论文摘要
我们研究了中心性定义和检测器效率对净蛋白峰度的影响，以$ \ sqrt {s _ {\ mathrm {nn}}} = 7.7 $ GEV的束能量，以$ \ sqrt {s _ {s _ {s _ {s _ {s _ {s _ {s _ {s _ sqrt {我们发现定义中心性的不同方法导致不同的累积比率。此外，我们证明，当使用更广泛的横向动量接受时，将抑制峰度用于中央碰撞。最后，估计检测器效率对测得的累积比率的影响。
We study the influence of the centrality definition and detector efficiency on the net-proton kurtosis for minimum bias Au+Au collisions at a beam energy of $\sqrt{s_{\mathrm{NN}}}= 7.7$ GeV by using the UrQMD model. We find that different ways of defining the centrality lead to different cumulant ratios. Moreover, we demonstrate that the kurtosis is suppressed for central collisions when a wider transverse momentum acceptance is used. Finally, the influence of a detector efficiency on the measured cumulant ratios is estimated.
