| Abstract: | This article investigates the thermodynamic properties of the SU(2) Nambu–Jona–Lasinio (NJL) model under the chiral chemical potential μ 5 , employing Tsallis non-extensive statistics. The introduction of the parameter q , which characterizes the non-extensivity of the system through Tsallis statistics, offers a novel perspective for studying the behavior of strongly interacting matter under extreme conditions. By calculating thermodynamic quantities such as quark mass, critical temperature, chiral density, pressure, entropy, and speed of sound, we systematically analyze the effects of μ 5 and q on these quantities. It is observed that both μ 5 and q exhibit an inverse relationship with the critical temperature T pc , while showing a positive correlation with the chiral density n 5 . [ABSTRACT FROM AUTHOR] |
