Critical point of nuclear matter and beam-energy dependence of net-proton number fluctuations
The beam energy dependence of net baryon number susceptibilities is studied in the framework of the hadron resonance gas model with the attractive and repulsive van der Waals interactions between baryons. The collision energy dependences for the skewness $S\ensuremath{\sigma}$ and kurtosis $\ensuremath{\kappa}{\ensuremath{\sigma}}^{2}$ deviate significantly from the Poisson baseline and demonstrate …
