Generalized parton distributions and strong forces inside nucleons and nuclei — •Maxim V. Polyakov — Petersburg Nuclear Physics Institute, Gatchina — Institute for Theor. Physics II, Ruhr Univrsity Bochum, 44780 Bochum

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 “measurementsNo-dq of strong forces in different parts of nucleons and nuclei. Also such studies open a venue for addressing questions of the properties of the quark (gluon) matter inside hadrons and nuclei. We give a simple example of relations between GPDs and properties of “nuclear matterNo-dq in finite nuclei.
