Abstract
We study $CP$ violation in ${e}^{+}{e}^{\ensuremath{-}}\ensuremath{\rightarrow}{\stackrel{\texttildelow{}}{\ensuremath{\chi}}}_{i}^{+}{\stackrel{\texttildelow{}}{\ensuremath{\chi}}}_{j}^{\ensuremath{-}}$ in the framework of the minimal supersymmetric standard model. Though the cross section of this process is $CP$-even at the tree level even for polarized electron-positron beams, we show that it contains a $CP$-odd part at one-loop order and there are $CP$-odd observables that can in principle be measured even using unpolarized electron-positron beams. The relevant diagram calculations are briefly discussed, and the results of selected (box) diagram computations are shown.
