CKM mixings from mass matrices with five texture zeros

In this work we carry out an exhaustive study to find quark mass matrices in the Standard Model~(SM), with maximum number of texture zeros consistent experimental data. We found four viable configurations five that adjust masses, mixing angles and CP violation phase, deviations below $1\sigma$ level respect current SM best fit values. One most important aspects is economic procedure zeros: resort weak basis transformation method, which, as will show, exhaustively search every possible configuration. report various leading order relations between masses for each case.
