Elliptic flow: pseudorapidity and number of participants dependence

TL;DR

This paper investigates how elliptic flow varies with pseudorapidity and participant number using string percolation, emphasizing the role of initial geometry in azimuthal asymmetries, and shows good agreement with experimental data.

Contribution

It introduces a geometric model based on string percolation to explain elliptic flow dependence on pseudorapidity and participant number.

Findings

Good agreement with experimental data

Elliptic flow depends on initial geometry

Initial overlap region influences azimuthal asymmetries

Abstract

We discuss the elliptic flow dependence on pseudorapidity and number of participating nucleons in the framework of string percolation, and argue that the geometry of the initial overlap region of interaction, projected in the impact parameter plane, determines the experimentally measured azimuthal asymmetries. We found good agreement with data.
