摘要：

We present the symmetry realization of the phenomenologically viable Frampton-Glashow-Marfatia (FGM) two zero texture neutrino mass matrices in the flavor basis within the framework of the type (I + II) seesaw mechanism natural to SO(10) grand unification. A small Abelian cyclic symmetry group Z(3) is used to realize these textures except for class C for which the symmetry is enlarged to Z(4). The scalar sector is restricted to the Standard Model (SM) Higgs doublet to suppress the flavor changing neutral currents. Other scalar fields used for symmetry realization are at the most two scalar triplets and, in some cases, a complex scalar singlet. Symmetry realization of one zero textures has, also, been presented. (C) 2011 Published by Elsevier B.V.
