Nucleon Structure from Quenched Overlap Fermions
D. Galletly, M. Gürtler, R. Horsley +6
We compute the lowest moments of the nucleon's structure functions using quenched overlap fermions at two different lattice spacings. The renormalisation is done nonperturbatively…
A lattice determination of g_A and <x> from overlap fermions
M. Gürtler, R. Horsley, V. Linke +5
We present results for the nucleon's axial charge g_A and the first moment <x> of the unpolarized parton distribution function from a simulation of quenched overlap fermions.
Low-Lying Fermion Modes: Dynamical versus Quenched
R. Horsley, T. G. Kovacs, V. Linke +3
We compare the low-lying eigenmodes of the O(a) improved Wilson-Dirac operator on quenched and dynamical configurations and investigate methods of probing the topological propertie…
Low-lying fermion modes of Nf=2 improved Wilson fermions
R. Horsley, T. G. Kovacs, V. Linke +2
We present preliminary results for the topological charge and susceptibility determined from the low-lying eigenmodes of the Wilson-Dirac operator. These modes have been computed o…
The Vacuum Polarization: Power Corrections beyond OPE ?
M. Gockeler, R. Horsley, W. Kurzinger +4
We compute the vacuum polarization on the lattice using non-perturbatively O(a) improved Wilson fermions. The result is compared with the operator product expansion (OPE).
Higher-twist contributions to the Structure Functions coming from 4-fermion operators
S. Capitani, M. Göckeler, R. Horsley +5
We evaluate the contribution of a class of higher-twist operators to the lowest moment of the Structure Functions, by computing appropriate matrix elements of six four-fermion oper…
