摘要：

We propose a new scenario for generating the baryon asymmetry in the universe within the framework of the inflationary cosmology. The decay of the weakly coupled inflation field via the heavy Majorana neutrinos produces an asymmetry in one or more species of the light neutrinos. The subsequent appearance of rapid fermion-number violating processes due to nonperturbative electroweak effects transforms a specified fraction of this asymmetry to the observed baryon asymmetry. Examples based on the SO(10) model are presented.
