重子数分布的偏度和峰度的计算在QCD改进的低能有效模型，包括量子热和密度涨落。并与RHIC的束流能量扫描实验进行了比较。理论计算结果与实验测量结果在误差范围内一致，碰撞能量为19.6GeV.对于较小的碰撞能量的理论和实验结果之间的差异发展。这种差异部分涉及到目前的小碰撞能量的设置缺乏精度。它概述了如何克服这一缺陷。
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. This discrepancy partially relates to the lack of precision of the current setup for small collision energies. It is outlined how this deficiency can be overcome.
