We propose a new mechanism to generate the electroweak scale within the
framework of QCD, which is extended to include conformally invariant scalar
degrees of freedom belonging to a larger irreducible representation of
SU(3)c. The electroweak symmetry breaking is triggered dynamically via the
Higgs portal by the condensation of the colored scalar field around 1 TeV. The
mass of the colored boson is restricted to be 350 GeV ≲mS≲ 3
TeV, with the upper bound obtained from perturbative renormalization group
evolution. This implies that the colored boson can be produced at LHC. If the
colored boson is electrically charged, the branching fraction of the Higgs
decaying into two photons can slightly increase, and moreover, it can be
produced at future linear colliders. Our idea of non-perturbative EW scale
generation can serve as a new starting point for more realistic model building
in solving the hierarchy problem.Comment: 5 pages, 3 figures. Title changed, references added, matches version
