Dynamical Chiral Symmetry Breaking in Landau gauge QCD
C. S. Fischer, R. Alkofer
We summarise results for the propagators of Landau gauge QCD from the Green's functions approach and lattice calculations. The nonperturbative solutions for the ghost, gluon and qu…
Finite-Temperature Yang-Mills Theory in Landau Gauge
Axel Maas, Jochen Wambach, Burghard Gruter +1
The gluon and ghost propagators in Landau Gauge Yang-Mills Theory are investigated. Self-consistent solutions are obtained from their equations of motion above and below the presum…
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…
Residual Confinement in High-Temperature Yang-Mills Theory
Axel Maas, Jochen Wambach, Burghard Gruter +1
The infrared behavior of Landau gauge gluon and ghost propagators are investigated in Yang-Mills theory at non-vanishing temperatures. Self-consistent solutions are presented for t…
High-Temperature Limit of Landau-Gauge Yang-Mills Theory
Axel Maas, Jochen Wambach, Burghard Gruter +1
The infrared properties of the high-temperature limit of Landau-gauge Yang-Mills theory are investigated. In a first step the high-temperature limit of the Dyson-Schwinger equation…
Temperature Dependence of Gluon and Ghost Propagators in Landau-Gauge Yang-Mills Theory below the Phase Transition
Burghard Gruter, Reinhard Alkofer, Axel Maas +1
The Dyson-Schwinger equations of Landau-gauge Yang-Mills theory for the gluon and ghost propagators are investigated. Numerical results are obtained within a truncation scheme whic…
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,…
Dynamical Mass Generation in Landau gauge QCD
C. S. Fischer, F. Llanes-Estrada, R. Alkofer
We summarise results on the infrared behaviour of Landau gauge QCD from the Green's functions approach and lattice calculations. Approximate, nonperturbative solutions for the ghos…
Dynamical Chiral Symmetry Breaking in Unquenched
C. S. Fischer, R. Alkofer, T. Dahm +1
We investigate dynamical chiral symmetry breaking in unquenched using the coupled set of Dyson--Schwinger equations for the fermion and photon propagators. For the fermio…
QCD Propagators at non-vanishing temperatures
B. Gruter, R. Alkofer, A. Maas +1
We investigate the behaviour of the gluon and ghost propagators, especially their infrared properties, at non-vanishing temperatures. To this end we solve their Dyson-Schwinger equ…
