CP violation in semi-leptonic decays of the top quark within MSSM
Description
We calculate the CP violating effects in the top quark semi-leptonic three body decays induced by the supersymmetric CP-odd phase of the top squark trilinear soft breaking term arg(At). The light top squark mass is assumed to be close to the top quark mass, mt∝mt. The CP conserving phase is provided by the χ+ and χ0 cut. We find that the partial rate asymmetry is on the 0.1% level. In the most favorable parameter region the decay rate asymmetry can reach up to 0.55%. (orig.)
