B-tau unification and large atmospheric mixing: a case for a noncanonical seesaw mechanism.
We study the second and third generation masses in the context of the minimal renormalizable SO(10) theory. We show that if the seesaw takes the noncanonical (type II) form, large atmospheric neutrino mixing angle requires b-tau unification.
