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…
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…
Renormalization flow of Yang-Mills propagators
Christian S. Fischer, Holger Gies
We study Landau-gauge Yang-Mills theory by means of a nonperturbative vertex expansion of the quantum effective action. Using an exact renormalization group equation, we compute th…
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…
