Stochastic Perturbation Theory and the Gluon Condensate
P. E. L. Rakow
On the lattice searching for the gluon condensate is difficult because a large perturbative contribution to the expectation value of the action has to be subtracted before looking…
Quenched QCD near the chiral limit
M. Gockeler, R. Horsley, D. Petters +3
A numerical study of quenched QCD for light quarks is presented using O(a) improved fermions. Particular attention is paid to the possible existence and determination of quenched c…
The Polarized Structure Function g_2: A Lattice Study Revisited
M. Göckeler, R. Horsley, W. Kürzinger +3
A recent lattice calculation of the spin-dependent structure function g_2 is revisited. It has been recognized that the twist-three operator, which gives rise to d_2, mixes non-per…
Random Matrix Theory and Chiral Logarithms
M. E. Berbenni-Bitsch, M. Göckeler, H. Hehl +4
Recently, the contributions of chiral logarithms predicted by quenched chiral perturbation theory have been extracted from lattice calculations of hadron masses. We argue that a de…
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…
