Is there a Landau Pole Problem in QED?
M. Göckeler, R. Horsley, V. Linke +3
We investigate a lattice version of QED by numerical simulations. For the renormalized charge and mass we find results which are consistent with the renormalized charge vanishing i…
Spin Structure Functions from Lattice QCD
M. Göckeler, R. Horsley, H. Perlt +4
We report on new results of the spin dependent structure functions and of the nucleon. An attempt is made to convert the moments, which is what one computes on the latt…
Local bilinear operators on the lattice and their perturbative renormalisation including O(a) effects
S. Capitani, M. Göckeler, R. Horsley +4
Some basic concepts are discussed to derive renormalisation factors of local lattice operators relevant to deep inelastic structure functions and to other measurable quantities. Th…
Lattice Renormalization of Quark Operators
M. Goeckeler, R. Horsley, H. Oelrich +4
We have technically improved the non-perturbative renormalization method, proposed by Martinelli et al., by using quark momentum sources and sinks. Composite two-fermion operators…
The Deep-Inelastic Structure Functions of and Mesons
C. Best, M. Göckeler, R. Horsley +6
We compute the lower moments of the structure functions of and . Of particular interest are the spin-dependent structure functions of the as they give new information ab…
Non-perturbative improvement and renormalization of lattice operators
S. Capitani, M. Goeckeler, R. Horsley +7
The Alpha Collaboration has proposed an optimal value for c_SW in the Sheikholeslami-Wohlert action, chosen to remove O(a) effects. To measure hadronic matrix elements to the same…
