Description
QCD-inspired non-perturbative models provide an effective approach
to study strongly interacting matter at high temperature and/or
high density. The simultaneous onset of confinement and chiral
symmetry-breaking phenomena in lattice QCD (LQCD) simulations
inspired their coupling in effective models.
The Polyakov-Nambu-Jona-Lasinio or the PNJL model is one such QCD-inspired
non-perturbative model. The physics reflected from the behavior of thermodynamic
observables extracted from this model, gives an insight into QCD.
LQCD results have been recently obtained in the continuum limit
which consequently lowers the transition temperature. This motivates us
to modify the effective potential in the PNJL model.
Analysis of important thermodynamic observables with this potential
encouragingly show a similarity on
comparison to LQCD continuum data. We use this modified potential
to sketch the phase diagram.
