Jet modification in absence of QGP-medium: the role of multiparton interactions and color reconnection
Prottoy Das, Abhi Modak, Debjani Banerjee +5
Recent studies of high-multiplicity events in small collision systems (proton-proton and proton-lead) have drawn research interest towards the possibility of the formation of parto…
Thermodynamics of strongly interacting matter in a hybrid model
Abhijit Bhattacharyya, Sanjay K. Ghosh, Soumitra Maity +5
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…
Reparametrizing the PolyakovNambuJona-Lasinio model
Abhijit Bhattacharyya, Sanjay K. Ghosh, Soumitra Maity +4
The PolyakovNambuJona-Lasinio model has been quite successful in describing various qualitative features of observables for strongly interacting matter, that are measurable i…
Polyakov--Nambu--Jona-Lasinio model in finite volumes
Abhijit Bhattacharyya, Sanjay K. Ghosh, Rajarshi Ray +2
We discuss the 2+1 flavor Polyakov loop enhanced Nambu--Jona-Lasinio model in a finite volume. The main objective is to check the volume scaling of thermodynamic observables for va…
Exploring effects of magnetic field on the Hadron Resonance Gas

Quark Number Susceptibility : Revisited with Fluctuation-Dissipation Theorem in mean field theories
Sanjay K. Ghosh, Anirban Lahiri, Sarbani Majumder +3
Fluctuations of conserved quantum numbers are associated with the corresponding susceptibilities because of the symmetry of the system. The underlying fact is that these fluctuatio…
Fluctuations and correlations of conserved charges in an excluded volume hadron resonance gas model
Abhijit Bhattacharyya, Supriya Das, Sanjay K. Ghosh +2
We present temperature () and baryonic chemical potential () dependence of higher order fluctuations and correlation between conserved charges in Excluded Volume Hadron Res…
Net Charge Fluctuations as a signal of QGP from Polyakov-Nambu-Jona-Lasinio model
Abhijit Bhattacharyya, Supriya Das, Sanjay K. Ghosh +4
We report the first model study of the net charge fluctuations in terms of D-measure within the framework of the Polyakov-Nambu-Jona-Lasinio model. Net charge fluctuation is estima…
Isospin symmetry breaking and baryon-isospin correlations from PolyakovNambuJona-Lasinio model
