# Total Hadronic Cross Sections via the Holographic Pomeron Exchange

## TL;DR

This paper uses holographic QCD to calculate high-energy hadron-hadron total cross sections via Pomeron exchange, successfully matching experimental data and extending predictions to other hadron interactions.

## Contribution

It introduces a holographic QCD framework combining Pomeron exchange and hadron couplings from bottom-up AdS/QCD models for calculating total cross sections.

## Key findings

- Calculated nucleon-nucleon cross sections match LHC data.
- Predicted pion-nucleon and pion-pion cross sections.
- Framework can be applied to various hadron scattering processes.

## Abstract

The analysis on the hadron-hadron scattering at high energies in the framework of holographic QCD is presented. Combining the Pomeron exchange kernel and the hadron-Pomeron couplings which are obtained from the bottom-up AdS/QCD models, we calculate the total cross sections. Our calculation for the nucleon-nucleon scattering is consistent with the experimental data including the recent ones measured by the TOTEM collaboration at the LHC. Within the framework, one can consider other processes involving other hadrons. As examples to show this feature of the model, the resulting total cross sections of the pion-nucleon and pion-pion scattering are also presented.
