Deep Virtual Compton Scattering and the Nucleon Generalized Parton Distributions
In the following, the subject of Deep Virtual Compton Scattering on the nucleon and its relation to the recently introduced concept of Generalized Parton Distributions are briefly reviewed. The general theoretical framework and the links between theory and experiment will be outlined and the recently published data which look promising for the development of this field will be discussed. Finall...
متن کاملGeneralized Parton Distributions, Deeply Virtual Compton Scattering and TMDs
Parton distributions in impact parameter space, which are obtained by Fourier transforming GPDs, exhibit a significant deviation from axial symmetry when target and/or quark are transversely polarized. In combination with the final state interactions, this transverse deformation provides a natural mechanism for naive-T odd transverse single-spin asymmetries in semi-inclusive DIS. The deformatio...

We present a comparison of a recently proposed model, which describes the Deeply Virtual Compton Scattering amplitude, to the HERA data.
متن کاملSkewed 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 Real and Virtual Compton Scattering
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 (1...
