Absence of radiative corrections in 4-dimensional topological Yang-Mills theories
O. C. Junqueira, A. D. Pereira, G. Sadovski +2
We prove that all connected n-point Green functions of four-dimensional topological Yang-Mills theories quantized in the (anti-)self-dual Landau gauges are tree-level exact, i.e. t…

A first survey of the ghost-gluon vertex in the Gribov-Zwanziger framework
B. W. Mintz, L. F. Palhares, S. P. Sorella +1
As the restriction of the gauge fields to the Gribov region is taken into account, it turns out that the resulting gauge field propagators display a nontrivial infrared behavior, b…

Non-perturbative BRST quantization of Euclidean Yang-Mills theories in Curci-Ferrari gauges
A. D. Pereira, R. F. Sobreiro, S. P. Sorella
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-Zw…
