Longitudinal hydrodynamic expansion and long rangle correlations

TL;DR

This paper demonstrates how long-range correlation analysis can verify the hydrodynamic nature of longitudinal expansion in high-energy collisions, with specific application to the ALICE detector.

Contribution

It introduces a method to test the hydrodynamic behavior of the partonic system's expansion using long-range correlations in multiparticle production.

Findings

Method effectively verifies hydrodynamic expansion

Application to ALICE detector data

Supports hydrodynamic models of collision dynamics

Abstract

It is shown that the recently proposed method of studying the long-range correlations in multiparticle production can be effectively used to verify the hydrodynamic nature of the longitudinal expansion of the partonic system created in the collision. The case of ALICE detector is explicitly considered.
