SUSY induced CP violation in e+e- to t\bar{t}

Abstract

The CP violating electric and weak dipole moment form factors of the top quark, $\dgs$ and $\dzs$, appear in the process \mbox{$e^{+}e^{-} \to t \bar{t}$}. 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{$γt\bar{t}$} and \mbox{$Z t\bar{t}$} vertex. We give analytic expressions and present numerical results for the asymmetries that measure these formfactors.
