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-…
Lattice QCD evaluation of the Compton amplitude employing the Feynman-Hellmann theorem
K. U. Can, A. Hannaford-Gunn, R. Horsley +8
The forward Compton amplitude describes the process of virtual photon scattering from a hadron and provides an essential ingredient for the understanding of hadron structure. As a…
Structure functions from the Compton amplitude
CSSM collaboration, Roger Horsley, Yoshifumi Nakamura +6
We have initiated a program to compute the Compton amplitude from lattice QCD with the Feynman-Hellman method. This amplitude is related to the structure function via a Fredholm in…
Scaling and higher twist in the nucleon Compton amplitude
A. Hannaford-Gunn, R. Horsley, Y. Nakamura +7
The partonic structure of hadrons plays an important role in a vast array of high-energy and nuclear physics experiments. It also underpins the theoretical understanding of hadron…
Nucleon structure functions from lattice operator product expansion
A. J. Chambers, R. Horsley, Y. Nakamura +7
Deep-inelastic scattering, in the laboratory and on the lattice, is most instructive for understanding how the nucleon is built from quarks and gluons. The long-term goal is to com…
Electromagnetic form factors at large momenta from lattice QCD
A. J. Chambers, J. Dragos, R. Horsley +10
Accessing hadronic form factors at large momentum transfers has traditionally presented a challenge for lattice QCD simulations. Here we demonstrate how a novel implementation of t…
