摘要:	We consider a hidden sector with a vectorlike confining gauge theory like QCD with N(h,c) colors and N(h,f) light quarks Q(h) in the hidden sector. Then a scale Lambda(H) would be generated by dimensional transmutation, and chiral symmetry breaking occurs in the hidden sector. This scale Lambda(H) can play a role of the SM Higgs mass parameter, triggering electroweak symmetry breaking (EWSB). Furthermore the lightest mesons in the hidden sector is stable by flavor conservation of the hidden sector strong interaction, and could be a good cold dark matter (CDM). We study collider phenomenology, and relic density and direct detection rates of the CDM of this model. (C) 2010 Elsevier B.V. All rights reserved.
