Baryon productions and collective flow of relativistic heavy-ion collisions in the AGS, SPS, RHIC and LHC energy regions($\sqrt{s_{NN}}\leq5$GeV to 5.5 TeV)

TL;DR

This paper systematically studies net baryon production and collective flow in relativistic heavy-ion collisions across a wide energy range from AGS to LHC, using the Non-Uniform Flow Model, and predicts features at LHC energies based on lower-energy data.

Contribution

It introduces detailed predictions of baryon production and flow at LHC energies using the NUFM, extending understanding across multiple collider energy regimes.

Findings

Baryon stopping decreases with increasing collision energy.

Collective flow features vary with collision centrality and energy.

Predicted net baryon distributions at LHC energies.

Abstract

The features of net baryon productions and collective flow in relativistic heavy-ion collisions at energies reached at the CERN Large Hadron Collider (LHC), BNL Relativistic Heavy Ion Collider (RHIC), CERN Super Proton Synchrotron (SPS) and BNL Alternating Gradient Synchrotron (AGS) with the model of Non-Uniform Flow Model(NUFM) are systematically studied in this paper. Especially we predict the feature of net baryon productions and collective flow at LHC $\sqrt{s_{NN}}$=5500 GeV basing on the detailed study of that at RHIC $\sqrt{s_{NN}}$=62.4 and 200GeV. The dependencies of the features of baryon stopping and collective flow on the collision energies and centralities are investigated.
