| dc.description | In the presence of anomaly induced sphaleron process, only a B-L asymmetry can be partially converted to the baryon asymmetry while any B+L asymmetry would be completely erased. Thus in any successful baryogenesis theories, B-L is usually violated above the electroweak scale to explain the observed matter-antimatter asymmetry of the universe. However, if any lepton asymmetry is not affected by the sphaleron processes, a B-L conserved theory can still realize the baryogenesis. We present here an SU(5) GUT realization of this scenario, which naturally accommodates small masses of Dirac neutrinos. | |
