Abstract
Renormalization constants of vector (Zv) 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 Schrödinger functional method. Meson decay constants p and fπ show much better scaling when Zv and ZpA estimated for infinite physical volume are used instead of Z-factors from tadpole-improved one-loop perturbation theory.
