Scientific paper

We propose T-odd and CP-odd odd asymmetries in order to analyze the impact of CP violating phases in neutralino production and subsequent leptonic two-body decays. We present numerical results of these asymmetries and of the cross sections for complex parameters \mu, M_1 and A_\tau, which may be present in the neutralino and stau sector of the Minimal Supersymmetric Standard Model if CP is violated. The asymmetries arise on tree level and thus could be large enough to be observed at a linear e+e- collider in the \sqrt{s}=500 GeV range with high luminosity. We discuss the feasibility for measuring the asymmetries by analyzing their statistical errors. Moreover we study the beam polarization dependence of the asymmetries and of the cross sections and show that they both can be enhanced considerably.
