Transverse Radial Flow Effects on Two- and Three-Particle Angular Correlations

TL;DR

This paper demonstrates how modest transverse radial flow in heavy-ion collisions can significantly alter two- and three-particle angular correlations, potentially mimicking phenomena like the ridge and conical emission.

Contribution

It introduces a simple model coupling radial flow with PYTHIA events to analyze its effects on particle correlations in heavy-ion collisions.

Findings

Radial flow can produce strong modifications in correlation functions.

Flow effects may mimic the ridge and conical emission structures.

Modest radial velocities are sufficient to cause significant changes.

Abstract

We use a simple a transverse radial boost scenario coupled to PYTHIA events to illustrate the impact radial flow may have on two- and three-particle correlation functions measured in heavy-ion collisions. We show that modest radial velocities can impart strong modifications to the correlation functions, some of which may be interpreted as same side ridge and away side structure that can mimic conical emission.
