Effective field theory of scalar glueballs: Form factors and interaction radii

Adamu Issifu, Orlando Oliveira, Tobias Frederico

We develop a gauge-invariant effective field theory for scalar glueball interactions based on the Yang-Mills gluon condensate. Starting from a coherent-state formulation of the Yan…

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…

Compact QED: the photon propagator, confinement and positivity violation for the pure gauge theory

Orlando Oliveira, Lee C. Loveridge, Paulo J. Silva

The lattice Landau gauge photon propagator for the pure gauge theory is revisited using large lattices. For the confined case we show that it has an associated linearly growing pot…

The analytic structure of the Landau gauge quark propagator from Padé analysis

Alexandre F. Falcão, Orlando Oliveira

The analytic structure of the 2 flavour full QCD lattice Landau gauge quark propagator is investigated with Padé approximants applied to its vector and scalar form factors. No pole…
