We investigate a possible CP violating effect in e+e− annihilation into
ttˉ 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 ttˉ states.Comment: 9 pages, 3 postscript figures not included but availabel upon
