Description
The investigation of Generalized Parton Distributions (GPDs) provides a unique perspective on understanding the nucleon’s structure. Unlike traditional methods that rely on probes like photons and pions to explore nucleon form factors, this approach faces limitations when dealing with tensor and gravitational form factors. GPDs offer a solution by allowing the redefinition of these form factors as moments of the GPDs, particularly for the energy-momentum tensor form factors or gravitational form factors (GFFs), which emerge as the second moments of vector GPDs. This redefinition enables the circumvention of probe-related issues. The GFFs, representing the second moments, provide valuable insights into the mechanical structure of the nucleon. In this presentation, we will discuss recent studies focusing on nucleon GFFs and their associated densities. A key emphasis will be placed on the D-term form factor, which holds equal significance to electromagnetic form factors. The findings presented in this talk are intricately linked to the physics program of the Electron-Ion Collider (EIC).
