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.

The D0 experiment has reported a direct search for a charged Higgs boson produced by [Formula: see text] annihilation and decaying to [Formula: see text] final state, in the 180≤MH+≤300 GeV mass range. The analysis has led to upper limits on the production cross-section in the framework of the two-Higgs doublet model types I, II and III. We compare the predictions of two different scenarios in the framework of the two-Higgs doublet type III to the cross-section limits reported by D0 collaboration, and we obtain constraints on the charged Higgs mass, for the case when the charged Higgs mass is bigger than the top quark mass. Also, searches for the charged Higgs boson with a mass smaller than top quark mass are considered, we discuss the possible limits on the charged Higgs boson mass obtained from measurements of the ratio [Formula: see text] within the two-Higgs doublet model type III.
