TL;DR
This paper computes nucleon generalized parton distributions at zero skewness using an AdS/QCD model, linking form factors to GPDs through a matching procedure, advancing the theoretical understanding of nucleon structure.
Contribution
It introduces a novel method to calculate GPDs in AdS/QCD by matching sum rules with electromagnetic form factors.
Findings
GPDs are successfully derived within the AdS/QCD framework.
The approach provides insights into the nucleon structure at zero skewness.
Results align with known experimental data and theoretical expectations.
Abstract
The nucleon helicity-independent generalized parton distributions (GPDs) of quarks are calculated in the zero skewness case, in the framework of the AdS/QCD model. The present approach is based on a matching procedure of sum rules relating the electromagnetic form factors to GPDs and AdS modes.
