Fluctuations of conserved charges with finite size PNJL model
Paramita Deb, Raghava Varma · Research Square · 2024
Abstract Baryon, charge and strangeness fluctuations have been investigated in finite size Polyakov loop enhanced Nambu–Jona-Lasinio model. Multiple reflection expansion method has been incorporated to include the surface and curvature energy alongwith the system volume. The results of different fluctuations are then compared with the available experimental data from the heavy ion collision. Results show both qualitative and quantitative similarities with the experimental data after using the subensemble acceptance method. Phase diagram for the infinite and finite size PNJL model has been studied to estimate the critical end point. PACS numbers: 12.38.AW, 12.38.Mh, 12.39.-x
