Abstract
The cosmological baryon asymmetry can be explained by the nonperturbat ive electroweak reprocessing of a lepton asymmetry generated in the ou t-of-equilibrium decay of heavy right-handed Majorana neutrinos. We an alyze this mechanism in detail in the framework of a SO(10)-subgroup. We take three right-handed neutrinos into account and discuss physical neutrino mass matrices.
