Abstract
A nearly historical account of quark mass matrix models is given, and the structure of quark mass matrices in the standard model is studied. For a minimal parameter basis suggested earlier, where Mu is diagonal and Md11, Md13, Md31 are zero, the dependence of mass matrices on the CP violating phase δ of V CKM is reported: all parameters are almost independent, except Md22 and Md23, and the equality |Md22| = Md23 is obtained for a value of δ very close to the value which is favored by experiments. Moreover, on this basis, Md12≃Md21 and Md33≃2Md32. Some comments on mass matrices in left–right symmetric models are added.Keywords
