# Analysis of Deeply Virtual Compton Scattering Data at Jefferson Lab and Proton Tomography

## TL;DR

This paper analyzes recent Jefferson Lab data on Deeply Virtual Compton Scattering using GPD formalism, extracting constraints on Compton Form Factors and exploring the proton charge radius dependence on quark momentum.

## Contribution

It introduces a fitter algorithm to extract Compton Form Factors from new experimental data and investigates the proton charge radius variation with quark momentum.

## Key findings

- New constraints on three Compton Form Factors derived from data.
- Proton charge radius dependence on quark longitudinal momentum fraction established.
- Enhanced understanding of proton structure through GPD analysis.

## Abstract

The CLAS and Hall A collaborations at Jefferson Laboratory have recently released new results for the ep->ep{\gamma} reaction. We analyze these new data within the Generalized Parton Distribution formalism. Employing a fitter algorithm introduced and used in earlier works, we are able to extract from these data new constraints on the kinematical dependence of three Compton Form Factors. Based on experimental data, we subsequently extract the dependence of the proton charge radius on the quarks longitudinal momentum fraction.
