Techni-composite Higgs models with symmetric and asymmetric dark matter candidates

We propose a novel class of composite models that feature both a technicolor and a composite Higgs vacuum limit, resulting in an asymmetric dark matter candidate. These techni-composite Higgs models are based on an extended left-right electroweak symmetry with a pseudo-Nambu Goldstone boson Higgs and stable dark matter candidates charged under a global U(1)X symmetry, connected to the baryon asymmetry at high temperatures via the SU(2)R sphaleron. We consider, as explicit examples, four-dimensional gauge theories with fermions charged under a new confining gauge group GHC.
