The Compton amplitude and nucleon structure functions in lattice QCD
K. U. Can, M. Batelaan, A. Hannaford-Gunn +8
The structure of hadrons relevant for deep-inelastic scattering are completely characterised by the Compton amplitude. A direct calculation of the Compton amplitude in a lattice QC…
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…
Weak decay constants of the neutral pseudoscalar mesons from lattice QCD+QED
Z. R. Kordov, R. Horsley, W. Kamleh +7
With increasing requirements for greater precision, it becomes essential to describe the effects of isospin breaking induced by both quark masses and electro-magnetic effects. In t…
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…
Quasi-degenerate baryon energy states, the Feynman--Hellmann theorem and transition matrix elements
M. Batelaan, K. U. Can, R. Horsley +7
The standard method for determining matrix elements in lattice QCD requires the computation of three-point correlation functions. This has the disadvantage of requiring two large t…
