Skewed Parton Distributions in Real and Virtual Compton Scattering
arXiv:hep-ph/9903268 · doi:10.1016/S0370-2693(99)00759-5
Abstract
The handbag contribution to Compton scattering at moderately large momentum transfer factorises into parton-photon subprocess amplitudes and new form factors representing 1/x-moments of skewed parton distributions. A detailed phenomenological study for polarised and unpolarised real and virtual Compton scattering is presented
