Applicability of Perturbative QCD to Pion Virtual Compton Scattering
We study explicitly the applicability of perturbative QCD (pQCD) to the pion virtual Compton scattering. It is found that there are central-region singularities introduced by the QCD running coupling constant, in addition to the end-point singularities generally existed in other exclusive processes such as the pion form factor. We introduce a simple technique to evaluate the contributions from ...
متن کاملQcd Sum Rule and Perturbative Qcd Approaches to Pion Compton Scattering
We compare two approaches to the description of pion Compton scattering at moderate momentum transfer, one being based on local duality QCD sum rules for the invariant amplitudes of the process, which have been derived recently, and the other on the modified factorization formula with Sudakov effects included. We find that perturbative QCD predictions are dominant over those from QCD sum rules ...
متن کاملThe Transition to Perturbative QCD in Compton Scattering
We investigate the transition to perturbative QCD in Compton processes, by concentrating on the specific reactions πγ → πγ and pion photoproduction at moderate energy scales. New sum rules for each of the helicities involved in the scattering and the cross section are given, together with a detailed stability analysis. Our results are then compared with those derived from higher-power factoriza...
متن کاملRecalculation of Proton Compton Scattering in Perturbative QCD
At very high energy and wide angles, Compton scattering on the proton (γp → γp) is described by perturbative QCD. The perturbative QCD calculation has been performed several times previously, at leading twist and at leading order in αs, with mutually inconsistent results, even when the same light-cone distribution amplitudes have been employed. We have recalculated the helicity amplitudes for t...
متن کاملPerturbative and Non-Perturbative QCD Corrections to Wide-Angle Compton Scattering
We investigate corrections to the handbag approach for wide-angle Compton scattering off protons at moderately large momentum transfer: the photon-parton subprocess is calculated to next-to-leading order in αs and contributions from the generalized parton distribution E are taken into account. Photon and proton helicity flip amplitudes are non-zero due to these corrections which leads to a weal...
