Different variants of the Hadron Resonance Gas model have been used to describe the hadronic phase of strongly interacting matter. HRG model is improved by including repulsive interaction through the inclusion of excluded volume in Excluded…

We investigate the effect of repulsive interaction between hadrons on the susceptibilities of conserved charges, namely baryon number (B), electric charge (Q) and strangeness (S). We estimate second fourth and sixth-order susceptibilities…
