CP violation in top quark production at the LHC and Two-Higgs-Doublet Models

Nucl.Phys. B661 (2003) 209-234 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-Double...

Summary:Nucl.Phys. B661 (2003) 209-234 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) tanbeta \lsim 1, the CP-violating effects are very small, possibly too small to be seen at the LHC.
