Using the Landau gauge gluon propagator to set the lattice physical scales and understanding the finite size effects
Orlando Oliveira, Paulo J Silva
A crucial step in extracting physical predictions from lattice QCD simulations is the scale setting, i.e. the determination of the lattice spacing () in physical units. Herein,…
The four-gluon and ghost-gluon vertices in the Landau gauge from lattice simulations
Nuno Brito, Manuel Colaço, Orlando Oliveira +1
The computation of the four-gluon and ghost-gluon vertices in the Landau gauge using high statistical lattice ensembles for and volumes is addressed. For the four-glu…
Center-symmetric Landau gauge, the deconfinement transition and the gluon propagator as seen in lattice QCD
Duifje Maria van Egmond, Orlando Oliveira, Urko Reinosa +3
We address the lattice computation of the gluon propagator in the center-symmetric Landau gauge. After discussing a proper lattice implementation of the center-symmetric Landau gau…
The four-gluon vertex from lattice QCD
Manuel Colaço, Orlando Oliveira, Paulo J. Silva
The four-gluon one-particle irreducible Green function contributes to various quantities with phenomenological relevance. An example where the four-gluon plays a role is the determ…
The center-symmetric Landau gauge meets the lattice
Duifje Maria van Egmond, Orlando Oliveira, Urko Reinosa +3
A lattice implementation of the recently introduced center-symmetric Landau gauge is discussed and its predictions confronted with numerical Monte Carlo simulations. It is shown th…
High statistical computation of the Landau gauge ghost-gluon vertex
Nuno Brito, Orlando Oliveira, Paulo J. Silva
The lattice computation of the one-particle irreducible ghost-gluon Green function in the Landau gauge is revisited with a set of large gauge ensembles. The large statistical ensem…
