✦ Synopsis
Renormalization constants of vector (2,) and axial-vector (ZA) currents are determined non-perturbatively in quenched QCD for an RG-improved gauge action and a tadpole-improved clover quark action using the Schr6dinger functional method. Meson decay constants f, and fT show much better scaling when Zv and ZA estimated for infinite physical volume are used instead of Z-factors from tadpole-improved one-loop perturbation theory.
