Gauge copies and the fate of background independence in Yang-Mills theories: a leading order analysis
O. C. Junqueira, I. F. Justo, D. S. Montes +2
In this work we investigate the effects of the Gribov prescription to get rid of zero-modes of the Faddeev-Popov operator, at one-loop order in perturbation theory, in the Landau-D…
Quantum corrections to finite radius holography and holographic entanglement entropy
William Donnelly, Elise LePage, Yan-Yan Li +2
We calculate quantum corrections to holographic entanglement entropy in the proposed duality between -deformed holographic 2D CFTs and gravity in AdS with a finite…
Infinitesimal Gribov copies in gauge-fixed topological Yang-Mills theories
D. Dudal, C. P. Felix, O. C. Junqueira +5
We study the Gribov problem in four-dimensional topological Yang-Mills theories following the Baulieu-Singer approach in the (anti-)self-dual Landau gauges. This is a gauge-fixed a…

O. C. Junqueira, A. D. Pereira, G. Sadovski +2
Quantum properties of topological Yang-Mills theory in (anti-)self-dual Landau gauge were recently investigated by the authors. We extend the analysis of renormalizability for two…
The universal character of Zwanziger's horizon function in Euclidean Yang-Mills theories
M. A. L. Capri, D. Dudal, M. S. Guimaraes +4
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 preci…

B. W. Mintz, L. F. Palhares, S. P. Sorella +1
We consider Yang-Mills theories quantized in the Landau gauge in the presence of the Gribov horizon via the refined Gribov Zwanziger (RGZ) framework. As the restriction of the gaug…
Renormalizability of the Refined Gribov-Zwanziger action in the linear covariant gauges
M. A. L. Capri, D. Fiorentini, A. D. Pereira +1
The Refined Gribov-Zwanziger framework takes into account the existence of equivalent gauge field configurations in the gauge-fixing quantization procedure of Euclidean Yang-Mills…
Topological Yang-Mills theories in self-dual and anti-self-dual Landau gauges revisited
O. C. Junqueira, A. D. Pereira, G. Sadovski +2
We reconsider the renormalizability of topological Yang-Mills field theories in (anti-)self-dual Landau gauges. By employing algebraic renormalization techniques we show that there…
Axial gravity, massless fermions and trace anomalies
L. Bonora, M. Cvitan, P. Dominis Prester +3
This article deals with two main topics. One is odd parity trace anomalies in Weyl fermion theories in a 4d curved background, the second is the introduction of axial gravity. The…
A non-perturbative study of matter field propagators in Euclidean Yang-Mills theory in linear covariant, Curci-Ferrari and maximal Abelian gauges
M. A. L. Capri, D. Fiorentini, A. D. Pereira +1
In this work, we study the propagators of matter fields within the framework of the Refined Gribov-Zwanziger theory, which takes into account the effects of the Gribov copies in th…
Non-perturbative aspects of Euclidean Yang-Mills theories in linear covariant gauges: Nielsen identities and a BRST invariant two-point correlation function
M. A. L. Capri, D. Dudal, A. D. Pereira +5
In order to construct a gauge invariant two-point function in a Yang-Mills theory, we propose the use of the all-order gauge invariant transverse configurations A^h. Such configura…

We prove the renormalizability to all orders of a refined Gribov-Zwanziger type action in linear covariant gauges in four-dimensional Euclidean space. In this model, the Gribov cop…

The understanding of the non-perturbative regime of YM theories remains a challenging open problem in theoretical physics. Notably, a satisfactory description of the confinement of…
A local and BRST-invariant Yang-Mills theory within the Gribov horizon

We point out the existence of a non-perturbative exact nilpotent BRST symmetry for the Gribov-Zwanziger action in the Landau gauge. We then put forward a manifestly BRST invariant…
