The QED photon-fermion vertex from its Dyson-Schwinger equation in 4D: the full vertex, the transverse form factors and the perturbative solution
Orlando Oliveira
We investigate the Dyson-Schwinger equation for the photon-fermion one-particle irreducible vertex in QED in linear covariant gauges. The longitudinal component of this vertex is d…
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…
Four Gluon Vertex from Lattice QCD
Manuel Colaço, Orlando Oliveira, Paulo J. Silva
A lattice QCD calculation for the four gluon one-particle irreducible Green function in the Landau gauge is discussed. Results for some of the associated form factors are reported…
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…
Lattice QCD static potentials of the meson-meson and tetraquark systems computed with both quenched and full QCD
P. Bicudo, M. Cardoso, O. Oliveira +1
We revisit the static potential for the system using SU(3) lattice simulations, studying both the colour singlets groundstate and first excited state. We consid…
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…
