  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 \gamma\gamma,
vector-boson VV* and fermion ffbar decay channels can be sensitive to the new
strongly-coupled dynamics and are consistent with the current SM-like Higgs
boson observations in the limit of relatively small Higgs-technisigma mixing.
At the same time, the chiral-symmetric Technicolor provides us with rich
technipion phenomenology at the LHC, and its major implications are discussed
in detail.
