Electroweak dipole moment form factors of the top quark in supersymmetry

Abstract

The CP violating electric and weak dipole moment form factors of the top quark appear in the process $e^{+}e^{-} --> t\bar{t}$. We present a complete analysis of these dipole moment form factors within the Minimal Supersymmetric Standard Model with complex parameters. We include gluino, chargino, and neutralino exchange in the loop of the $\gamma t\bar{t}$ and $Z t\bar{t}$ vertex. We give the analytic expressions and present numerical results.
