Leptogenesis in a model with Friedberg-Lee symmetry
arXiv:0906.1903 · doi:10.1016/j.physletb.2009.09.015
Abstract
We study the matter-antimatter asymmetry through the leptogenesis mechanism in a specific model with the Friedberg-Lee (FL) symmetry.We relate the leptogenesis with the CP violating Dirac and Majorana phases in the Maki-Nakagawa-Sakata leptonic mixing matrix and illustrate the net baryon asymmetry of the universe in terms of these phases.
