Abstract
We report on advances in the non-perturbative determination of the ratio ZS/ZP of the pseudoscalar to the scalar renormalization constants in three-flavour lattice QCD with Wilson-clover quarks and tree-level Symanzik improved gluons. The computations are based on the Ward identity approach, using Schrödinger functional boundary conditions. Our results for ZS/ZP cover a range of couplings along a line of constant physics with lattice spacings of about 0.09fm and below, relevant for phenomenological applications such as the calculation of renormalized quark masses.
