摘要：

We propose a new mechanism to generate a 17 keV pseudo-Dirac neutrino naturally without subscribing to the see-saw mechanism. The nu-L's combine with the only sterile neutrino of the model to form a Dirac neutrino at the one-loop level. Two-loop contributions generate small masses for nu-e and nu-mu, the mass squared difference and the mixing being of the right magnitude to solve the solar neutrino puzzle. The 17 keV neutrino decays very fast into the lighter neutrinos and a singlet-doublet majoron.
