Dark Matter and Baryogenesis from Non-Abelian Gauged Lepton Number
arXiv:1705.07297 · doi:10.1142/S021773231730018X
Abstract
A simple model is constructed based on the gauge symmetry , with only the leptons transforming nontrivially under . The extended symmetry is broken down to the Standard Model gauge group at TeV-scale energies. We show that this model provides a mechanism for baryogenesis via leptogenesis in which the lepton number asymmetry is generated by instantons. The theory also contains a dark matter candidate - the partner of the right-handed neutrino.
