摘要：

We propose a new mechanism for baryogenesis in supersymmetric extensions of the standard model, that does no depend on (super)GUT interactions. It occurs by the non-perturbative electroweak reprocessing of a lepton asymmetry. This lepton asymmetry is generated by the effects of lepton number violating induced operators, arising from ''see-saw'' (s)neutrino masses, which act on scalar condensate oscillations along flat directions of the supersymmetric standard model.
