Descripción
We will compute the CP-violating currents of the right-handed stops and Higgsinos, induced by the presence of non-trivial vacuum expectation values of the Higgs fields within the context of the minimal supersymmetric extension of the Standard Model (MSSM) with CP-violating phases. We will perform the computation at finite temperature, using the Keldysh formalism, in an expansion of derivatives of the Higgs fields. We perform a resummation of the Higgs mass insertion effects to all orders in perturbation theory. The total contribution leads to acceptable values of the baryon asymmetry for values of the CP-violating phases in the range 0.02 < | sin \phi CP | < 1.
