What Does Low Energy Physics Tell Us About The Zero Momentum Gluon Propagator
Pedro Costa, O. Oliveira, P. J. Silva
The connection between QCD, a nonlocal Nambu--Jona-Lasinio type model and the Landau gauge gluon propagator is explored. This two point function is parameterized by a functional fo…

Gauge fixing methods and Gribov copies effects in lattice QCD
P. J. Silva, O. Oliveira
We compare two Landau gauge fixing methods, aiming to find the global maximum of the gauge fixing functional. Moreover, a systematic effect of Gribov copies in the gluon and ghost…

First study of the gluon-quark-antiquark static potential in SU(3) Lattice QCD
P. Bicudo, M. Cardoso, O. Oliveira
We study the long distance interaction for hybrid hadrons, with a static gluon, a quark and an antiquark with lattice QCD techniques. A Wilson loop adequate to the static hybrid th…
