Texture of fermion mass matrices in partially unified theories

Abstract

We investigate the texture of fermion mass matrices in theories with partial unification (for example $SU(2{)}_L\times SU(2{)}_R\times SU(4{)}_c$) at a scale $\sim 10^{12}$ GeV. Starting with the low energy values of the masses and the mixing angles, we find only two viable textures with atmost four texture zeros. One of these corresponds to a somewhat modified Fritzsch textures. A theoretical derivataion of these textures leads to new interesting relations among the masses and the mixing angles.
