Comparing SU(2) to SU(3) gluodynamics on large lattices
Abstract
We study the SU(2) gluon and ghost propagators in Landau gauge on lattices up to a size of 1124. A comparison with the SU(3) case is made and finite-volume effects are then investigated. We find that for a large range of momenta the SU(2) and SU(3) propagators are remarkably alike. In the low-momentum region we compare with recent results obtained in DSE studies on a 4-torus.
