Investigating non-Fritzsch like texture specific quark mass matrices

TL;DR

This paper systematically examines various quark mass matrix textures, finding that all texture 6 zero configurations are incompatible with data, while only Fritzsch-like texture 5 zero matrices remain viable.

Contribution

It provides a comprehensive analysis of texture-specific quark mass matrices, ruling out all but Fritzsch-like texture 5 zero matrices based on current data.

Findings

All texture 6 zero matrices are incompatible with quark mixing data.

Only Fritzsch-like texture 5 zero matrices remain viable.

Non-Fritzsch-like textures are ruled out by experimental constraints.

Abstract

A detailed investigation of all possible textures of Fritzsch-like and non-Fritzsch like, 144 for texture 6 zero and 432 for texture 5 zero mass matrices, have been carried out to ascertain their compatibility with the existing quark mixing data. It seems that all the texture 6 zero possibilities are completely ruled out whereas in the case of texture 5 zero mass matrices the only viable possibility looks to be that of Fritzsch-like.
