Abstract

We consider the neutrino mixing angles in an SO(10) GUT with the usual Higgs structure in which neutrino masses are explained by the type-I see-saw mechanism. The Dirac-neutrino Yukawa matrix then has a structure similar to that of the u-quark. We determine the light neutrino mass matrix through type-I see-saw mechanism using the experimentally consistent u-quark Yukawa matrix. We find that large neutrino mixing-angles emerge naturally in this model.
