Abstract

The CP violating electric and weak dipole moment form factors of the top quark, \dgs\dgs and \dzs\dzs, appear in the process \mbox{e+ettˉe^{+}e^{-} \to t \bar{t}}. We present a complete analysis of these dipole moment formfactors within the Minimal Supersymmetric Standard Model with complex parameters. We include gluino, chargino, and neutralino exchange in the loop of the \mbox{γttˉ\gamma t\bar{t}} and \mbox{ZttˉZ t\bar{t}} vertex. We give analytic expressions and present numerical results for the asymmetries that measure these formfactors.
