Gauge fixing methods and Gribov copies effects in lattice QCD
arXiv:0710.0669
Abstract
We compare two Landau gauge fixing methods, aiming to find the global maximum of the gauge fixing functional. Moreover, a systematic effect of Gribov copies in the gluon and ghost propagators computed in Landau gauge is presented and discussed.
