Abstract
We propose a modified liquid drop potential model to explore the thermodynamics of quark–gluon plasma (QGP) abovethe critical temperature, both in the absence and presence of amagnetic field. The model follows Mayer’s cluster expansion procedure.In this model, quarks and gluons are described as particles whose behavior is influenced by the QGP medium. Remarkably, evenat temperatures below the critical temperature (T < Tc), the equation of state for pressure and energy density across 2, 2+1 and 3flavors demonstrates a strong agreement with lattice data at zero magnetic field. Also, this modified liquid drop model is in goodagreement with lattice data for magnetized quark–gluon plasma in the region T > 113 MeV.
