Generalised Parton Distributions from Lattice Feynman-Hellmann Techniques
Alec Hannaford-Gunn, Kadir Utku Can, Roger Horsley +6
We report on the use of Feynman-Hellmann techniques to calculate the off-forward Compton amplitude (OFCA) in lattice QCD. At leading-twist, the Euclidean OFCA is parameterised by t…
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…
Partially conserved axial vector current and applications
R. Horsley, S. Kazmin, Y. Nakamura +5
We investigate implications of the use of the point-split axial vector current derived from a Wilson like fermionic action. We compute the corresponding renormalization factor nonp…
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…
Extracting the rho resonance from lattice QCD simulations at small quark masses
M. Göckeler, R. Horsley, Y. Nakamura +4
Using established relations between the scattering matrix in infinite volume and the two-particle spectrum in a periodic box, we compute the mass and width of the rho meson from si…
