Threshold Effects on Quasi-degenerate 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 quasi-degenerate 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 $\mathrm{KamLAND}$ and $\mathrm{SNO}$ on observations of neutrino oscillations.
