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.

Summary
The hierarchy problem between the electroweak scale and higher energy scales is one of the most pressing problems in particle physics. The discovery of the Higgs boson at the Large Hadron Collider (LHC) in 2012 along with the lack of experimental evidence for new weak-scale particles highlights this problem further. [2,3,4,5,6,7,8,9].) twin Higgs models (and other theories of neutral naturalness) contain a QCD-like sector, similar to QCD of the SM but not identical to it. We show that this can be done, obtaining a natural theory with strongly self-interacting sub-GeV dark matter while addressing the hierarchy problem. Higgs solution to the hierarchy problems requires the twin QCD coupling and scale—namely the SIMP sector in the framework presented here—to be similar to that of the QCD sector itself
