Higgs-Flavor Groups, Naturalness, and Dark Matter

TL;DR

This paper explores how non-abelian symmetries among multiple Higgs doublets can address naturalness issues and predict stable particles that could serve as dark matter candidates, with testable mass relations.

Contribution

It introduces a framework where Higgs flavor groups explain naturalness and predict stable dark matter particles through non-abelian symmetries.

Findings

Multiple Higgs doublets can be stabilized by non-abelian symmetries.

Remnants of these symmetries lead to testable Higgs mass relations.

Stable Higgs particles can serve as dark matter candidates.

Abstract

In the absence of low-energy supersymmetry, a multiplicity of weak-scale Higgs doublets would require additional fine-tunings unless they formed an irreducible multiplet of a non-abelian symmetry. Remnants of such symmetry typically render some Higgs fields stable, giving several dark matter particles of various masses. The non-abelian symmetry also typically gives simple, testable mass relations.
