Further studies of multiplicity derivative in models of heavy ion collision at intermediate energies as a probe for phase transition

TL;DR

This paper investigates how the multiplicity derivative in heavy ion collision models can serve as an indicator of phase transition, comparing model predictions with experimental data to identify signatures of first-order phase transitions.

Contribution

It introduces the use of multiplicity derivative as a probe for phase transition in heavy ion collisions and compares results across different models.

Findings

Two models suggest signatures of phase transition

One model's results differ significantly

Multiplicity derivative can indicate first-order phase transition

Abstract

In conjunction with models, the experimental observable total multiplicity can be used to check if the data contain the signature of phase transition and if it is first order. Two of the models reach similar conclusions. The third one is quite different.
