Abstract:

The gluon propagator has been calculated for quenched QCD in the Landau gauge at $\beta$ = 6.0 for volumes 16³ x 48 and 32³ x 64, and at $\beta$ = 6.2 for volume 24³ x 48. The large volume and different lattice spacings allow us to identify and minimise finite volume and finite lattice spacing artefacts. We also study the tensor structure of the gluon propagator, confirming that it obeys the lattice Landau gauge condition.
