Dynamical neutrino mass mechanisms |
|
Résumé |
The inverse Seesaw naturally explains the smallness of neutrino masses via an
approximate B-L symmetry broken only by a correspondingly small parameter. We
identify a possible dynamical generation of the inverse Seesaw neutrino mass
mechanism from the spontaneous breaking of a gauged U(1)_B-L symmetry. Anomaly
cancellation predicts the existence of extra fermions, one of them is a viable
dark matter candidate. The collider phenomenology of the Z’ gauge boson
associated to U(1)_B-L is also discussed.
In the second part of the talk we will propose a generalization of the type II
see-saw scenario which dynamically generates a very low lepton number breaking
scale from a small hierarchy. Our model presents a rich LHC phenomenology and
other interesting phenomenological aspects such as the presence of a massless
Goldstone boson and deviations of standard model Higgs couplings.
