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 ∼600-30 +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. ©2002 The American Physical Society.
