TL;DR

This paper proposes a novel gauge mechanism for neutrino mass generation involving a Goldstone boson mode and predicts a vector dark matter candidate, offering a unified approach to neutrino masses and dark matter stability.

Contribution

It introduces a scotogenic gauge mechanism where neutrino masses arise from gauge symmetry breaking and predicts a vector dark matter candidate stabilized by residual gauge symmetry.

Findings

Neutrino mass generated via a new gauge boson doublet.

Dark matter stability ensured by residual matter parity.

Predictive framework linking neutrino mass and dark matter.

Abstract

Scotogenic is a scheme for neutrino mass generation through the one-loop contribution of an inert scalar doublet and three sterile neutrinos. This work argues that such inert scalar doublet is a Goldstone boson mode associated with a gauge symmetry breaking. Hence, the resultant scotogenic gauge mechanism is very predictive, generating neutrino mass as contributed by a new gauge boson doublet that eats such Goldstone bosons. The dark matter stability is manifestly ensured by a matter parity as residual gauge symmetry for which a vector dark matter candidate is hinted.
