Chemical freeze-out conditions and fluctuations of conserved charges in heavy-ion collisions within a quantum van der Waals model
The chemical freeze-out parameters in central nucleus-nucleus collisions are extracted consistently from hadron-yield data within the quantum van der Waals (QvdW) hadron resonance gas model. The beam energy dependencies for skewness and kurtosis of net baryon, net electric, and net strangeness charges are predicted. The QvdW interactions in asymmetric matter, …
