Phenomenology of the minimal B-L extension of the SM

In this talk I will review the results we obtained for the so-called B-L model, a minimal U(1) extension of the SM related to the Baryon minus Lepton charge. Three RH-neutrinos are required for the anomaly cancellation, thereby naturally providing neutrino masses through a dynamical implementation of the see-saw mechanism. This minimal extension also includes one new vector state (Z') and an additional Higgs boson. I will hence present the results of our investigation of the phenomenology of the new states, discussing in detail each sector and its consequences for collider searches. New interesting signatures arise: for instance, multilepton decays of the Z' boson and of the Higgs boson(s) as well as distinctive displaced vertices. The allowed parameter space and the present experimental constraints will also be discussed.
