The four-gluon vertex and the running coupling in Landau gauge Yang-Mills theory
Christian Kellermann, Christian S. Fischer
We summarise results for 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…

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…

Analytic structure of the Landau gauge gluon propagator
R. Alkofer, W. Detmold, C. S. Fischer +1
The results of different non-perturbative studies agree on a power law as the infrared behavior of the Landau gauge gluon propagator. This propagator violates positivity and thus i…
