On Matter and Pressure Distribution in Nucleons

Abstract

Matter and pressure distribution in hadrons are studied in a dual analytic model of generalized parton distributions with complex Regge trajectories. An original parametrization of the pressure distribution in the nucleon is proposed, ensuring its stability and compatible with the experimental data from the JLab accelerator.
