b-tau unification and large atmospheric mixing: a case for non-canonical see-saw
arXiv:hep-ph/0210207 · doi:10.1103/PhysRevLett.90.051802
Abstract
We study the second and third generation masses in the context of the minimal renormalizable SO(10) theory. We show that if the see-saw takes the non-canonical (type II) form, large atmospheric neutrino mixing angle requires b-tau unification.
