Title: Spontaneous lepton-number breaking at electroweak scale

Abstract

We propose some new models with spontaneous lepton-number breaking where the nuetrino masses and the couplings of the Goldstone boson (majoron) to charged fermions are naturally small because they arise in quantum loops. Thus, unlike other majoron models, we do not have to invoke any new scale in the model which is very different from the electroweak scale.
