Finiteness of the Yang-Mills-Chern-Simons action in linear covariant gauges by taking into account gauge copies
Daniel O. R. Azevedo, Antonio D. Pereira
In recent years, the effects of removing infinitesimal Gribov copies from the path integral of gauge-fixed Yang-Mills-Chern-Simons theories formulated in three-dimensional Euclidea…
On the consistency of Lorentz-Violating Yang-Mills theories: Gauge invariance and non-perturbative effects
Antonio D. Pereira
Previous investigations on the renormalizability properties of Lorentz-violating Yang-Mills (LVYM) theories in the Landau gauge have pointed out the necessity of the inclusion of a…
Infrared gluon propagator in the Refined Gribov-Zwanziger scenario at one-loop order in the Landau gauge
Gustavo P. de Brito, Antonio D. Pereira
The Refined Gribov-Zwanziger (RGZ) action in the Landau gauge provides a local and renormalizable framework to account for the existence of infinitesimal Gribov copies in the path…
Dually weighted multi-matrix models as a path to causal gravity-matter systems
Juan L. A. Abranches, Antonio D. Pereira, Reiko Toriumi
We introduce a dually-weighted multi-matrix model that for a suitable choice of weights reproduce two-dimensional Causal Dynamical Triangulations (CDT) coupled to the Ising model.…
Refined Gribov-Zwanziger theory coupled to scalar fields in the Landau gauge
Gustavo P. de Brito, Philipe De Fabritiis, Antonio D. Pereira
The Refined Gribov-Zwanziger (RGZ) action in the Landau gauge accounts for the existence of infinitesimal Gribov copies as well as the dynamical formation of condensates in the inf…
Equivalence between the Lovelock-Cartan action and a constrained gauge theory
O. C. Junqueira, A. D. Pereira, G. Sadovski +3
We show that the four-dimensional Lovelock-Cartan action can be derived from a massless gauge theory for the group with an additional BRST trivial part. The model is orig…
Non-perturbative treatment of the linear covariant gauges by taking into account the Gribov copies
M. A. L. Capri, A. D. Pereira, R. F. Sobreiro +1
In this paper, a proposal for the restriction of the Euclidean functional integral to a region free of infinitesimal Gribov copies in linear covariant gauges is discussed. An effec…
Gribov ambiguities at the Landau -- maximal Abelian interpolating gauge
A. D. Pereira, R. F. Sobreiro
In a previous work, we presented a new method to account for the Gribov ambiguities in non-Abelian gauge theories. The method consists on the introduction of an extra constraint wh…
On the elimination of infinitesimal Gribov ambiguities in non-Abelian gauge theories
A. D. Pereira, R. F. Sobreiro
An alternative method to account for the Gribov ambiguities in gauge theories is presented. It is shown that, to eliminate Gribov ambiguities, at infinitesimal level, it is require…
From Yang-Mills theory to induced gravity
T. S. Assimos, A. D. Pereira, T. R. S. Santos +3
From pure Yang-Mills action for the group in four Euclidean dimensions we obtain a gravity theory in the first order formalism. Besides the Einstein-Hilbert term…
