# Regge models of proton diffractive dissociation based on factorization and structure functions

## TL;DR

This paper reviews and updates models of proton diffractive dissociation at the LHC, introducing a Pomeron structure function to describe inelastic Pomeron-Pomeron interactions, building on previous proton structure function approaches.

## Contribution

It introduces a novel approach using a Pomeron structure function to model inelastic Pomeron-Pomeron vertices in diffraction processes.

## Key findings

- Effective description of inelastic Pomeron-Pomeron interactions
- Enhanced modeling of low-mass resonance region
- Application to LHC diffractive dissociation data

## Abstract

Recent results by the authors on proton diffractive dissociation (single, double and central) in the low-mass resonance region with emphasis on the LHC kinematics are reviewed and updated. Based on the previous ideas that the contribution of the inelastic proton-Pomeron vertex can be described by the proton structure function, the contribution of the inelastic Pomeron-Pomeron vertex appearing in central diffraction is now described by a Pomeron structure function.
