Setting the scale for the Luescher-Weisz action
Christof Gattringer, Roland Hoffmann, Stefan Schaefer
We study the quark-antiquark potential of quenched SU(3) lattice gauge theory with the Luescher-Weisz action. After blocking the gauge fields with the recently proposed hypercubic…
Chirally improved Dirac operators: Studying the sensitivity to topological excitations for zero and finite temperature
Christof Gattringer, Meinulf Göckeler, C. B. Lang +3
We discuss the construction and properties of an approximate solution of the Ginsparg-Wilson equation, the so-called chirally improved lattice Dirac operator. In particular we stud…
Properties of near-zero modes and chiral symmetry breaking
Christof Gattringer, Meinulf Goeckeler, P. E. L. Rakow +2
We study localization and chirality properties of eigenvectors of the lattice Dirac operator. In particular we focus on the dependence of our observables on the size of the corresp…
A comprehensive picture of topological excitations in finite temperature lattice QCD
Christof Gattringer, Meinulf Göckeler, P. E. L. Rakow +2
We study spectra, localization properties and local chirality of eigenvectors of the lattice Dirac operator. We analyze ensembles of quenched SU(3) configurations on both sides of…
A lattice evaluation of four-quark operators in the nucleon
M. Göckeler, R. Horsley, B. Klaus +5
Nucleon matrix elements of various four-quark operators are evaluated in quenched lattice QCD using Wilson fermions. Some of these operators give rise to twist-four contributions t…
