Scientific paper

The experimental observation of a massive (17-keV) component of the electron neutrino (Simpson, 1985) is examined theoretically, applying the majoron hypothesis of Gelmini and Roncadelli (1981), Gelmini et al. (1982), and Georgi et al. (1983). In this model, spontaneous breaking of B-L symmetry occurs in the very early universe, and two massive neutrinos (nuH) interact to form two massless Goldstone bosons (phi), resulting in the annihilation of almost all nuH as soon as they became nonrelativistic, as long as the nuH/phi coupling constant is greater than 0.00001. The generation of cosmologically safe massive neutrinos in this scenario is demonstrated, and the model's attractiveness as an element of a standard cosmological model and its experimental testability are considered.
