摘要
I present a detailed and complete calculation of the gluino and neutralino contribution to the direct CP violating parameter epsilon' within the MSSM. I include the complete mixing matrices of the neutralinos and of the scalar partners of the left and right handed down quarks. I find that the neutralino contribution is generally small but can be larger than the gluino contribution for small values m(s) less than or equal to 400 GeV of the supersymmetric breaking scale.
