The Ghost-Gluon Vertex in Landau Gauge Yang-Mills Theory
Wolfgang Schleifenbaum, Axel Maas, Jochen Wambach +1
Possible mechanisms for gluon confinement in Yang-Mills theory in covariant gauges are discussed briefly. Implications for the infrared behavior of the Green's functions are outlin…
Infrared behaviour of the ghost-gluon vertex in Landau gauge Yang-Mills theory
Wolfgang Schleifenbaum, Axel Maas, Jochen Wambach +1
A semi-perturbative calculation of the ghost-gluon vertex in Landau gauge Yang-Mills theory in four and three Euclidean space-time dimensions is presented. Non-perturbative gluon a…
Semiperturbative construction for the quark-gluon vertex
Felipe J. Llanes-Estrada, Christian S. Fischer, Reinhard Alkofer
We construct a model for the quark-gluon vertex of Landau gauge QCD. This is of twofold interest: on the one hand the quark-gluon interaction is at the heart of quark confinement,…
The Kugo-Ojima confinement criterion and the Infrared Behavior of Landau gauge QCD
R. Alkofer, C. S. Fischer
Recent investigations of the Dyson-Schwinger equations and Monte-Carlo lattice calculations resulted in a coherent description of the fully dressed gluon, ghost and quark propagato…
Infrared Exponents and the Running Coupling of Landau gauge QCD and their Relation to Confinement
Reinhard Alkofer, Christian S. Fischer, Lorenz von Smekal
The infrared behaviour of the gluon and ghost propagators in Landau gauge QCD is reviewed. The Kugo-Ojima confinement criterion and the Gribov-Zwanziger horizon condition result fr…
The Kugo-Ojima Confinement Criterion from Dyson-Schwinger Equations
Reinhard Alkofer, Lorenz von Smekal, Peter Watson
Prerequisites of confinement in the covariant and local description of QCD are reviewed. In particular, the Kugo-Ojima confinement criterion, the positivity violations of transvers…
