摘要：

We investigate for two-Higgs-doublet models with intrinsic CP violation in the scalar potential CP-nonconserving effects in unpolarized gamma gamma --> t (t) over bar for a range of neutral Higgs boson masses which includes resonant phi production and the subsequent decay of phi --> t (t) over bar. The importance of taking into account, even in the resonant case, the interference with the nonresonant background is shown. Further, we propose and calculate three asymmetries which efficiently trace CP-violating effects in gamma gamma --> t (t) over bar using semileptonic t (t) over bar decays.
