Composite Higgs models, Dark Matter and Lambda

TL;DR

This paper proposes a model where dark matter is a stable composite fermion arising from holographic AdS/CFT frameworks, linking electroweak symmetry breaking to dark matter properties and addressing the cosmological constant problem.

Contribution

It introduces a novel composite fermion dark matter candidate within holographic models and connects Higgs physics to dark matter and cosmological constant issues.

Findings

Dark matter candidate X^0 has TeV-scale mass and satisfies cosmological bounds.

Holographic models provide a unified framework for Higgs and dark matter.

A discrete Higgs vacuum structure offers a new perspective on the cosmological constant.

Abstract

We suggest that dark matter can be identified with a stable composite fermion X^0, that arises within the holographic AdS/CFT models, where the Higgs boson emerges as a composite pseudo-goldstone boson. The predicted properties of X^0 satisfies the cosmological bounds, with m_X = O(TeV). Thus, through a deeper understanding of the mechanism of electroweak symmetry breaking, a resolution of the Dark Matter enigma is found. Furthermore, by proposing a discrete structure of the Higgs vacuum, one can get a distinct approach to the cosmological constant problem.
