Abstract We discuss three applications of NJL- and PNJL-like models to assess aspects of the QCD phase diagram: First, we study the effect of mesonic correlations on the pressure below and above the finite temperature phase transition within a non-local PNJL model beyond the mean-field approximation. Second, we reconstruct the phase boundary of an NJL model from a Taylor expansion of the chiral susceptibility about μ = 0 and compare the result with the exact phase boundary. Finally, we… Expand

Isospin Effect on Baryon and Charge Fluctuations from the pNJL Model
We have studied the possible isospin corrections on the skewness and kurtosis of netbaryon and net-charge fluctuations in the isospin asymmetric matter formed in relativistic heavy-ion collisions atExpand
Thermodynamics of strongly interacting matter in a hybrid model
The equation of state and fluctuations of conserved charges in a strongly interacting medium under equilibrium conditions form the baseline upon which various possible scenarios in relativisticExpand


NJL model study of the QCD phase diagram using the Taylor series expansion technique
In a simple Nambu-Jona-Lasinio (NJL) model we investigate the QCD phase diagram, first by applying conventional mean field calculation, then using a Taylor series expansion of the grand thermodynamicExpand
The chiral and deconfinement crossover transitions: PNJL model beyond mean field ∗
Abstract The Polyakov loop extended Nambu and Jona-Lasinio model (PNJL model) in a mean field framework shows astonishingly good agreement with lattice QCD calculations which needs to be betterExpand
QCD thermodynamics at zero and non-zero density
Abstract We present results on the QCD equation of state, obtained with two different improved dynamical staggered fermion actions and almost physical quark masses. Lattice cut-off effects areExpand
Chiral effective model with the Polyakov loop
We discuss how the simultaneous crossovers of deconfinement and chiral restoration can be realized. We propose a dynamical mechanism assuming that the effective potential gives a finite value of theExpand
Phases of QCD: lattice thermodynamics and a field theoretical model
We investigate three-color QCD thermodynamics at finite quark chemical potential. Lattice QCD results are compared with a generalized Nambu Jona-Lasinio model in which quarks couple simultaneously toExpand
The pressure in 2, 2+1 and 3 flavour QCD
We calculate the pressure in QCD with two and three light quarks on a lattice of size 16 3 × 4 using tree level improved gauge and fermion actions. We argue that for temperatures T > 2Tc systematicExpand
Chiral symmetry restoration and Z N symmetry
Abstract We demonstrate that chiral symmetry restoration in quenched finite temperature QCD depends crucially on the Z 3 phase of the Polyakov loop P . This dependence is a general consequence of theExpand
