CP Violation in Supersymmetry
Abstract
A review about some recent studies on the determination of the CP-violating complex parameters in supersymmetry at an e^+ e^- linear collider is presented. CP-even observables, like masses, cross sections and branching ratios, can have a strong dependence on the supersymmetric phases. However, CP-odd observables, like asymmetries based on triple product correlations, are necessary to unambiguously establish CP violation. In the chargino and neutralino sector these asymmetries can be as large as 30 % and will therefore be an important tool for the search for CP-violating effects in supersymmetry.
