摘要：

We present a supersymmetric model of fermion masses, based on a non-Abelian family symmetry and the Froggatt-Nielsen mechanism, that can account for the solar and atmospheric neutrino problems via quasi-degenerate neutrinos. The model predicts that the ratio of neutrino mass squared splittings Delta m(12)(2) /Delta m(23)(2) is of order m(s)(2)/m(b)(2) and the angles theta(12) similar to m(d)/m(s) and theta(23) similar to 1, which are of the desired orders of magnitude. We discuss the implications of the flavor structure of the neutrino sector on superparticle masses and mixing angles. (C) 1998 Elsevier Science B.V.
