Article Description

I suggest a model based on a softly broken symmetry L-L-L and on Babu's mechanism for the two-loop radiative generation of neutrino masses. The model predicts that one of the physical neutrinos (ν) is massless and that its component along the ν direction (U) is zero. Moreover, if the soft-breaking term is assumed to be very small, then the vacuum oscillations of ν have almost maximal amplitude and solve the solar-neutrino problem. New scalars are predicted in the 10 TeV energy range, and a breakdown of e--τ universality should not be far from existing experimental bounds. ©2000 The American Physical Society.
