Probing the nucleon at large momentum tramsfer

TL;DR

This paper explores the role of soft nucleon matrix elements, described via skewed parton distributions, in high-energy electron and photon interactions with nucleons, highlighting their connections to various scattering processes.

Contribution

It provides an analysis of how skewed parton distributions relate to traditional parton distributions, form factors, and scattering phenomena, offering insights into nucleon structure at high energies.

Findings

Skewed parton distributions connect to form factors and ordinary parton distributions.

Soft matrix elements are central to understanding high-energy nucleon reactions.

The paper discusses the implications for Compton scattering and meson electroproduction.

Abstract

The central role of soft nucleon matrix elements in reactions of high energy electrons or real photons with nucleons is emphasized. These soft matrix elements are described in terms of skewed parton distributions. Their connections to ordinary parton distributions, form factors, Compton scattering and hard meson electroproduction is discussed.
