Abstract
The gluon propagator is calculated in quenched QCD for two different lattice
sizes (163 × 48 and 323 × 64) at β = 6.0. The volume dependence of the
propagator in Landau gauge is studied. The smaller lattice is instrumental
in revealing finite volume and anisotropic lattice artefacts. Methods for minimising these artefacts are developed and applied to the larger lattice data.
New structure seen in the infrared region survives these conservative cuts to
the lattice data. This structure serves to rule out a number of models that
have appeared in the literature. A fit to a simple analytical form capturing
the momentum dependence of the nonperturbative gluon propagator is also
reported.
