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…
Z(N) dependence of the pure Yang-Mills gluon propagator in the Landau gauge near Tc
Orlando Oliveira, Paulo J. Silva
The Z(N) dependence of the pure Yang-Mills gluon propagator, in the Landau gauge, is investigated at finite temperature for N=3. Special attention will be given to the behaviour ne…
Gluon mass at finite temperature in Landau gauge
Pedro Bicudo, Orlando Oliveira, Paulo Silva +1
Using lattice results for the Landau gauge gluon propagator at finite temperature, we investigate its interpretation as a massive type bosonic propagator. In particular, we estimat…
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…
