Perturbative subtraction of lattice artifacts in the computation of renormalization constants
M. Constantinou, M. Costa, M. Gockeler +6
The determination of renormalization factors is of crucial importance. They relate the observables obtained on finite, discrete lattices to their measured counterparts in the conti…
Baryon Axial Charges and Momentum Fractions with N_f=2+1 Dynamical Fermions
M. Göckeler, Ph. Hägler, R. Horsley +8
We report on recent results of the QCDSF/UKQCD Collaboration on investigations of baryon structure using configurations generated with N_f=2+1 dynamical flavours of O(a) improved W…
Non-perturbative improvement of stout-smeared three flavour clover fermions
N. Cundy, M. Göckeler, R. Horsley +11
We discuss a 3-flavour lattice QCD action with clover improvement in which the fermion matrix has single level stout smearing for the hopping terms together with unsmeared links fo…
Hadronic structure from the lattice
Dirk Brommel, Meinulf Gockeler, Philipp Hagler +10
In recent years the investigation of hadron structure using lattice techniques has attracted growing attention. In this talk we give an overview on recent work with a focus on resu…
Nucleon distribution amplitudes from lattice QCD
Meinulf Göckeler, Roger Horsley, Thomas Kaltenbrunner +8
We calculate low moments of the leading-twist and next-to-leading twist nucleon distribution amplitudes on the lattice using two flavors of clover fermions. The results are present…
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…
