Leptogenesis and Low-energy Observables
arXiv:hep-ph/0110001 · doi:10.1103/PhysRevD.65.053019
Abstract
We relate leptogenesis in a class of theories to low-energy experimental observables: quark and lepton masses and mixings. With reasonable assumptions motivated by grand unification, one can show that the CP-asymmetry parameter takes a universal form. Furthermore the dilution mass is related to the light neutrino masses. Overall, these models offer a natural explanation for a lepton asymmetry in the early universe.
