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…

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…
