Contribution

It proposes a novel t-dependence framework for GPDs, enabling detailed analysis of nucleon gravitational form factors and quark contributions.

Findings

Successful reproduction of proton and neutron electromagnetic form factors

Derivation of nucleon gravitational form factors

Quantification of quark contributions to gravitational form factors

Abstract

In the framework of the new t-dependence of the General Parton Distributions (GPDs), which reproduce the electromagnetic form factors of the proton and neutron at small and large momentum transfer, the gravitational form factors of the nucleons and a separate contribution of the quarks to them are obtained.
