Universal hadronization condition in heavy ion collisions at $\sqrt{s_\mathrm{NN}}= 62$ GeV and at $\sqrt{s_\mathrm{NN}}=2.76$ TeV

TL;DR

This paper demonstrates that the hadronization process in heavy ion collisions at different energies occurs under nearly identical physical conditions, indicating a universal hadronization condition across energies.

Contribution

It provides a detailed analysis showing that the hadronization conditions at LHC are similar to those at RHIC, suggesting a universal hadronization criterion in heavy ion collisions.

Findings

Hadronization occurs at similar conditions across different energies.

Universal hadronization condition observed at LHC and RHIC.

Consistent hadron yields across centralities at LHC.

Abstract

We obtain a detailed description of all available hadron multiplicity yields in central Pb--Pb collisions at LHC measured in the rapidity interval $|y|<0.5$. We find that the hadronization of the fireball at LHC occurs at nearly identical intensive physical bulk conditions for all centralities similar to those seen already at RHIC.
