Neutrino Masses And Mixings

A brief review is given of some ideas for explaining neutrino masses and mixings within the context of supersymmetric grand unification. Emphasis is put on so-called lopsided models.

It is pointed out (not for the first time) that the minimal Standard Model, without additional gauge-singlet right-handed neutrinos or isotriplet Higgs fields, allows for nonvanishing neutrino masses and mixing. The required interaction term is non-renormalizable and violates B-L conservation. The ultimate explanation of this interaction term may or may not rely on grand unification.

Majorana Neutrino Mass

We derive a model-independent upper bound on the scale of Majorana-neutrino mass generation. The upper bound is [Formula: see text], where v ≃246 GeV is the weak scale and mν is the Majorana-neutrino mass. For neutrino masses implied by neutrino oscillation experiments, all but one of these bounds are less than the Planck scale, and they are all within a few orders of magnitude of the grand-unification scale.

The "complementary" Ansatz, Tr (Mν)=0, where Mν is the prediagonal neutrino mass matrix, seems a plausible approximation for capturing in a self contained way some of the content of Grand Unification. We study its consequences in the form of relations between the neutrino masses and CP violation phases.

The Masses

We investigate a particular breaking chain of the grand unification group E6. With two smallest Higgs multiplets that have Yukawa couplings to fermions, we obtain a reasonable mass spectrum for fermions. The neutrino masses are expressed in terms of the masses of the charged fermions, leading to a predictive neutrino spectrum.
