CP violation in top pair production at an e^+e^- collider

Abstract

We investigate a possible CP violating effect in $e^{+}{e}^{-}$ annihilation into $t\bar{t}$ top quark pairs. As an illustrative example, we assume the source of the CP nonconservation is in the Yukawa couplings of a neutral Higgs boson which contain both scalar and pseudoscalar pieces. One of the interesting observable effects is the difference in production rates between the two CP conjugate polarized $t\bar{t}$ states.
