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…
Analytic structure of the gluon and quark propagators in Landau gauge QCD
R. Alkofer, W. Detmold, C. S. Fischer +1
In Landau gauge QCD the infrared behavior of the propagator of transverse gluons can be analytically determined to be a power law from Dyson-Schwinger equations. This propagator cl…
Non-perturbative Propagators, Running Coupling and Dynamical Mass Generation in Ghost-Antighost Symmetric Gauges in QCD
Christian S. Fischer
We present approximate non-perturbative solutions for the propagators as well as the running coupling of QCD from a coupled system of renormalised, truncated Dyson--Schwinger equat…
On the infrared behaviour of Gluons and Ghosts in Ghost-Antighost symmetric gauges
R. Alkofer, C. S. Fischer, H. Reinhardt +1
To investigate the possibility of a ghost-antighost condensate the coupled Dyson--Schwinger equations for the gluon and ghost propagators in Yang--Mills theories are derived in gen…
Kugo-Ojima confinement and QCD Green's functions in covariant gauges
Reinhard Alkofer, Christian S. Fischer, Lorenz von Smekal
In Landau gauge QCD the Kugo-Ojima confinement criterion and its relation to the infrared behaviour of the gluon and ghost propagators are reviewed. It is demonstrated that the rea…
Kugo-Ojima confinement criterion, Zwanziger-Gribov horizon condition, and infrared critical exponents in Landau gauge QCD
Reinhard Alkofer, Christian S. Fischer, Lorenz von Smekal
The Kugo-Ojima confinement criterion and its relation to the infrared behaviour of the gluon and ghost propagators in Landau gauge QCD are reviewed. The realization of this confine…
