Present neutrino data are consistent with neutrino masses arising from a common seed at some “neutrino unification” scale MX. Such a simple theoretical ansatz naturally leads to quasidegenerate neutrinos that could lie in the electron-volt range with neutrino mass splittings induced by renormalization effects associated with supersymmetric thresholds. In such a scheme the leptonic analog of the Cabibbo angle θ⊙ describing solar neutrino oscillations is nearly maximal. Its exact value is correlated with the smallness of θreactor. The two leading mass-eigenstate neutrinos present in νe form a pseudo-Dirac neutrino, avoiding conflict with neutrinoless double beta decay.
