Model investigation on the probability of QGP formation in relativistic heavy ion collisions

TL;DR

This paper investigates the likelihood of quark-gluon plasma formation in relativistic heavy ion collisions using a bond percolation model, revealing size and centrality dependencies.

Contribution

It introduces a bond percolation model to analyze QGP formation probability across different nuclear sizes and collision centralities.

Findings

Smaller nuclei have less than 100% probability of QGP formation even at high energies.

QGP formation probability varies with nuclear size and collision centrality.

Heavier nuclei like Au and Pb have higher QGP formation probabilities.

Abstract

The formation probability of quark-gluon plasma in relativistic heavy ion collisions for colliding nuclei of different sizes is investigated in the framework of a bond percolation model. The results show that nuclei with sizes smaller than that of Pb or Au produce QGP with probability less than unity even at very high collision energies. The dependence of the QGP-formation probability on different nuclear sizes and on various centralities of Au-Au collision are presented.
