Studying unquenching effects in QCD with Dyson-Schwinger equations
Christian S. Fischer, Reinhard Alkofer, Wolfgang Cassing +2
We summarise recent results on the properties of gluons, quarks and light mesons from the Green's functions approach to QCD. We discuss a self-consistent, infrared power law soluti…
Aspects of the confinement mechanism in Coulomb-gauge QCD
R. Alkofer, M. Kloker, A. Krassnigg +1
Phenomenological consequences of the infrared singular, instantaneous part of the gluon propagator in Coulomb gauge are investigated. The corresponding quark Dyson-Schwinger equati…
Partial-wave decomposition of the Faddeev amplitude of a Poincaré-invariant three-fermion bound state
Reinhard Alkofer, Martin Oettel
A partial-wave decomposition of the Faddeev amplitude of a Poincare-invariant three-fermion bound state is presented. Some implications for the properties of the nucleon as relativ…
Solving coupled Dyson--Schwinger equations on a compact manifold
C. S. Fischer, B. Gruter, R. Alkofer
We present results for the gluon and ghost propagators in SU(N) Yang--Mills theory on a four-torus at zero and nonzero temperatures from a truncated set of Dyson-Schwinger equation…
The High-Temperature Phase of Landau-Gauge Yang-Mills Theory
Axel Maas, Jochen Wambach, Reinhard Alkofer
The properties of the high-temperature phase of Yang-Mills theory in Landau gauge are investigated by extending an earlier study on the infinite-temperature limit to finite tempera…
