Correlation between conserved charges in PNJL Model with multi-quark interactions

Understand

We present a study of correlations among conserved charges like baryon number, electric charge and strangeness in the framework of 2+1 flavor Polyakov loop extended Nambu-Jona-Lasinio model at vanishing chemical potentials, up to fourth order.

• Correlations up to second order have been measured in Lattice QCD which compares well with our estimates given the inherent difference in the pion masses in the two systems.
• Possible physical implications of these correlations and their importance in understanding the matter obtained in heavy-ion collisions are discussed.
• We also present comparison of the results with the commonly used unbound effective potential in the quark sector of this model.
