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…
A Bethe--Salpeter Description of Light Mesons
H. Weigel, R. Alkofer, P. Watson
We present a covariant approach to describe the low--lying scalar, pseudoscalar, vector and axialvector mesons as quark--antiquark bound states.This approach is based on an effecti…
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…
Non-perturbative Propagators, Running Coupling and Dynamical Quark Mass of Landau gauge QCD
Christian S. Fischer, Reinhard Alkofer
The coupled system of renormalized Dyson-Schwinger equations for the quark, gluon and ghost propagators of Landau gauge QCD is solved within truncation schemes. These employ bare a…
