Description
Heavy-ion collisions at energies of a few GeV involve significant baryon stopping in the fireball region, leading to the formation of a baryon-dominated system. This system is characterized by large values of the baryo-chemical potential ($\mu_B$) at chemical freeze-out, as determined through statistical-chemical analysis of hadron yields. However, at these lower energies, the freeze-out parameters are less constrained compared to higher-energy collisions, due to the rare production of certain hadron states. This imposes stringent requirements on experiments to gather sufficient data.
Furthermore, at lower collision energies, additional parameters beyond temperature ($T$), fireball volume ($V$), and baryo-chemical potential ($\mu_B$) as well as the treatment of light nuclei become increasingly important.
In this study, we employ updated methods that account for higher-order efficiency corrections from HADES experiments at GSI. This approach allows for a systematic and unprecedented precision analysis of baryon stopping and the global properties of matter at freeze-out, based on Au+Au and Ag+Ag collisions at $\sqrt{s_{NN}}$ = 2.42 and 2.55
GeV, respectively.
