I developed a dynamical model devoted to studying the cooling of a quark-antiquark plasma and its hadronization into mesons and baryons. To perform this modeling, I considered the Nambu–Jona-Lasinio (NJL) model, completed by the inclusion of a Polyakov loop, to form the PNJL model. I studied the mesonization, but also the baryonization of this system, thanks to cross sections calculated according to $\sqrt{s},$ the temperature, and the densities. In the performed simulations, I identified the dominant reactions. I also underlined the existence of a remote interaction between quarks. A purpose of this paper was to compare the NJL and PNJL results to see if one of these two models can make it possible to obtain a full hadronization of an open system initially composed of quarks and antiquarks.
