Anisotropic hydrodynamic modeling of heavy-ion collisions at LHC and RHIC

TL;DR

This paper reviews the 3+1d quasiparticle anisotropic hydrodynamics model and demonstrates its effectiveness in describing experimental results from heavy-ion collisions at LHC and RHIC, including spectra, flow, and radii.

Contribution

It introduces and validates the aHydroQP model as a robust tool for modeling heavy-ion collision dynamics at high energies.

Findings

aHydroQP accurately describes spectra and multiplicity

Model reproduces elliptic flow and HBT radii well

Good agreement across multiple centrality classes

Abstract

In this proceedings contribution, we review 3+1d quasiparticle anisotropic hydrodynamics (aHydroQP). Then, we show some recent phenomenological comparisons between the aHydroQP model and some experimental results. We show comparisons between aHydroQP and Pb-Pb 2.76 TeV collisions from the ALICE collaboration and Au-Au 200 GeV collisions from RHIC experiments. We show that the quasiparticle anisotropic hydrodynamics model is able to describe the experimental results for Pb-Pb and Au-Au collisions quite well for many observables such as the spectra, multiplicity, elliptic flow, and HBT radii in many centrality classes.
