Radiative Corrections to Deeply Virtual Compton Scattering * )
Received XXX We discuss possibilities of measurement of deeply virtual Compton scattering amplitudes via different asymmetries in order to access the underlying skewed parton distributions. Perturbative one-loop coefficient functions and two-loop evolution kernels, calculated recently by a tentative use of residual conformal symmetry of QCD, are used for a model dependent numerical estimation o...
متن کاملFull O ( α ) Radiative Corrections to High - Energy Compton Scattering †
Using computer-algebraic methods we derive compact analytical expressions for the virtual electroweak radiative corrections to polarized Compton scattering. Moreover the helicity amplitudes for double Compton scattering, which prove to be extremely simple in terms of Weyl-van der Waerden spinor products, are presented for massless electrons. The inclusion of a finite electron mass is described,...
متن کاملNLO Corrections to Deeply - Virtual Compton Scattering ∗
We have calculated the NLO corrections to the twist-2 part of the deeply-virtual Compton scattering amplitude. Our results for the transverse and antisymmetric parts agree with recent calculations by Ji and Osborne and by Belitsky and Müller. In addition we present NLO results for the longitudinal part of the amplitude.
متن کاملRadiative corrections to deep – inelastic ed − scattering
The model–independent radiative corrections to deep–inelastic scattering of unpolarized electron beam off the tensor polarized deuteron target have been considered. The contribution to the radiative corrections due to the hard–photon emission from the elastic electron–deuteron scattering (the so–called elastic radiative tail) is also investigated. The calculation is based on the covariant param...
متن کاملRadiative Corrections to Polarized Inelastic Scattering in Coincidence
The complete analysis of the model–independent leading radiative corrections to cross– section and polarization observables in semi–inclusive deep–inelastic electron-nucleus scattering with detection of a proton and scattered electron in coincidence has been performed. The basis of the calculations consists of the Drell–Yan like representation in electrodynamics for both spin–independent and sp...
