The Lattice Calculation of Moments of Structure Functions
R. Horsley
Some aspects of recent QCDSF-UKQCD nucleon moments of structure function computations (both quenched and unquenched) are reviewed in an effort to explore the light quark mass regim…
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…
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…
