# Coulomb final state interaction in heavy ion collisions for Levy sources

## TL;DR

This paper explores how Coulomb final state interactions affect particle correlations in heavy ion collisions, especially for Levy-type sources, advancing the understanding of space-time dynamics in such high-energy reactions.

## Contribution

It introduces a detailed analysis of Coulomb interactions for Levy sources, extending beyond the simple Gamow factor used in smaller systems.

## Key findings

- Coulomb interactions significantly influence particle correlations in heavy ion collisions.
- Levy sources require more complex treatment of Coulomb effects than point-like models.
- The study provides a framework for more accurate modeling of space-time particle production.

## Abstract

Investigation of momentum space correlations of particles produced in high energy reactions requires taking final state interactions into account, a crucial point of any such analysis. Coulomb interaction between charged particles is the most important such effect. In small systems like those created in e+e- or p+p collisions, the so-called Gamow factor (valid for a point-like particle source) gives an acceptable description of the Coulomb interaction. However, in larger systems such as central or mid-central heavy ion collisions, more involved approaches are needed. In this paper we investigate the Coulomb final state interaction for Levy-type source functions that were recently shown to be of much interest for a refined description of the space-time picture of particle production in heavy-ion collisions.
