# Differential and total cross sections of high energy proton-proton scattering in holographic QCD

## TL;DR

This paper models high energy proton-proton scattering using holographic QCD, successfully matching experimental data at TeV energies by combining Reggeized propagators and gravitational form factors.

## Contribution

It introduces a holographic QCD framework for calculating proton-proton scattering cross sections incorporating Pomeron exchange and gravitational form factors.

## Key findings

- Results agree with LHC data at 13 TeV.
- The framework effectively describes nonperturbative dynamics.
- Demonstrates the validity of holographic QCD in high energy scattering.

## Abstract

The analysis on the high energy proton-proton scattering is presented, focusing on the Regge regime and considering the Pomeron exchange to describe the involved nonperturbative dynamics in the framework of holographic QCD. We combine the Reggeized spin-2 particle propagator and the proton gravitational form factor, which is obtained from the bottom-up AdS/QCD model, and calculate the differential and total cross sections. We explicitly demonstrate the comparison between our calculations and the currently available experimental data including the recent ones measured at $\sqrt{s} = 13$ TeV by the TOTEM collaboration at the LHC. It is shown that our results are consistent with the data, which implies that the present framework works in the considered TeV scale.
