Bjorken sum rule down to the elastic region from the lattice
J. A. Crawford, A. Hannaford-Gunn, R. Horsley +6
We present a lattice determination of the Bjorken sum rule via a Feynman-Hellmann calculation of the polarised forward Compton amplitude. We evaluate the lowest moment of the nucle…
Towards nucleon structure function moments and parton momentum fractions from lattice QCD
K. U. Can, R. Horsley, P. E. L. Rakow +4
We calculate the lowest even isovector moment of the structure function in -flavour lattice QCD with varying quark masses corresponding to $m_π\approx [410, 360, 300] \;…
Renormalisation Group Equations for 2+1 clover fermions
K. U. Can, R. Horsley, P. E. L. Rakow +4
Many lattice QCD simulations now have many lattice spacings available, and it is of interest to investigate how they scale. In this talk we first derive renormalisation group equat…
Lattice QCD calculation of the Compton amplitude subtraction function
K. U. Can, A. Hannaford-Gunn, R. Horsley +6
The Compton amplitude subtraction function is an essential component in work concerning both the proton radius puzzle and the proton-neutron mass difference. However, owing to the…
Reconstructing generalised parton distributions from the lattice off-forward Compton amplitude
A. Hannaford-Gunn, K. U. Can, J. A. Crawford +6
We present a determination of the structure functions of the off-forward Compton amplitude and from the Feynman-Hellmann method in lattice QCD. At l…
Moments and power corrections of longitudinal and transverse proton structure functions from lattice QCD
M. Batelaan, K. U. Can, A. Hannaford-Gunn +8
We present a simultaneous extraction of the moments of and structure functions of the proton for a range of photon virtuality, . This is achieved by computing the…
Advances in lattice hadron physics calculations using the gradient flow
K. U. Can, R. Horsley, Y. Nakamura +6
Lattice calculations of hadronic observables are aggravated by short-distance fluctuations. The gradient flow, which can be viewed as a particular realisation of the coarse-grainin…
Parton distributions and lattice QCD calculations: a community white paper
Huey-Wen Lin, Emanuele R. Nocera, Fred Olness +29
In the framework of quantum chromodynamics (QCD), parton distribution functions (PDFs) quantify how the momentum and spin of a hadron are divided among its quark and gluon constitu…
