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…
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…
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…
Nucleon Form Factors from the Feynman-Hellmann Method in Lattice QCD
M. Batelaan, R. Horsley, Y. Nakamura +7
Lattice QCD calculations of the nucleon electromagnetic form factors are of interest at both the high and low momentum transfer regions. For high momentum transfers especially ther…
