# GPDs at non-zero skewness in ADS/QCD model

## TL;DR

This paper extends the AdS/QCD model to calculate Generalized Parton Distributions at non-zero skewness, revealing sensitivity to complex parton correlations in hadrons.

## Contribution

It generalizes the calculation scheme for GPDs at zero skewness to the non-zero skewness case within the AdS/QCD framework.

## Key findings

- GPDs at non-zero skewness are sensitive to hadronic light front wave function details.
- The generalized scheme captures parton correlations not seen at zero skewness.
- Results provide new insights into the three-dimensional structure of hadrons.

## Abstract

We study Generalized Parton Distribution functions (GPDs) usually measured in hard exclusive processes and encoding information on the three dimensional partonic structure of hadrons and their spin decomposition, for non zero skewness within the AdS/QCD formalism. To this aim the canonical scheme to calculate GPDs at zero skewness has been properly generalized. Furthermore, we show that the latter quantities, in this non forward regime, are sensitive to non trivial details of the hadronic light front wave function, such as a kind of parton correlations usually not accessible in studies of form factors and GPDs at zero skewness.
