Excited nucleon spectrum using a non-perturbatively improved clover fermion action
LHPC Collaboration, D. G. Richards, QCDSF Collaboration +8
We discuss the extraction of negative-parity baryon masses from lattice QCD calculations. The mass of the lowest-lying negative-parity state is computed in quenched l…
The strong coupling constant from lattice QCD with N_f=2 dynamical quarks
S. Booth, M. Göckeler, R. Horsley +8
We compute for two flavors of light dynamical quarks using non-perturbatively improved Wilson fermions. We improve on a recent calculation by employing Padé-i…
Progress towards a lattice determination of (moments of) nucleon structure functions
S. Capitani, M. Gockeler, R. Horsley +4
Using unimproved and non-perturbatively O(a) improved Wilson fermions, results are given for the three lowest moments of unpolarised nucleon structure functions. Renormalisation, c…
Separating perturbative and non-perturbative contributions to the plaquette
R. Horsley, P. E. L. Rakow, G. Schierholz
We try to separate the perturbative and non-perturbative contributions to the plaquette of pure SU(3) gauge theory. To do this we look at the large-n asymptotic behaviour of the pe…
Lattice QCD at finite temperature: Evidence for calorons from the eigenvectors of the Dirac operator
C. Gattringer, M. Göckeler, P. E. L. Rakow +3
We analyze the eigenvalues and eigenvectors of the staggered Dirac operator in quenched lattice QCD in the vicinity of the deconfinement phase transition using the Lüscher-Weisz ga…
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…
