Nucleon and Distribution Amplitudes
V. M. Braun, S. Collins, M. Göckeler +10
The QCDSF collaboration has investigated the distribution amplitudes and wavefunction normalization constants of the nucleon and its parity partner, the . We report on…
Lattice Investigations of Nucleon Structure at Light Quark Masses
M. Göckeler, Ph. Hägler, R. Horsley +7
Lattice simulations of hadronic structure are now reaching a level where they are able to not only complement, but also provide guidance to current and forthcoming experimental pro…
Extracting the rho resonance from lattice QCD simulations at small quark masses
M. Göckeler, R. Horsley, Y. Nakamura +4
Using established relations between the scattering matrix in infinite volume and the two-particle spectrum in a periodic box, we compute the mass and width of the rho meson from si…
The operator product expansion on the lattice
W. Bietenholz, N. Cundy, M. Göckeler +8
We investigate the Operator Product Expansion (OPE) on the lattice by directly measuring the product <Jmu Jnu> (where J is the vector current) and comparing it with the expectation…
The spin structure of the Lambda hyperon in quenched lattice QCD
M. Göckeler, R. Horsley, D. Pleiter +4
It has been suggested to use the production of Lambda hyperons for investigating the nucleon spin structure. The viability of this idea depends crucially on the spin structure of t…
Resolving Exceptional Configurations in Quenched Lattice QCD
M. Göckeler, A. Hoferichter, R. Horsley +4
Quenched lattice QCD calculations with Wilson-type fermions at small quark masses are impeded by exceptional configurations. We show how this problem can be resolved in a practicab…
