Leptogenesis: a Link between the Matter-Antimatter Asymmetry and Neutrino Physics
J. Orloff
Abstract
We review the experimental evidence for a net baryon density in cosmology, and the theoretical mechanism for producing it, called leptogenesis, which relies on the creation of a lepton asymmetry at an intermediate step. The naturality of this mechanism and its possible relations with neutrino oscillations are outlined.
