CP-ODD NEUTRAL HIGGS EFFECTS IN $t\bar t$ PRODUCTION

Abstract

We study CP violation in the process [Formula: see text] at an e+e− TeV collider. As the source of CP violation we assume a two-Higgs doublet model with an explicitly CP- noninvariant Higgs potential. The finite width effects of the neutral Higgs boson in the subprocess reaction, [Formula: see text], give rise to CP-odd observables which can have sizeable values. CPT constraints due to final (initial) state interactions are also taken into account. Numerical estimates of the expected CP asymmetry are given.
