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…
New results for non-perturbative order(a) improvement in light hadrons
M. Goeckeler, R. Horsley, H. Perlt +4
We have results from light hadron simulations in quenched QCD at beta=6.0 and 6.2 using non-perturbatively improved Sheikholeslami-Wohlert fermions in an effort to remove all order…
Improvement of Nucleon Matrix Elements
S. Capitani, M. Goeckeler, R. Horsley +7
We report on preliminary results of a high statistics quenched lattice QCD calculation of nucleon matrix elements within the Symanzik improvement programme. Using the recently dete…
Perturbative Renormalization of Improved Lattice Operators
S. Capitani, M. Goeckeler, R. Horsley +4
We derive bases of improved operators for all bilinear quark currents up to spin two (including the operators measuring the first moment of DIS Structure Functions), and compute th…
Scaling of Non-Perturbatively O(a) Improved Wilson Fermions: Hadron Spectrum, Quark Masses and Decay Constants
M. Göckeler, R. Horsley, H. Perlt +4
We compute the hadron mass spectrum, the quark masses and the meson decay constants in quenched lattice QCD with non-perturbatively improved Wilson fermions. The calculation…
Pion and Rho Structure Functions from Lattice QCD
C. Best, M. Göckeler, R. Horsley +7
We calculate the lower moments of the deep-inelastic structure functions of the pion and the rho meson on the lattice. Of particular interest to us are the spin-dependent structure…
