Generation of Large Lepton Asymmetries
J. A. Casas, Wai Yan Cheng, G. B. Gelmini
We present here a realistic model to produce a very large lepton asymmetry L of 0.1 to 1, without producing a large baryon asymmetry. The model is based on the Affleck and Dine sce…

Antonio Bouzas, Wai Yan Cheng, Graciela Gelmini
We consider a model for generating a particle-antiparticle asymmetry through out-of-equilibrium decays of a massive particle due to non-renormalizable, effective interactions.
