GPDs of the Nucleons and Elastic Scattering at LHC Energies

TL;DR

This paper develops a new model incorporating electromagnetic and gravitational form factors derived from t-dependent GPDs, successfully describing existing data and predicting elastic scattering behaviors at LHC energies.

Contribution

It introduces a novel model combining soft and hard pomerons with form factors from t-dependent GPDs, fitting experimental data with only four free parameters.

Findings

Qualitative agreement with experimental data up to 52.8 GeV

Model provides predictions for LHC energies

Achieves description including Coulomb range and large momentum transfers

Abstract

Taking into account the electromagnetic and gravitational form factors, calculated from a new set of $t $-dependent GPDs, a new model including the soft and hard pomerons is build. In the framework of this model the ualitative description of all existing experimental data at $\sqrt{s} \leq 52.8 $ GeV, including the Coulomb range and large momentum transfers, is obtained with only 4 free parameters. Predictions for LHC energies are made.
