  We expand the previous analyses of the conformal barrier on the walking
technirho for the 2 TeV diboson excesses reported by the ATLAS collaboration,
with a special emphasis on the hidden local symmetry (HLS) constraints. We
first show that the Standard Model (SM) Higgs Lagrangian is equivalent to the
scale-invariant nonlinear chiral Lagrangian, which is further gauge equivalent
to the scale-invariant HLS model, with the scale symmetry realized nonlinearly
via SM Higgs as a (pseudo-) dilaton. The scale symmetry forbids the new vector
boson decay to the 125 GeV Higgs plus W/Z boson, in sharp contrast to the
conventional "equivalence theorem" which is invalidated by the conformality.
The HLS forbids mixing between the iso-triplet technirho's, rho_{Pi} and
rho_{P}, of the one-family walking technicolor (with four doublets
N_D=N_F/2=4), which, without the HLS, would be generated when switching on the
standard model gauging. We also present updated analyses of the walking
technrho's for the diboson excesses by fully incorporating the constraints from
the conformal barrier and the HLS as well as possible higher order effects:
still characteristic of the one-family walking technirho is its smallness of
the decay width, roughly of order Gamma/M_rho ~ [3/N_C x 1/N_D] x
[Gamma/M_rho]_{QCD} ~ 70 GeV/2TeV (N_D= N_C=4), in perfect agreement with the
expected diboson resonance with Gamma<100 GeV. The model is so sharply
distinguishable from other massive spin 1 models without the conformality and
HLS that it is clearly testable at the LHC Run II. If the 2 TeV boson decay to
WH/ZH is not observed in the ongoing Run II, then the conformality is operative
on the 125 GeV Higgs, strongly suggesting that the 2 TeV excess events are
responsible for the walking technirhos and the 125 GeV Higgs is the
technidilaton.
