Deep Exclusive Scattering and Generalized Parton Distributions: Experimental Review
نویسنده
چکیده
Since the Generalized Parton Distribution theoretical framework was introduced in the late 90’s, a few published and numerous preliminary results from Deep Exclusive Scattering (DES) have been extracted from non-dedicated experiments at HERA and Jefferson Lab. We review most of these results, comment on the ongoing dedicated research in this topic and conclude with the expectations from the next generation of experiments in the near future.

Generalized parton distributions: Status and perspectives
We summarize recent developments in understanding the concept of generalized parton distributions (GPDs), its relation to nucleon structure, and its application to high–Q2 electroproduction processes. Following a brief review of QCD factorization and transverse nucleon structure, we discuss (a) new theoretical methods for the analysis of deeply–virtual Compton scattering (t–channel–based GPD pa...
متن کاملGeneralized parton distributions in the deuteron.
We introduce generalized quark and gluon distributions in the deuteron, which can be measured in exclusive processes like deeply virtual Compton scattering and meson electroproduction. We discuss the basic properties of these distributions and point out how they probe the interplay of nucleon and parton degrees of freedom in the deuteron wave function.

متن کاملDeeply Virtual Compton Scattering with Positron Beams at Jefferson Lab
The challenge of understanding nucleon electromagnetic structure still continues after more than five decades of experimental scrutiny. From the initial measurements of elastic form factors to the accurate determination of parton distributions through deep inelastic scattering, the experiments have increased in statistical and systematic accuracy. Only during the past decade it was realized tha...
