Contribution

It introduces a DSE-based method for calculating susceptibilities and validates it against experimental and lattice QCD data.

Findings

DSE results agree well with experimental fluctuation data.

DSE approach effectively models baryon-number susceptibilities.

Supports the use of DSEs in heavy ion collision studies.

Abstract

Since the baryon-number susceptibilities are correlated with the cumulant of baryon-number fluctuations in experiments, we do calculations of the susceptibilities and compare them with the experimental fluctuation data under the framework of the Dyson-Schwinger equations (DSEs) approach. We compare our results with lattice QCD and experimental data at RHIC. The fitness of the results indicates that under the framework of DSEs, we can deal with the problems of heavy ion collisions properly.
