An SO(10) GUT Model With Lopsided Mass Matrix and Neutrino Mixing Angle theta_13

Abstract

An alternative supersymmetric SO(10) grand unification model with lopsided fermion mass matrices is introduced. It generates a large solar-neutrino-mixing angle through the neutrinos' Dirac mass matrix constrained by the SO(10) group structure, avoiding the fine-tuning required in the Majorana mass matrix of right-handed neutrinos. The model fits well the known data on masses and mixings of quarks and leptons, and predicts a sizable lepton mixing ${\sin }^{2}2{\theta }_{13}\simeq 0.074$, which is significantly larger than that of the original lopsided model.
