Improvement for Quenched Wilson Fermions
S. Capitani, M. Goeckeler, R. Horsley +9
We briefly describe some of our recent results for the mass spectrum and matrix elements using improved fermions for quenched QCD. Where possible a comparison is made betwee…
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…
Polarized Nucleon Structure Functions from Lattice QCD
M. Goeckeler, R. Horsley, E. -M. Ilgenfritz +4
We describe a high statistics quenched QCD calculation of the moments of the polarized deep-inelastic structure functions g_1 and g_2 of the proton and neutron.
