Description
Summary:This study investigates the phase transitions in QCD using Mayer’s cluster expansion method. The inter quark potential is modified Cornell potential. The equation of state (EoS) is evaluated for a homogeneous system. The behaviour is studied by varying the temperature as well as the number of Charm Quarks. The results clearly show signs of phase transition from Hadrons to Quark-Gluon Plasma (QGP). •Condensation of QGP is presented.•EoS using modified Cornell potential is investigated.•Ushcats convergence method for cluster expansion is used.•Isotherm for different temperature and different number of charm quarks is obtained.•A comparison of Mayer’s relation with that of Ushcats is made.
