including dark matter, with spontaneous U(1)_{B-L} symmetry breaking, and discusses its testability at colliders.

Contribution

It introduces a benchmark scenario for a U(1)_{B-L} model explaining neutrino masses and dark matter, consistent with current data and testable at colliders.

Findings

Identified benchmark points satisfying experimental constraints.

Neutrino masses generated radiatively via dark sector particles.

Abstract

We present a new viable benchmark scenario under the current experimental data for the model which can explain tiny mass of active neutrinos and dark matter, as a summary of our results. Majorana masses of right-handed neutrinos are given by the spontaneous breaking of the $\mathrm{U(1)}_{B-L}$ gauge symmetry above the electroweak scale, and tiny neutrino masses are radiatively induced by quantum effects of particles of the dark sector including dark matter candidates. We first show benchmark points which satisfy current experimental data, and then give comments on how this model can be tested at collider experiments.
