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