Correlating the skewness and kurtosis of baryon number distributions

Understand

The skewness and the kurtosis of the baryon number distributions are computed within QCD-improved low energy effective models including quantum thermal and density fluctuations.

• The results are compared with the Beam Energy Scan experiment at RHIC.
• The theoretical results agree with the experimental measurements up to errors, for the collision energy $\sqrt{s}\ge 19.6\,\mathrm{GeV}$.
• For smaller collision energies a discrepancy between theoretical and experimental results develops.
