Universality of Hadronization Condition at RHIC and LHC

The hadronization analysis within non-equilibrium SHM has shown that across RHIC and LHC energy range, and across a wide range of centrality we find a universal intensive hadronization conditions of the particle source: pressure $P_h\simeq 80$MeV/fm$^3$, energy density $\varepsilon_h\simeq 0.5$GeV/fm$^3$ and entropy density $\sigma_h\simeq 3.3$fm$^{-3}$. The parameters varying as a function of reaction energy and/or centrality are source volume $dV/dy$ and strangeness saturation $\gamma_s$. This discovery allows to simplify the SHM approach: the principle of Universal Hadronization reduces the number of parameters within the non-equilibrium SHM. Two suffice at LHC and three are enough at RHIC to fully characterize all hadron production. We show this using the SHARE program: we prescribe the intensive properties of the fireball, and fit at LHC $dV/dy$, $\gamma_s$ as a function of centrality, while at RHIC we must also introduce baryon--antibaryon asymmetry $\mu_B$, where $\mu_S$ is fixed by $< s >=< \bar s >$. The other SHM parameters e.g. $T,\ \gamma_q$, are an output of this procedure, which works for all hadrons. The convergence for the most central collisions of $s/S\to 0.03$ confirms strangeness chemical equilibration in the deconfined QGP fireball hadron source.
