First evidence for Casimir scaling in G(2) lattice gauge theory

L. Liptak, S. Olejnik

Potentials between static quarks and antiquarks from a few lowest representations were evaluated in numerical simulations of 4-dimensional pure G lattice gauge theory at variou…

More on Gribov copies and propagators in Landau-gauge Yang-Mills theory

Axel Maas

Fixing a gauge in the non-perturbative domain of Yang-Mills theory is a non-trivial problem due to the presence of Gribov copies. In particular, there are different gauges in the n…

Casimir scaling in G(2) lattice gauge theory

L. Liptak, S. Olejnik

We computed potentials between static color sources from the six lowest representations of G(2) lattice gauge theory, in numerical simulations with the Wilson action on asymmetric…

Center Vortices and the Dirac Spectrum

Manfried Faber, Jeff Greensite, Urs M. Heller +2

We study correlations between center vortices and the low-lying eigenmodes of the Dirac operator, in both the overlap and asqtad formulations. In particular we address a puzzle rai…

Linear Covariant Gauges on the Lattice

Attilio Cucchieri, Axel Maas, Tereza Mendes

Linear covariant gauges, such as Feynman gauge, are very useful in perturbative calculations. Their nonperturbative formulation is, however, highly non-trivial. In particular, it i…

Three-point vertices in Landau-gauge Yang-Mills theory

Attilio Cucchieri, Axel Maas, Tereza Mendes

Vertices are of central importance for constructing QCD bound states out of the individual constituents of the theory, i.e. quarks and gluons. In particular, the determination of t…
