In this work, we investigate a minimal SU SU U U (3) (3) (1) (1) C LXN(3-3-1-1) model and argue how it improves the phenomenological and theoretical aspects of the known minimal 3-3-1 model. The lepton content includes only the standard model leptons, which form (3)L SU (anti)triplets, and the right-handed neutrinos, which transform as (3)L SU singlets, in order to cancel the B L − anomalies. We show that the electroweak and B L − interactions are unified, similarly to the electroweak theory, at the TeV scale. There is a residual symmetry of the gauge symmetry, called W -parity, which makes extra wrong B L − particles stabilized, provides dark matter candidates. |
