Critical Point in a 3-3-1 Model with Right-Handed Neutrinos - High Energy Physics - Phenomenology

Abstract: The boson mass spectrum of a 3-3-1 model with right-handed neutrinos isinvestigated by tuning a unique free parameter whitin the exact algebraicalapproach for solving gauge models with high symmetries. A very strangecoincidence of the masses in both the neutral and the charged boson sectors canoccur at a not very high breaking scale. This could explain why the masses ofthe new bosons have not been exactly weighted in the laboratories by date. Inorder to have good phenomenological behaviour in the neutrino sector, one canresort to either the conservation of the global lepton number$L {e}-L {\mu}-L {\tau}$ or see-saw mechanism.
