Computation of the Kugo-Ojima function from lattice simulations
Nuno Brito, Orlando Oliveira, Paulo J. Silva +3
In addition to its connection with a standard confinement criterion, the Kugo-Ojima function constitutes an indispensable component in a multitude of applications in the gauge sect…
The four-gluon vertex in Landau gauge
Manuel Colaço, Orlando Oliveira, Paulo J. Silva
The Landau gauge four-gluon vertex is studied using high statistical lattice simulations for several momentum configurations. Furthermore, the outcome of the lattice QCD simulation…
Deconfinement, Center Symmetry and the Ghost Propagator in Landau Gauge Pure SU(3) Yang-Mills Theory
V\'{\I}tor Paiva, Paulo J. Silva, Orlando Oliveira
The temperature dependence of the Landau gauge ghost propagator is investigated in pure SU(3) Yang-Mills theory with lattice QCD simulations. Its behavior around the confined-decon…
The quark propagator and quark-gluon vertex from lattice QCD at finite temperature
Jesuel Marques, Gerhard Kalusche, Tereza Mendes +3
The quark-gluon vertex is an important object of QCD. Studies have shown that this quantity is relevant for the dynamical chiral symmetry breaking pattern in the vacuum. The goal o…
Deconfinement in pure gauge SU(3) Yang-Mills theory: the ghost propagator
Orlando Oliveira, Vítor Paiva, Paulo Silva
The ghost propagator in Landau gauge is studied at finite temperature below and above using lattice QCD simulations. For high temperatures, we find that the ghost propagator…
