摘要：

We show that the assumption of type II seesaw mechanism for small neutrino masses coupled with b-tau mass unification in a minimal SUSY SO(10) model leads not only to a natural understanding of large atmospheric mixing angle (theta(23)) among neutrinos, as recently noted, but also to large solar angle (theta(12)) and a small theta(13) drop U-e3 as required to fit observations. No additional symmetries are required to obtain large neutrino mixings. The proposed long baseline neutrino experiments will provide a crucial test of this model since it predicts U-e3 similar or equal to 0.16. (C) 2003 Published by Elsevier B.V.
