Systematic Effects at Criticality for the SU(2)-Landau-Gauge Gluon Propagator

Abstract

We analyze data from finite-temperature simulations of the gluon propagator in SU(2) Landau gauge on large lattices. We argue that the singular behavior of this quantity around the deconfinement transition, seen in several previous studies, is a lattice artifact.
