Comment on "Evaluation of kinetic freeze-out properties in different relativistic heavy-ion collision systems at \sqrtsNN = 200 GeV'' (Eur. Phys. J. Plus (2025) 140:179) https://doi.org/10.1140/epjp/s13360-025-06119-0

Abstract

The comment raises serious concerns regarding the authors claims about the phase transition from the QGP phase to the hadron gas phase. Additionally, the comment critiques the fundamental distinction between the kinetic freeze-out temperature and the critical temperature, as the authors erroneously treat them as identical in their article. The authors also assert that the critical temperature is system dependent which contradicts established lattice QCD calculations. Furthermore, there are flaws in their handling of data uncertainties, which could significantly affect the quality of the fit. Furthermore, they misrepresent AMPT-simulated data as experimental data, which undermines the validity of their analysis. Flaws in their handling of data uncertainties also cast doubt on the robustness of their fits.
