摘要：

We study the symmetric texture of geometric form with 2-zeros to see if it is consistent with the presently-known neutrino masses and mixings. In the neutrino mass matrix elements we obtain numerically the allowed region of the parameters including CP-violating phases, which can reproduce the present neutrino experiment data. The result of this analysis dictates the narrow region for the GUT model including Pati-Salarn symmetry with texture zeros to be consistent with the experimental data. The \U-e3\ and J(CP) are also predicted in such models. (C) 2003 Elsevier B.V. All rights reserved.
