Scientific paper

The cosmological constraints on neutrino masses can be altered if lepton number is broken globally giving rise to a very weakly coupled Goldstone boson - the majoron. Then heavy neutrinos can decay sufficiently rapidly by majoron emission, thereby giving negligible contributions to the mass density of the universe. Specifically, if M is the mass scale associated with lepton number breakdown, for M less than approximately 10 to the 6th GeV there are no constraints on neutrino masses while for M high enough (M greater than approximately 10 to the 9th to 10 to the 10th GeV) the standard bounds remain.
