Lattice artefacts on the Landau gauge gluon propagator from hypercubic tensor representations
Guilherme Catumba, Orlando Oliveira, Paulo J. Silva
Lattice tensor representations are used to investigate the lattice Landau gauge gluon propagator for the 4-dimensional pure SU(3) Yang-Mills gauge theory. Due to the different symm…
Quark-gluon vertex with 2 flavours of O(a) improved Wilson fermions
Ayse Kızılersü, Orlando Oliveira, Paulo Silva +2
We study the Landau-gauge quark-gluon vertex with 2 flavours of O(a)improved Wilson fermions, for several lattice spacings and quark masses. In the limit of vanishing gluon momentu…
Lattice pure gauge compact QED in the Landau gauge: the photon propagator, the phase structure and the presence of Dirac strings
Lee C. Loveridge, Orlando Oliveira, Paulo J. Silva
In this work we investigate the lattice Landau gauge photon propagator together with the average number of Dirac strings in the compact formulation of QED for the pure gauge versio…
Another look at the Landau gauge three-gluon vertex
Guilherme T. R. Catumba, Orlando Oliveira, Paulo J. Silva
We revisit the computation of the three-gluon vertex in the Landau gauge using lattice QCD simulations with large physical volumes of (6.5 fm) and (8 fm) an…
Confinement/Deconfinement in 4D compact QED on the lattice
Lee C. Loveridge, Orlando Oliveira, Paulo J. Silva
It has long been known that there is a phase transition between confined and unconfined phases of compact pure gauge QED on the lattice. In this work we report three manifestations…
Another look at the three-gluon vertex in the minimal Landau gauge
Guilherme T. R. Catumba, Orlando Oliveira, Paulo J. Silva
The lattice three-gluon vertex in the Landau gauge is revisited using a large physical volume and a large statistical ensemble. The improved calculation expl…
