Non-perturbative renormalization constants using Ward identities

Journal Article (Journal Article)

We extend the application of vector and axial Ward identities to calculate b , b and b , 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 (or Z ) and Z are undetermined. We present results of a pilot numerical study using hadronic correlators. A P T P S T 0 0
