Dark $SU(2) \to Z_3 \times Z_2$ Gauge Symmetry

TL;DR

This paper explores a dark sector with an $SU(2)$ gauge symmetry that breaks down to a $Z_3 imes Z_2$ symmetry, analyzing its implications for dark matter phenomenology.

Contribution

It introduces a novel symmetry breaking pattern from $SU(2)$ to $Z_3 imes Z_2$ and studies its effects on dark matter properties.

Findings

Dark matter stability is linked to the residual $Z_3 imes Z_2$ symmetry.

The symmetry breaking pattern affects dark matter interactions and relic abundance.

New phenomenological signatures are proposed for this gauge symmetry structure.

Abstract

The dark sector is postulated to be invariant under an $SU(2)$ gauge symmetry, spontaneously broken by a Higgs quadruplet to a conserved residual $Z_3 \times Z_2$ symmetry. The resulting dark matter phenomenology is studied.
