The role of the chiral phase transition in modelling the kaon to pion ratio

A sharp peak in the \(K^+/\pi^+\) ratio in relativistic heavy-ion collision is discussed in the framework of the SU(3) Polyakov-loop extended NJL model with vector interaction. In the model, the \(K^+/\pi^+\) ratio was calculated along the chiral phase transition line for different values of the vec...

Description
Summary:A sharp peak in the \(K^+/\pi^+\) ratio in relativistic heavy-ion collision is discussed in the framework of the SU(3) Polyakov-loop extended NJL model with vector interaction. In the model, the \(K^+/\pi^+\) ratio was calculated along the chiral phase transition line for different values of the vector coupling \(g_V\). We showed that the value of the vector coupling had no significant effect on the \(K^+/\pi^+\) behaviour.
