Recent Results on the Nucleon Structure Functions from Lattice QCD
M. Göckeler, R. Horsley, E. -M. Ilgenfritz +5
We report on recent results of a high statistics lattice calculation of the unpolarized and polarized structure functions of the nucleon.
Non-Perturbative versus Perturbative Renormalization of Lattice Operators
M. Göckeler, R. Horsley, E. -M. Ilgenfritz +5
Our objective is to compute the moments of the deep-inelastic structure functions of the nucleon on the lattice. A major source of uncertainty is the renormalization of the lattice…
Scattering phases for fermion-fermion scattering in the Gross-Neveu model
M. Goeckeler, H. A. Kastrup, J. Viola +1
We extract scattering phases for fermion-fermion scattering from Monte Carlo simulations of the two-dimensional Gross-Neveu model. This is done by means of Lüscher's method, which…
Polarized and Unpolarized Nucleon Structure Functions from Lattice QCD
M. Göckeler, R. Horsley, E. -M. Ilgenfritz +4
We report on a high statistics quenched lattice QCD calculation of the deep-inelastic structure functions , , and of the proton and neutron. The theoretical b…
Hadronic Coupling Constants in Lattice QCD
R. L. Altmeyer, M. Gockeler, R. Horsley +3
We calculate the hadronic coupling constants and in QCD, including dynamical quarks in the framework of staggered fermions in the lattice approach. For the nucl…
Effective Yukawa Couplings in Noncompact Lattice QED
M. Goeckeler, R. Horsley, P. E. L. Rakow +1
We investigate effective Yukawa couplings of mesons to the elementary fermions in noncompact lattice QED. The couplings are extracted from suitable fermion-antifermion-meson three-…
