National Technical Reports Library

The National Technical Information Service acquires, indexes, abstracts, and archives the largest collection of U.S. government-sponsored technical reports in existence. The NTRL offers online, free and open access to these authenticated government technical reports. Technical reports and documents in its repository may be available online for free either from the issuing federal agency, the U.S. Government Publishing Office’s Federal Digital System website, or through search engines.

Deeply Virtual Compton Scattering with CLAS.

DE2007921029

Publication Date	2007
Personal Author	Girod, F. X.
Page Count	4
Abstract	The introduction of parton Wigner distributions in the nucleon provided us with a rigorous landscape of the different approaches to the hadron structure, linking together all possible hadronic observables. There is unfortunately as of today no known experimental process to access them. Projecting out light-cone energy and transverse momenta, a Fourier transform leads to Generalized Parton Distributions (GPDs). Those encompass Form Factors and Parton Distribution Functions, as well as a wealth of new physical informations. For instance, the Energy-Momentum tensor of partons in the nucleon can be parameterized in terms of GPDs, providing distributions of masses, angular momenta, or forces inside the nucleon.
