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…

Feynman--Hellmann approach to transition matrix elements and quasi-degenerate energy states
M. Batelaan, K. U. Can, R. Horsley +6
The Feynman--Hellmann approach to computing matrix elements in lattice QCD by first adding a perturbing operator to the action is described using the transition matrix and the Dyso…

Constraining beyond the Standard Model nucleon isovector charges
R. E. Smail, M. Batelaan, R. Horsley +8
At the TeV scale, low-energy precision observations of neutron characteristics provide unique probes of novel physics. Precision studies of neutron decay observables are susceptibl…
