摘要：

We extend the application of axial Ward identities to calculate b(A), b(P) and b(T), coefficients that give the mass dependence of the renormalization constants of the corresponding bilinear operators in the quenched theory. The extension relies on using operators with non-degenerate quark masses, It allows a complete determination of the O(a) improvement coefficients for bilinears in the quenched approximation using Ward Identities alone. Only the scale dependent normalization constants Z(P)(0) (or Z(S)(0)) and Z(T) are undetermined. We present results of a pilot numerical study using hadronic correlators.
