Aspects of gluon propagation in Landau gauge: spectral densities, and mass scales at finite temperature
Paulo J. Silva, Orlando Oliveira, David Dudal +2
We discuss a method to extract the Källén-Lehmann spectral density of a particle (be it elementary or bound state) propagator and apply it to compute gluon spectral densities from…
On bounds and boundary conditions in the continuum Landau gauge
D. Dudal, M. S. Guimaraes, I. F. Justo +1
In this note, we consider the Landau gauge in the continuum formulation. Our purposes are twofold. Firstly, we try to work out the consequences of the recently derived Cucchieri-Me…
Evidence of BRST-Symmetry Breaking in Lattice Minimal Landau Gauge
Attilio Cucchieri, David Dudal, Tereza Mendes +1
By evaluating the so-called Bose-ghost propagator, we present the first numerical evidence of BRST-symmetry breaking for Yang-Mills theory in minimal Landau gauge, i.e. due to the…
The melting of charmonium in a magnetic field from an effective AdS/QCD model
David Dudal, Thomas G. Mertens
We study the influence of a background magnetic field on the melting of the J/psi vector meson by introducing a Born-Infeld modification of the soft-wall model. Out of the three po…
BRST-Symmetry Breaking and Bose-Ghost Propagator in Lattice Minimal Landau Gauge
Attilio Cucchieri, David Dudal, Tereza Mendes +1
The Bose-ghost propagator has been proposed as a carrier of the confining force in Yang-Mills theories in minimal Landau gauge. We present the first numerical evaluation of this pr…
Many faces of the Landau gauge gluon propagator at zero and finite temperature: positivity violation, spectral density and mass scales
Paulo J. Silva, Orlando Oliveira, David Dudal +2
We address several aspects of gluon propagation at zero and finite temperature. In particular, we study the violation of spectral positivity, we discuss a method to extract the Käl…
