アブストラクト: We consider hidden sector technicolor models, assuming a hidden sector with vectorlike confining gauge theories like QCD. Then a scale \Lambda_H would be generated in the hidden sector by dimensional transmutation, and chiral symmetry breaking occurs in the hidden sector. Then this scale \Lambda_H can play a role of the SM Higgs mass parameter, triggering electroweak symmetry breaking (EWSB). Thus all the mass scales of the SM sector can arise from the hidden sector. Furthermore the lightest hadrons in the hidden sector is stable by the flavor conservation of the hidden sector strong interaction, could be the cold dark matter (CDM). We study collider phenomenology, and relic density and direct detection rates of the CDM of this model.
