Modified Excluded Volume Hadron Resonance Gas Model with Lorentz Contraction

Abstract

In this work we discuss a modified version of Excluded Volume Hadron Resonance Gas model (MEVHRG) and also study the effect of Lorentz contraction of the excluded volume on scaled pressure and susceptibilities of conserved charges. We take four different sets of hadronic radii and compare their results. We find that a larger variety of radii for hadrons enlarges the difference between the results of MEVHRG model and EVHRG model.
