Unconventional model of neutrino masses

Research output: Contribution to journalArticlepeer-review


Gelmini and Roncadelli have proposed a model of neutrino masses in which B-L symmetry is spontaneously broken by a small vacuum expectation value of a Higgs triplet. We give an exegesis of this model. We show that the massive neutrinos in this model cannot be cosmologically relevant today and that conflicting analyses of double beta decay experiments can be reconciled.
