# Aspects of the Gribov-Zwanziger framework

@article{Dudal2009AspectsOT, title={Aspects of the Gribov-Zwanziger framework}, author={David Dudal and Nele Vandersickel and Henri Verschelde and Silvio Paolo Sorella}, journal={arXiv: High Energy Physics - Theory}, year={2009} }

The existence of gauge (Gribov) copies disturbs the usual Faddeev-Popov quantization procedure in the Landau gauge. It is a very hard job to treat these in the continuum, even in a partial manner. A decent way to do so was worked out by Gribov, and later on by Zwanziger. The final point was a renormalizable action (the Gribov-Zwanziger action), implementing the restriction of the path integration to the so-called Gribov region, which is free of a subset of gauge copies, but not of all copies…
