Skewed Parton Distributions and Real and Virtual Compton Scattering
نویسنده
چکیده
The soft physics approach to Compton scattering at moderately large momentum transfer is reviewed. It will be argued that in that approach the Compton cross section as well as other exclusive observables exhibit approximate scaling in a limited range of momentum transfer. Invited talk held at the workshop on exclusive and semi-exclusive processes at high momentum transfer, Jefferson Lab, May (1999).

Skewed Parton Distributions in Real and Virtual Compton Scattering
The handbag contribution to Compton scattering factorises in parton-photon subpro-cess 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. 1. The interest in the interplay between hard inclusive and exclusive reactions has recently been revived b...
متن کاملSKEWED PARTON DISTRIBUTIONS AND WIDE - ANGLE EXCLUSIVE SCATTERING P . Kroll
The overlap representation of skewed parton distributions (SPDs) is discussed and applications to wide-angle Compton scattering and electroproduction of mesons are presented. The amplitudes for these processes factorise into parton-level subprocess amplitudes and form factors representing 1/x-moments of SPDs. Key-words: skewed parton distributions, wide-angle exclusive reactions Invited talk pr...

The study of exclusive final states in electron-proton diffractive interactions is a very powerful tool to investigate the applicability and the relevance of perturbative Quantum Chromo Dynamics (QCD) in this field. At HERA, the wide kinematic range in the photon virtuality, Q, provides particular insight into the interplay between perturbative and non-perturbative regimes in QCD. Moreover, a c...
متن کاملSkewed Parton Distributions ∗
Applications of perturbative QCD to deeply virtual Compton scattering and hard exclusive electroproduction processes require a generalization of usual parton distributions for the case when long-distance information is accumulated in nonforward matrix elements of quark and gluon light-cone operators. We describe two types of nonperturbative functions parametrizing such matrix elements: double d...

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...
