Transverse force distributions in the proton from lattice QCD
J. A. Crawford, K. U. Can, R. Horsley +5
Single-spin asymmetries observed in polarised deep-inelastic scattering are important probes of hadron structure. The Sivers asymmetry has been the focus of much attention in QCD p…
Patterns of flavour symmetry breaking in hadron matrix elements involving u, d and s quarks
J. M. Bickerton, R. Horsley, Y. Nakamura +7
By considering a flavour expansion about the SU(3)-flavour symmetric point, we investigate how flavour-blindness constrains octet baryon matrix elements after SU(3) is broken by th…
Nucleon and Distribution Amplitudes
V. M. Braun, S. Collins, M. Göckeler +10
The QCDSF collaboration has investigated the distribution amplitudes and wavefunction normalization constants of the nucleon and its parity partner, the . We report on…
Lattice Investigations of Nucleon Structure at Light Quark Masses
M. Göckeler, Ph. Hägler, R. Horsley +7
Lattice simulations of hadronic structure are now reaching a level where they are able to not only complement, but also provide guidance to current and forthcoming experimental pro…
The operator product expansion on the lattice
W. Bietenholz, N. Cundy, M. Göckeler +8
We investigate the Operator Product Expansion (OPE) on the lattice by directly measuring the product <Jmu Jnu> (where J is the vector current) and comparing it with the expectation…
Simulating at Realistic Quark Masses: Light quark masses
M. Göckeler, R. Horsley, Y. Nakamura +6
We present new results for light quark masses. The calculations are performed using two flavours of improved Wilson fermions. We have reached lattice spacings as small as $a…
