Abstract.

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 \({\rm arg}(A_t)\). The light top squark mass is assumed to be close to the top quark mass, \(m_{\tilde{t}}\sim m_t\). The CP conserving phase is provided by the \(\chi^+\) and \(\chi^0\) 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%.
