Dynamical symmetry breaking, CP violation, and a Higgs-like particle

A pseudoscalar associated with dynamical symmetry breaking can mix with a heavier scalar when CP is violated. We study how such a mixed state that is mostly pseudoscalar can resemble the observed 125 GeV particle. The production rate from $gg$ is enhanced by the new heavy quarks and this compensates for the reduced $WW$, $ZZ$ and $\gamma\gamma$ branching ratios. The particle can appear to be a scalar from angular distributions in $ZZ$ decay while its pseudoscalar couplings should become evident in other processes.
