Dynamical symmetry breaking, CP violation, and a Higgs-like particle
arXiv:1301.0329 · doi:10.1016/j.physletb.2013.03.039
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 is enhanced by the new heavy quarks and this compensates for the reduced , and branching ratios. The particle can appear to be a scalar from angular distributions in decay while its pseudoscalar couplings should become evident in other processes.
