Generalized hadron structure and elastic scattering

TL;DR

This paper introduces a new parameterization of GPDs' t-dependence that effectively models electromagnetic form factors and elastic nucleon-nucleon scattering across various momentum transfers.

Contribution

It presents a novel form of GPDs' t-dependence that improves the description of proton and neutron form factors and high-energy elastic scattering.

Findings

Accurately reproduces proton and neutron electromagnetic form factors.

Provides a good description of high-energy elastic nucleon-nucleon scattering.

Shows the new GPD parameterization's effectiveness across different momentum transfers.

Abstract

The new parameterization of the Generalized Parton Distributions (GPDs) t-dependence is investigated. It is shown that the new form of the GPDS allows one to reproduce sufficiently well the electromagnetic form factors of the proton and neutron at small and large momentum transfer and obtain a good description of the elastic nucleon-nucleon scattering at high energies.
