Qcd Sum Rules and Compton Scattering
We extend QCD sum rule analysis to moderate energy fixed angle Compton scattering. In this kinematic region there is a strong similarity to the sum rule treatment of electromagnetic form factors, although the four-point amplitude requires a modification of the Borel transform. To illustrate our method, we derive the sum rules for helicity amplitudes in pion Compton scattering and estimate their...
متن کاملNext-to-leading order mass effects in QCD Compton process of polarized DIS
A lot of articles dedicated to NLO QCD corrections to polarized DIS have been published. Calculations in most of them are performed in an assumption that the quark mass is equal to zero (see [1, 2, 3, 4, 5, 6, 7] and review [8]). However there are some works when authors estimate a finite quark mass effect for both unpolarized [9] and polarized structure functions [10, 11, 12, 13, 14, 15, 16]. ...
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 کاملApplicability 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 ...
