Glueballs from the Bethe-Salpeter equation
Helios Sanchis-Alepuz, Christian S. Fischer, Christian Kellermann +1
We formulate a framework to determine the mass of glueball states of Landau gauge Yang-Mills theory in the continuum. To this end we derive a Bethe-Salpeter equation for two gluon…
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…
