Relation between quark masses and weak mixings
Abstract
Simple transformation formulas between fermion matrices and observables, and numerical values of quark matrices, are obtained on a particular weak basis with one quark matrix diagonal and the other with vanishing elements 1-1, 1-3 and 3-1, and with only the element 2-2 complex. When we choose Mu diagonal, then Md shows intriguing numerical properties which suggest a four parameter description of it, which implies Vus md/ms, Vcb (3/5)(ms/mb) and Vub (1/5)(md ms/mb). Few comments on mass-mixing relations are added.
