## Abstract

We explore a hadron resonance gas model using Tsallis non-extensive distribution to study the energy dependence of the product of the moments, $S\\sigma$ and $\\kappa\\sigma^2$ of net-proton multiplicity distributions of published STAR data in \\auau collisions at relativistic heavy-ion collider (RHIC) energies. While excellent agreements are found between model predictions and measurements of $S\\sigma$ and $\\kappa \\sigma^2$ of most peripheral collisions and $S\\sigma$ of most central collisions, the $\\kappa \\sigma^2$ for most central collisions deviates significantly from the predictions particularly at \\sqsn = 19.6 GeV and $27$ GeV. This could be an indication of the presence of dynamical fluctuations, which are not contained in the HRG-Tsallis model.

## Recorded benchmark results

A research result applies to its stated dataset, split, metric and evaluation configuration. Compare like-for-like settings, preserve the metric's unit and direction, and distinguish paper-reported results from independent reproduction. The best result recorded here is not a claim of exhaustive, current global coverage.
