Supersymmetric models provide many new complex phases which lead to CP
violating effects in collider experiments. As an example, CP-sensitive triple
product asymmetries in neutralino production and subsequent leptonic two-body
decays are studied within the Minimal Supersymmetric Standard Model. A full ILD
detector simulation has been performed at a center of mass energy of 500GeV,
including the relevant Standard Model background processes, a realistic beam
energy spectrum, beam backgrounds and a beam polarization of 80% and -60% for
the electron and positron beams, respectively. Assuming an integrated
luminosity of 500fb-1 collected by the experiment and the performance of the
current ILD detector, a relative measurement accuracy of 10% for the
CP-sensitive asymmetry can be achieved in the chosen scenario.
