  When the Higgs sector of the standard model is replaced by a flavor doublet
of color sextet quarks, dynamical electroweak symmetry breaking occurs, with
the electroweak scale identified as the sextet chiral scale. Above the
electroweak scale QCD is almost scale-invariant, leading to the high-momentum
enhancement of both the sextet chiral condensate and instanton interactions.
The instanton interactions combine with the sextet condensate to produce
electroweak scale chirality violating processes in both the triplet and sextet
sectors. If the enhancement is sufficient, an electroweak scale top mass can be
produced and the $\eta_6$ axion mass can be raised, potentially providing a
consistent description of both Strong CP conservation and electroweak-scale CP
violation. The instanton interactions also produce electroweak scale chirality
violating scattering processes for light quarks and additionally modify QCD
evolution at the electroweak scale. Such effects could explain the excesses in
the DIS cross-section at HERA and jet cross-sections at the Tevatron.
