Support of generalized parton distributions in Bethe-Salpeter models of hadrons

The proper support of generalized parton distributions from relativistic constituent quark models with pointlike constituents is studied. The correct support is guaranteed when the vertex function does not depend on the relative momentum. We show that including quark interactions in models with pointlike constituent quarks might lead to a support problem.

Generalized parton distributions of hadrons with composite constituents

A method is described for calculating the Generalized Parton Distributions (GPDs) of spin 1/2 hadrons made of composite constituents, in an Impulse Approximation framework. GPDs are obtained from the convolution between the light cone non-diagonal momentum distribution of the hadron and the GPD of the constituent. DIS structure functions and electromagnetic form factors are consistently recover...

Generalized parton distributions of nuclei

We review recent theoretical results on generalized parton distributions (GPDs) of nuclei, emphasizing the following three roles of nuclear GPDs: (i) complementarity to free proton GPDs, (ii) the enhancement of traditional nuclear effects such as nuclear binding, EMC effect, nuclear shadowing, and (iii) an access to novel nuclear effects such as medium modifications of bound nucleons.

Generalized Parton Distributions

■ Abstract This review explains why generalized parton distributions and the related quantum phase-space distributions are useful in exploring the quark and gluon structure of the proton and neutron. It starts with the physics of form factors and parton distributions. Then quantum phase-space distributions and their offspring are discussed. The properties of generalized parton distributions are...

Demystifying generalized parton distributions

In this paper, I will explain in as simple and intuitive physical terms as possible what generalized parton distributions are, what new information about the structure of hadrons they convey and therefore what picture of the hadron will emerge. To develop this picture, I will use the example of deeply virtual Compton scattering (DVCS) and exclusive meson electroproduction processes. Based on th...
