Query: Quark Mass Matrices, textures and CKM precision measurements   In the light of several recent analyses pointing towards texture 4-zero
Fritzsch-like quark mass matrices as the only viable structures for quark mass
matrices, this work adopts a model independent approach to reconstruct an
alternate and simplified structure of texture specific quark mass matrices in a
generalized 'u-diagonal' basis within the Standard Model framework using the
Unitarity of CKM matrix and the observed hierarchies in quark mass spectra and
mixing angles. It is observed that the measured 1$\sigma$ values of the three
physical parameters namely $m_{\rm{u}}$, $m_{\rm{d}}$ and $s_{12}$ naturally
lead to the vanishing of (11) element in the down type quark mass matrix and
that the single measurable CP violating phase $\delta_{13}$ in the CKM matrix
is sufficient enough in $M^{\prime}_{\rm{d}}$ to explain the observed mixing
pattern in a suitable basis. The leading order as well as exact analytic
phenomenological solutions are addressed for the modest pattern of quark mass
matrices derived from CKM matrix and precision measurements of mixing
parameters.
