摘要：

We discuss CP violation in top-antitop production at the LHC, induced by gluon fusion and final-state Higgs exchange. Results by Bernreuther and Brandenburg are confirmed and further reduced. The lepton energy asymmetry is studied in detail in explicit two-Higgs-doublet models with near-maximal mixing in the neutral Higgs sector. Unless there is only one light Higgs particle, and unless (in "model II") tan beta less than or similar to 1, the CP-violating effects are very small, possibly too small to be seen at the LHC.
