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…
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…
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…
Investigating the Compton amplitude subtraction function in lattice QCD
Alec Hannaford-Gunn, Edward Sankey, Kadir Utku Can +8
Theoretical predictions of the proton--neutron mass difference and measurements of the proton's charge radius require inputs from the Compton amplitude subtraction function. Model-…
Generalised Parton Distributions from Lattice Feynman-Hellmann Techniques
Alec Hannaford-Gunn, Kadir Utku Can, Roger Horsley +6
We report on the use of Feynman-Hellmann techniques to calculate the off-forward Compton amplitude (OFCA) in lattice QCD. At leading-twist, the Euclidean OFCA is parameterised by t…
