Threshold effects on quasidegenerate neutrinos with high-scale mixing unification

Abstract

We consider threshold effects on neutrino masses and mixings in a recently proposed model for understanding large solar and atmospheric mixing angles using radiative magnification for the case of quasidegenerate neutrinos. We show that the magnitude of the threshold effects is sufficient to bring concordance between the predictions of this model and latest data from KamLAND and SNO on observations of neutrino oscillations.
