Correlation Between Conserved Charges in Polyakov–Nambu–Jona-Lasinio Model with Multiquark Interactions Bhattacharyya, Abhijit; Deb, Paramita; Lahir, Anirban; Ray, Rajarshi We present a study of correlations among conserved charges like baryon number, electric charge and strangeness in the framework of 2 þ 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 a comparison of the results with the commonly used unbound effective potential in the quark sector of this model. DOI: 10.1103/PhysRevD.83.014011

Susceptibilities with Multi-quark Interactions in PNJL Model Bhattacharyya, Abhijit; Deb, Paramita; Lahir, Anirban; Ray, Rajarshi We have investigated the fluctuations and the higher order susceptibilities of quark number, isospin number, electric charge and strangeness at vanishing chemical potential for 2+1 flavor Polyakov loop extended Nambu–Jona-Lasinio model. The calculations are performed for the bound effective po- tential in the quark sector requiring up to eight quark interaction terms. These have been contrasted to the lattice results which currently have somewhat heavier quarks in the light flavor sector. The results show sufficient qualitative agreement. For comparison we also present the results obtained with the conventional effective potential containing upto six quark interaction terms. DOI: 10.1103/PhysRevD.82.114028
