Abstract
Properties of neutrinos may be the origin of the matter–antimatter asymmetry of the universe. In the see–saw model for neutrino masses, this leads to important constraints on the properties of light and heavy neutrinos. In particular, an upper bound on the light neutrino masses of 0.1 eV can be derived. We review the present status of thermal leptogenesis with emphasis on the theoretical uncertainties and discuss some implications for lepton and quark mass hierarchies, CP violation and dark matter. We also comment on the ‘leptogenesis conspiracy’, the remarkable fact that neutrino masses may lie in the range where leptogenesis works best.
