We consider the minimal U(1)$$_{B-L}$$B-L extension of the standard model (SM) with the classically conformal invariance, where an anomaly-free U(1)$$_{B-L}$$B-L gauge symmetry is introduced along with three generations of right-handed neutrinos and a U(1)$$_{B-L}$$B-L Higgs field. Because of the classically conformal symmetry, all dimensional parameters are forbidden. The $$B-L$$B-L gauge symmetry is radiatively broken through the Coleman–Weinberg mechanism, generating the mass for the $$U(1)_… CONTINUE READING
