Non-perturbative BRST quantization of Euclidean Yang-Mills theories in Curci-Ferrari gauges
Abstract
In this paper we address the issue of the non-perturbative quantization of Euclidean Yang-Mills theories in the Curci-Ferrari gauge. In particular, we construct a Refined Gribov-Zwanziger action for this gauge which takes into account the presence of gauge copies as well as the dynamical formation of dimension two condensates. This action enjoys a non-perturbative BRST symmetry recently proposed in Capri:2015ixa. Finally, we give attention to the gluon propagator in different space-time dimensions.
