The Landau gauge lattice ghost propagator in stochastic perturbation theory
F. Di Renzo, E. -M. Ilgenfritz, H. Perlt +2
We present one- and two-loop results for the ghost propagator in Landau gauge calculated in Numerical Stochastic Perturbation Theory (NSPT). The one-loop results are compared with…

Smearing and filtering methods in lattice QCD - a quantitative comparison
Stefan Solbrig, Falk Bruckmann, Christof Gattringer +3
We systematically compare three filtering methods used to extract topological excitations from lattice gauge configurations, namely smearing, Laplace filtering and the filtered fer…
