A Model Study on the Effects of n-Mesons on Thermodynamics of Strongly Interacting Systems

Abstract

Properties of strongly interacting matter are quite well-described by the Polyakov loop enhanced Nambu-Jona—Lasinio (PNJL) model as it incorporates two important symmetries. However, discrepancies in low temperature domain remain unless hadronic effects are entwined. Here we have tried to observe the effect of lowest lying hadrons i.e. ?-mesons (pions) considering their medium-dependent masses for zero chemical potential. The thermodynamic quantities now show satisfactory matches with existing lattice QCD and HRG results over the finite temperature window of interest.
