Fluctuations in the Statistical Model of the Early Stage of nucleus-nucleus collisions

TL;DR

This paper predicts how fluctuations in hadron production during early-stage nucleus-nucleus collisions can signal the onset of deconfinement, using an extended statistical model that considers strongly intensive measures.

Contribution

It introduces an extension to the Statistical Model of the Early Stage by incorporating strongly intensive fluctuation measures, predicting significant energy dependence changes due to phase transition.

Findings

Predicted significant changes in fluctuation measures at certain collision energies.

Identified potential signals for the onset of deconfinement.

Extended the statistical model to include fluctuation analysis.

Abstract

Predictions on fluctuations of hadron production properties in central heavy ion collisions are presented. They are based on the Statistical Model of the Early Stage and extend previously published results by considering the strongly intensive measures of fluctuations. In several of the considered cases a significant change in collision energy dependence of calculated quantities as a result of the phase transition is predicted. This provides an opportunity to observe new signals of the onset of deconfinement in heavy ion collisions experiments.
