论文摘要
在重型离子碰撞的事件中，我们引入了一种快速而简单的计算净质子或净收税波动累积的方法。一个人在每个流体动力事件中评估颗粒的平均数量。然后将累积物表示为这些平均数的函数。由于全球保护法，我们实施了更正。该方法使用$ \ sqrt {s_ {nn}} = 200 $ agev的理想流体动力模拟使用nexspherio代码进行测试。结果与星际合作的网络蛋白和网络充电波动的实验数据非常吻合。
We introduce a fast and simple method of computing cumulants of net-proton or net-charge fluctuations in event-by-event hydrodynamic simulations of heavy-ion collisions. One evaluates the mean numbers of particles in every hydrodynamic event. Cumulants are then expressed as a function of these mean numbers. We implement the corrections due to global conservation laws. The method is tested using ideal hydrodynamic simulations of Au+Au collisions at $\sqrt{s_{NN}}=200$ AGeV with the NeXSPheRIO code. Results are in good agreement with experimental data on net-proton and net-charge fluctuations by the STAR collaboration.
