Yang–Mills theories are an important building block of the standard model and in particular
of quantum chromodynamics. Its correlation functions describe the behavior of its …

Exact nilpotent nonperturbative BRST symmetry for the Gribov-Zwanziger action in the linear
covariant gauge Page 1 Exact nilpotent nonperturbative BRST symmetry for the …

Abstract Pure Yang–Mills SU (N) theory is studied in the Landau gauge and four
dimensional space. While leaving the original Lagrangian unmodified, a double perturbative …

Analytical functions for the propagators of QCD, including a set of chiral quarks, are derived
by a one-loop massive expansion in the Landau gauge, deep in the infrared. By analytic …

In this paper, we discuss the gluon propagator in the linear covariant gauges in D= 2, 3, 4
Euclidean dimensions. Nonperturbative effects are taken into account via the so-called …

The infrared behavior of the quark propagator is studied at one loop and in the Landau
gauge (ξ= 0) using the screened massive expansion of full QCD and three different …

We introduce a background gauge akin to the Landau-DeWitt gauge but deformed by the
presence of a gauge parameter for the quantization of Euclidean Yang-Mills theories. In the …

The refined Gribov-Zwanziger framework takes into account the existence of equivalent
gauge field configurations in the gauge-fixing quantization procedure of Euclidean Yang …

In light of the recently established BRST invariant formulation of the Gribov–Zwanziger
theory, we show that Zwanziger's horizon function displays a universal character. More …

We address the issue of the renormalizability of the gauge-invariant nonlocal dimension-two
operator A min 2, whose minimization is defined along the gauge orbit. Despite its nonlocal …
