Short comment about the lattice gluon propagator at vanishing momentum
arXiv:hep-lat/0602006
Abstract
We argue that all evidences point towards a finite non-vanishing zero momentum renormalised lattice gluon propagator in the infinite volume limit. We argue that different simulations with different lattice setups end-up with fairly compatible results for the gluon propagator at zero momentum, with different positive slopes as a function of the inverse volume.
