Susceptibilities of conserved charges of hadronic matter

An effective description of hadronic matter in terms of “effective free particles” is presented. Repulsive interactions among the hadrons have been modelled by Excluded volume correction by considering the hadrons as liquid drops, whose volume is inversely proportional to the cube root of the mass of the species. The only adjustable parameter in the model is pion radius. We get better agreement to the lattice results as compared to the previous studies.
