  We make use of the formalism developed in Ref. [1], and calculate the
chargino mediated baryogenesis in the Minimal Supersymmetric Standard Model.
The formalism makes use of a gradient expansion of the Kadanoff-Baym equations
for mixing fermions. For illustrative purposes, we first discuss the
semiclassical transport equations for mixing bosons in a space-time dependent
Higgs background. To calculate the baryon asymmetry, we solve a standard set of
diffusion equations, according to which the chargino asymmetry is transported
to the top sector, where it biases sphaleron transitions. At the end we make a
qualitative and quantitative comparison of our results with the existing work.
We find that the production of the baryon asymmetry of the Universe by
CP-violating currents in the chargino sector is strongly constrained by
measurements of electric dipole moments.
