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…
Hot electroweak matter near to the endpoint of the phase transition
M. Gürtler, E. -M. Ilgenfritz, A. Schiller +1
The electroweak phase transition is investigated near to its endpoint in the framework of an effective three-dimensional model. We measure the very weak interface tension with the…
