摘要：

We extend our study of the gluon propagator in quenched lattice QCD using the Laplacian gauge to a finer lattice. We verify the existence of a pole mass as we take the continuum limit and deduce a value of similar to600(-30)(+150) MeV for this pole mass. We find a finite value of [454(5) MeV](-2) for the renormalized zero-momentum propagator, in agreement with results on coarser lattices.
