    Abstract:

    A simple model is constructed based on the gauge symmetry SU(3)c×SU(2)L×U(1)Y × SU(2)l, with only the leptons transforming nontrivially under SU(2)l. 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 SU(2)l instantons. The theory also contains a dark matter candidate — the SU(2)l partner of the right-handed neutrino.
