                                    Resum

   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.
