Abstract

We derive the effective action for composite Higgs models in electroweak theory from Nambu-Jona-Lasinio model. This action contains vector and axial vector mesons together with Higgs, W, Z and photon. Due to the interaction of the techni-quark with SU(2) L × U(1) gauge fields, mixing terms of SU(2) L × U(1) gauge fields and vector and axial vector resonances develop in the kinetic term of the effective action. Mass relation of the techni-rho and the Higgs is obtained.
