Abstract

We have combined perturbative unitarity and renormalization group equation arguments in order to find a dynamical way to constrain the g? 1 coupling of the minimal B–L extension of the standard model. We have analysed the role of the g?
1 coupling evolution in the perturbative stability of the two-to-two body scattering amplitudes of the vector boson and scalar sectors of the model, and we have shown that perturbative unitarity imposes an upper bound on the B–L gauge coupling. We have made a comparison between this criterion and the triviality arguments, showing that our procedure substantially refines the triviality bounds.
