Gluon propagator without lattice Gribov copies

We study the gluon propagator in quenched lattice QCD using the Laplacian gauge which is free of lattice Gribov copies. We compare our results with those obtained in the Landau gauge on the lattice, as well as with various approximate solutions of the Dyson-Schwinger equations. We find a finite valu...

description We study the gluon propagator in quenched lattice QCD using the Laplacian gauge which is free of lattice Gribov copies. We compare our results with those obtained in the Landau gauge on the lattice, as well as with various approximate solutions of the Dyson-Schwinger equations. We find a finite value ~(445 MeV)–2 for the renormalized zero-momentum propagator (taking our renormalization point at 1.943 GeV) and a pole mass ~640±140 MeV.
