Gribov copies, lattice QCD and the gluon propagator
We address the problem of Gribov copies in lattice QCD. The gluon propagator is computed, in the Landau gauge, using 302 ([beta]=5.8) 124 SU(3) configurations gauge fixed to different copies. The results of the simulation shows that: (i) the effect of Gribov copies is small (less than 10%); (ii)Â Gr...
