Rapidity Distribution within Landau hydrodynamical model and EPOS event-generator at RHIC Energies

TL;DR

This study compares rapidity distributions from BRAHMS experimental data with EPOS simulations and the Landau hydrodynamical model at RHIC energies, finding good agreement among all sources.

Contribution

It demonstrates that the Landau hydrodynamical model effectively describes rapidity distributions in heavy-ion collisions at RHIC energies, validated against experimental and EPOS simulation data.

Findings

Landau model matches BRAHMS data at 62.4 and 200 GeV

EPOS simulations agree with experimental results

Good overall agreement among models and experimental data

Abstract

The rapidity distribution of well-defined particles pions, Kaons, protons and their antiparticles measured in the BRAHMS experiment (Au+Au collisions), at $\sqrt{s_{NN}}$ = $62.4$ and $200$ GeV, are compared with huge statistical ensembles of 100, 000 events deduced from the Cosmic Ray MonteCarlo (CRMC) EPOS event-generator. All these data are then compared to the Landau hydrodynamical model. We conclude that the Landau hydrodynamical model is capable of describing both experimental data and EPOS $1.99$ event-generator results, and that they are in good agreement.
