Finite Temperature Landau Gauge Lattice Quark Propagator
Orlando Oliveira, Paulo J. Silva
The quark propagator at finite temperature is investigated using quenched gauge configurations. The propagator form factors are investigated for temperatures above and below the gl…
Spectral representation of lattice gluon and ghost propagators at zero temperature
David Dudal, Orlando Oliveira, Martin Roelfs +1
We consider the analytic continuation of Euclidean propagator data obtained from 4D simulations to Minkowski space. In order to perform this continuation, the common approach is to…
Faddeev-Popov Matrix in Linear Covariant Gauge: First Results
Attilio Cucchieri, David Dudal, Tereza Mendes +3
We discuss a possible definition of the Faddeev-Popov matrix for the minimal linear covariant gauge on the lattice and present first results for the ghost propagator. We consider Y…
Quark propagator with two flavors of O(a)-improved Wilson fermions
Orlando Oliveira, Paulo J. Silva, Jon-Ivar Skullerud +1
We compute the Landau gauge quark propagator from lattice QCD with two flavors of dynamical O(a)-improved Wilson fermions. The calculation is carried out with lattice spacings rang…
High Precision Statistical Landau Gauge Lattice Gluon Propagator Computation vs. the Gribov-Zwanziger approach
David Dudal, Orlando Oliveira, Paulo J. Silva
The compatibility of the results from the Gribov-Zwanziger tree level prediction and lattice simulations, using large statistical ensembles, for the Landau gauge gluon propagator a…
Finite temperature gluon propagator in Landau gauge: non-zero Matsubara frequencies and spectral densities
Paulo J. Silva, Orlando Oliveira, David Dudal +1
We report on the lattice computation of the Landau gauge gluon propagator at finite temperature, including the non-zero Matsubara frequencies. Moreover, the corresponding Källén-Le…
Reply to "Comment on 'Lattice Gluon and Ghost Propagators, and the Strong Coupling in Pure SU(3) Yang-Mills Theory: Finite Lattice Spacing and Volume Effects' "
Anthony G. Duarte, Orlando Oliveira, Paulo J. Silva
The quenched gluon and ghost propagator data published in [1] is reanalysed following the suggestion of [2] to resolve the differences between the infrared data of the simulations.…
Approximate dual representation for Yang-Mills SU(2) gauge theory
R. Leme, O. Oliveira, G. Krein
An approximate dual representation for non-Abelian lattice gauge theories in terms of a new set of dynamical variables, the plaquette occupation numbers (PONs) that are natural num…
Gluons at finite temperature
P. J. Silva, O. Oliveira, D. Dudal +2
The gluon propagator is investigated at finite temperature via lattice simulations. In particular, we discuss its interpretation as a massive-type bosonic propagator. Moreover, we…
Gluon and Ghost Dynamics from Lattice QCD
O. Oliveira, A. G. Duarte, D. Dudal +1
The two point gluon and ghost correlation functions and the three gluon vertex are investigated, in the Landau gauge, using lattice simulations. For the two point functions, we dis…
Lattice Gluon and Ghost Propagators, and the Strong Coupling in Pure SU(3) Yang-Mills Theory: Finite Lattice Spacing and Volume Effects
Anthony G. Duarte, Orlando Oliveira, Paulo J. Silva
The dependence of the Landau gauge two point gluon and ghost correlation functions on the lattice spacing and on the physical volume are investigated for pure SU(3) Yang-Mills theo…
Gluon Dynamics, Center Symmetry and the deconfinement phase transition in SU(3) pure Yang-Mills theory
P. J. Silva, O. Oliveira
The correlations between the modulus of the Polyakov loop, its phase and the Landau gauge gluon propagator at finite temperature are investigated in connection with the center…
The lattice gluon propagator in renormalizable gauges
P. Bicudo, D. Binosi, N. Cardoso +2
We study the SU(3) gluon propagator in renormalizable gauges implemented on a symmetric lattice with a total volume of (3.25 fm) for values of the guage fixing parameter…
