NeXSPheRIO results on azimuthal anisotropy in Au-Au collisions at 200A GeV

TL;DR

This paper uses the NeXSPheRIO hydrodynamic model with fluctuating initial conditions to analyze azimuthal anisotropy in Au-Au collisions at 200A GeV, comparing results with RHIC data.

Contribution

It introduces event-by-event fluctuating initial conditions and explicit chemical freeze-out in hydrodynamic simulations for anisotropic flow analysis.

Findings

NeXSPheRIO results agree with experimental data on flow coefficients.

Directed, elliptic, and fourth harmonic flows are studied across centralities.

The model successfully reproduces key features of anisotropic flow at RHIC.

Abstract

In this work, we present the results obtained by the hydrodynamic code NeXSPheRIO on anisotropic flows. In our calculation, we made use of event-by-event fluctuating initial conditions, and chemical freeze-out was explicitly implemented. We studied directed flow, elliptic flow and forth harmonic coefficient for various hadrons at different centrality windows for Au+Au collisions at 200 AGeV. The results are discussed and compared with experimental data from RHIC.
