Accidental stability of dark matter

TL;DR

This paper proposes a novel mechanism for dark matter stability based on an accidental Z2 symmetry derived from a flavor symmetry group related to geometric solids, with phenomenology similar to Higgs portal models.

Contribution

It introduces a new theoretical framework linking dark matter stability to geometric symmetry groups, expanding the understanding of possible symmetry origins.

Findings

Dark matter stability can arise from geometric symmetry groups.

Phenomenology aligns with Higgs portal dark matter models.

Provides a model-dependent but innovative approach to dark matter stability.

Abstract

We propose that dark matter is stable as a consequence of an accidental Z2 that results from a flavour-symmetry group which is the double-cover group of the symmetry group of one of the regular geometric solids. Although model-dependent, the phenomenology resembles that of a generic Higgs portal dark matter scheme.
