摘要：

In this work we discuss a modified version of Excluded Volume Hadron Resonance Gas model and also study the effect of Lorentz contraction of the excluded volume on scaled pressure and susceptibilities of conserved charges. We find that the Lorentz contraction, coupled with the variety of excluded volume parameters reproduces the lattice QCD data quite satisfactorily. (c) 2021 Elsevier B.V. All rights reserved.
