Composite Higgs models, Dark Matter and Lambda
Abstract
We suggest that dark matter can be identified with a stable composite fermion X0, that arises within the holographic AdS/CFT models, where the Higgs boson emerges as a composite pseudo-goldstone boson. The predicted properties of X0 satisfies the cosmological bounds, with mX = 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.
