TL;DR

This paper explores a dark matter model stabilized by a Z2 parity derived from an A4 flavor symmetry, linking neutrino mixing patterns with dark matter stability and analyzing its experimental detectability.

Contribution

It introduces a novel A4-based model where dark matter stability arises from flavor symmetry breaking, connecting neutrino physics with dark matter phenomenology.

Findings

Identifies parameter space consistent with relic density and experimental constraints.

Predicts potential signals for direct and indirect dark matter detection.

Shows compatibility with electroweak precision tests and collider bounds.

Abstract

We investigate a model in which Dark Matter is stabilized by means of a Z2 parity that results from the same non-abelian discrete flavor symmetry which accounts for the observed pattern of neutrino mixing. In our A4 example the standard model is extended by three extra Higgs doublets and the Z2 parity emerges as a remnant of the spontaneous breaking of A4 after electroweak symmetry breaking. We perform an analysis of the parameter space of the model consistent with electroweak precision tests, collider searches and perturbativity. We determine the regions compatible with the observed relic dark matter density and we present prospects for detection in direct as well as indirect Dark Matter search experiments.
