U(1) effective confinement theory from SU(2) restricted gauge theory via the Julia-Toulouse Approach
L. S. Grigorio, M. S. Guimaraes, W. Oliveira +2
We derive an U(1) effective theory of color confinement by applying the so-called Julia-Toulouse Approach for defects condensation to the SU(2) restricted gauge theory defined by m…
A remark on the BRST symmetry in the Gribov-Zwanziger theory
M. A. L. Capri, A. J. Gomez, M. S. Guimaraes +3
We show that the soft breaking of the BRST symmetry arising in the Gribov-Zwanziger theory can be converted into a linear breaking upon introduction of a set of BRST quartets of au…
On the duality in four-dimensional Lorentz-breaking field theories
M. S. Guimaraes, J. R. Nascimento, A. Yu. Petrov +1
We consider new issues of duality in four-dimensional Lorentz-breaking field theories. In particular, we demonstrate that the arising of the aether-like Lorentz-breaking term is ne…
Glueball masses from an infrared moment problem and nonperturbative Landau gauge
D. Dudal, M. S. Guimaraes, S. P. Sorella
We set up an infrared-based moment problem to obtain estimates of the masses of the scalar, pseudoscalar and tensor glueballs in Euclidean Yang-Mills theories using the Refined Gri…
From unphysical gluon and ghost propagators to physical glueball propagators (in the Gribov-Zwanziger picture): a not so trivial task?
D. Dudal, N. Vandersickel, L. Baulieu +5
During recent years, a good agreement was found between the analytical derivation and the numerical simulation of the Landau gauge gluon and ghost propagators. We mention the Schwi…
Constructing local composite operators for glueball states from a confining Gribov propagator
M. A. L. Capri, A. J. Gomez, M. S. Guimaraes +3
The construction of BRST invariant local operators with the quantum numbers of the lightest glueball states, , is worked out by making use of an Euc…
