Diffraction in hadron-hadron interactions

TL;DR

This paper reviews the behavior of diffraction in hadron-hadron collisions, highlighting the breakdown of conventional factorization at high energies and proposing a universal scaling approach based on rapidity gap probabilities.

Contribution

It introduces a universal scaling framework for diffractive processes that accounts for the breakdown of traditional factorization at high energies.

Findings

Conventional factorization breaks down at high energies.

A universal scaling behavior emerges in diffractive cross sections.

Diffractive processes can be described using a normalized rapidity gap probability distribution.

Abstract

Results on soft and hard diffraction in $pp$ and $\bar pp$ collisions are reviewed with emphasis on factorization and scaling properties of differential cross sections. While conventional factorization breaks down at high energies, a scaling behavior emerges, which leads to a universal description of diffractive processes in terms of a (re)normalized rapidity gap probability distribution.
