Structure functions from the Compton amplitude
CSSM collaboration, Roger Horsley, Yoshifumi Nakamura +6
We have initiated a program to compute the Compton amplitude from lattice QCD with the Feynman-Hellman method. This amplitude is related to the structure function via a Fredholm in…
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…
Flavour symmetry breaking and tuning the strange quark mass for 2+1 quark flavours
W. Bietenholz, V. Bornyakov, M. Göckeler +14
QCD lattice simulations with 2+1 flavours typically start at rather large up-down and strange quark masses and extrapolate first the strange quark mass to its physical value and 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…
Kl3 and pion form factors using partially twisted boundary conditions
P. A. Boyle, J. M. Flynn, A. Jüttner +5
We compute the Kl3 and pion form factors using partially twisted boundary conditions. The twists are chosen so that the Kl3 form factors are calculated directly at zero momentum tr…
