Minimal texture of quark mass matrices and precision CKM measurements

TL;DR

This paper systematically analyzes minimal texture quark mass matrices and finds all such configurations incompatible with current quark mixing data, with conclusions remaining robust despite potential future changes in quark mass ranges.

Contribution

It provides a comprehensive analysis of 169 minimal texture quark mass matrices and demonstrates their incompatibility with experimental data.

Findings

All 169 texture 6 zero combinations are ruled out.

Many are analytically excluded, others by current data.

Conclusions remain valid despite future quark mass range changes.

Abstract

We have carried out an extensive analysis of all possible minimal texture quark mass matrices implying 169 texture 6 zero combinations. One finds that all these combinations are ruled out, a good number of these analytically, the other possibilities are excluded by the present quark mixing data. Interestingly, even if in future, there are changes in the ranges of the light quark masses, these conclusions remain valid.
