A status report of the QCDSF Project
Meinulf Göckeler, Roger Horsley, Yoshifumi Nakamura +8
We report about on-going simulations of lattice QCD. We use a tadpole improved Symanzik gauge action and stout link smeared Wilson fermions with a clover term. We employ…
Probing the chiral limit with clover fermions II: The baryon sector
M. Göckeler, Philipp Hägler, R. Horsley +9
Algorithmic progress in recent years made it possible to simulate QCD with Nf=2 flavours of O(a)-improved Wilson fermions at very light quark masses. We present the current results…
Distribution Amplitudes of Vector Mesons
V. M. Braun, D. Brömmel, M. Göckeler +12
Results are presented for the lowest moment of the distribution amplitude for the K-star vector meson. Both longitudinal and transverse moments are investigated. We use two flavour…
Nucleon electromagnetic form factors with Wilson fermions
M. Gockeler, Ph. Hagler, R. Horsley +9
The nucleon electromagnetic form factors continue to be of major interest for experimentalists and phenomenologists alike. They provide important insights into the structure of nuc…
Kaon semileptonic decay form factors from N_f = 2 non-perturbatively O(a)-improved Wilson fermions
QCDSF Collaboration, D. Brommel, R. Horsley +6
We present first results from the QCDSF collaboration for the kaon semileptonic decay form factors at zero momentum transfer, using two flavours of non-perturbatively O(a)-improved…
Perturbative determination of with Symanzik improved gauge action and stout smearing
R. Horsley, H. Perlt, P. E. L. Rakow +2
We determine the improvement factor in one-loop lattice perturbation theory for the plaquette and Symanzik improved gauge actions. The fermionic action is ${\mathcal{O}(a)…
