Beyond the rainbow: effects from pion back-coupling
Christian S. Fischer, Richard Williams
We investigate hadronic unquenching effects in light quarks and mesons. To this end we take into account the back-coupling of the pion onto the quark propagator within the non-pert…
The running coupling from the four-gluon vertex in Landau gauge Yang-Mills theory
Christian Kellermann, Christian S. Fischer
We consider the running coupling from the four-gluon vertex in Landau gauge, SU() Yang-Mills theory as given by a combination of dressing functions of the vertex and the gluon…
Studying pion effects in the quark propagator
Dominik Nickel, Christian S. Fischer, Jochen Wambach
Within the framework of Schwinger-Dyson and Bethe-Salpeter equations we investigate the importance of pions for the quark-gluon interaction. To this end we choose a truncation for…
Nonperturbative quark-gluon dynamics
Christian S. Fischer, Reinhard Alkofer, Felipe J. Llanes-Estrada +1
We summarize recent results on the nonperturbative quark-gluon interaction in Landau gauge QCD. Our analytical analysis of the infrared behaviour of the quark-gluon vertex reveals…
Dynamically induced scalar quark confinement: A link between chiral symmetry breaking and confinement
Reinhard Alkofer, Christian S. Fischer, Felipe J. Llanes-Estrada +1
Employing functional approaches the infrared behaviour of Landau gauge QCD vertex functions is investigated. Results for the ghost-gluon, three-gluon and quark-gluon vertex functio…
Hadronic unquenching effects in the quark propagator
Christian S. Fischer, Dominik Nickel, Jochen Wambach
We investigate hadronic unquenching effects in light quarks and mesons. Within the non-perturbative continuum framework of Schwinger-Dyson and Bethe-Salpeter equations we quantify…
