Most of the traditional Technicolor-based models are known to be in a strongtension with the electroweak precision tests. We show that this serious issueis naturally cured in strongly coupled sectors with chiral-symmetricvector-like gauge interactions in the framework of gauged linear \sigma-model.We discuss possible phenomenological implications of such non-standardchiral-symmetric Technicolor scenario in its simplest formulation preservingthe Standard Model (SM) Higgs mechanism. For this purpose, we assume theexistence of an extra technifermion sector confined under extra SU(3)_TC at theenergy scales reachable at the LHC, \Lambda_TC ~ 0.1-1 TeV, and interactingwith the SM gauge bosons in a chiral-symmetric (vector-like) way. In theframework of this scenario, the SM Higgs vev acquires natural interpretation interms of the condensate of technifermions in confinement in the nearlyconformal limit. We study the influence of the lowest lying composite physicalstates, namely, technipions, technisigma and constituent technifermions, on theHiggs sector properties in the SM and other observables at the LHC. We foundout that the predicted Higgs boson signal strengths in \gamma\gamma,vector-boson VV* and fermion ffbar decay channels can be sensitive to the newstrongly-coupled dynamics and are consistent with the current SM-like Higgsboson observations in the limit of relatively small Higgs-technisigma mixing.At the same time, the chiral-symmetric Technicolor provides us with richtechnipion phenomenology at the LHC, and its major implications are discussedin detail.
