Twin SIMPs

TL;DR

This paper demonstrates how embedding SIMPs into Twin Higgs models can simultaneously address the hierarchy problem and provide a viable dark matter candidate, linking their confinement scales naturally.

Contribution

It introduces a novel framework integrating SIMPs into Twin Higgs models, unifying solutions for dark matter and the hierarchy problem.

Findings

SIMP dark matter can be embedded in Twin Higgs models.

The model naturally explains the proximity of confinement scales.

The framework addresses both hierarchy problem and dark matter in a unified way.

Abstract

The hierarchy problem and the identity of dark matter are two of the central driving forces in particle physics. Twin Higgs models provide an elegant solution to the little hierarchy problem, while Strongly Interacting Massive Particles (SIMPs) provide an appealing dark matter candidate. Here we show that SIMPs can easily be embedded in the Twin Higgs setup, such that dark matter and the hierarchy problem can be addressed in a single framework. This also provides a natural explanation to the proximity between the confinement scale of SIMP dark matter and the strong scale of QCD.
