Lattice Landau gauge via Stereographic Projection
Lorenz von Smekal, Alexander Jorkowski, Dhagash Mehta +1
The complete cancellation of Gribov copies and the Neuberger 0/0 problem of lattice BRST can be avoided in modified lattice Landau gauge. In compact U(1), where the problem is a la…
Landau Gauge QCD: Functional Methods versus Lattice Simulations
Lorenz von Smekal
The infrared behaviour of QCD Green's functions in Landau gauge has been focus of intense study. Different non-perturbative approaches lead to a prediction in line with the conditi…
Decontracted double BRST on the lattice
Lorenz von Smekal, Marco Ghiotti, Anthony G Williams
We present the Curci-Ferrari model on the lattice. In the massless case the topological interpretation of this model with its double BRST symmetry relates to the Neuberger 0/0 prob…
Signatures of confinement in Landau gauge QCD
J. M. Pawlowski, D. F. Litim, S. Nedelko +1
We summarise an analysis of the infrared regime of Landau gauge QCD by means of a flow equation approach. The infrared behaviour of gluon and ghost propagators is evaluated. The re…
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…
