Generalized Parton Distributions of Light Nuclei

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.

Light-Front Dynamics and Generalized Parton Distributions

High energy reactions necessarily involve large momentum transfer to the target’s constituents, which thus rebound near light speed. The experimentally observed correlation between initial and final states measures the system’s response along the light cone. A convenient theoretical description of such reactions is light-front dynamics where the properties of physical states are described along...

Parton Distributions in Nuclei

We discuss two topics in this talk. One is a brief overview of nuclear parton distributions, and the other is SU(2)-flavor-symmetry breaking in nuclear antiquark distributions. First, we show that nuclear structure functions F 2 (x) could be explained in a Q rescaling model with parton recombination effects. Then, nuclear gluon distributions are discussed in this parton model. We point out othe...

Generalized Parton Distributions and Transversity in Nucleons and Nuclei

Generalized parton distributions and strong forces inside nucleons and nuclei

We argue that generalized parton distributions (GPDs), accessible in hard exclusive processes, carry information about the spatial distribution of forces experienced by quarks and gluons inside hadrons. This way the measurements of hard exclusive processes open a possibility for direct “measurements” of strong forces in different parts of nucleons and nuclei. Also such studies open a venue for ...
