  After a short review of baryogenesis mechanisms, we focus on the charge
transport mechanism at the electroweak scale, effective at strong electroweak
phase transitions. Starting from the one-loop Schwinger-Dyson equations for
fermions coupled to bosons, we present a derivation of the relevant kinetic
equations in the on-shell and gradient approximations, relevant for the thick
wall baryogenesis regime. We then discuss the CP-violating source from the
semiclassical force in the flow term, and compare it with the source arising in
the collision term of the kinetic equation. Finally, we summarize the results
concerning the chargino mediated baryogenesis in the Minimal Supersymmetric
Standard Model.
