What is Chiral-Symmetric Technicolor with Standard Model Higgs boson about?

Most of the traditional Technicolor-based models are known to be in a strong tension with the electroweak precision tests. We show that this serious issue is naturally cured in strongly coupled sectors with chiral-symmetric vector-like gauge interactions in the framework of gauged linear \sigma-model. We discuss possible phenomenological implications of such non-standard chiral-symmetric Technicolor scenario in its simplest formulation preserving the Standard Model (SM) Higgs mechanism. For this purpose, we assume the existence of an extra technifermion sector confined under extra SU(3)_TC at the energy scales reachable at the LHC, \Lambda_TC ~ 0.1-1 TeV, and interacting with the SM gauge bosons in a chiral-symmetric (vector-like) way. In the framework of this scenario, the SM Higgs vev acquires natural interpretation in terms of the condensate of technifermions in confinement in the nearly conformal limit. We study the influence of the lowest lying composite physical states, namely, technipions, technisigma and constituent technifermions, on the Higgs sector properties in the SM and other observables at the LHC. We found out that the predicted Higgs boson signal strengths in \gamm
