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…
Determining the glue component of the nucleon
R. Horsley, T. Howson, W. Kamleh +7
Computing the gluon component of momentum in the nucleon is a difficult and computationally expensive problem, as the matrix element involves a quark-line-disconnected gluon operat…
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…
