Abstract
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 γγ 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.
