Improving the electromagnetic form factor of the pion at large using the Feynman-Hellmann theorem
K. U. Can, J. A. Crawford, R. Horsley +7
At large momentum transfer, it becomes increasingly difficult to access the form factor of the pion using lattice QCD simulations. Two of the limiting factors include th…
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…
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…
