Abstract

Interactions of heavy Majorana neutrinos in the thermal phase of the early universe may be the origin of the cosmological baryon asymmetry. We review this leptogenesis mechanism with emphasis on the quantitative connection with neutrino masses. We also comment on the implications for dark matter and the possibility that gravitinos are its main component.
