2026-07-072026-07-07http://salesiana.dossiersoluciones.com/handle/123456789/44653We investigate a possible CP violating effect in $e^+e^-$ annihilation into $t\bar t$ top quark pairs. As an illustrative example, we assume the source of the CP nonconservation is in the Yukawa couplings of a neutral Higgs boson which contain both scalar and pseudoscalar pieces. One of the interesting observable effects is the difference in production rates between the two CP conjugate polarized $t\bar t$ states.9 pages, 3 postscript figures not included but availabel upon request, CERN-TH.6658/92High Energy Physics - Phenomenologytext
