论文摘要
最近对流动角波动的差异性质的研究（称为事件平面向去相关）表明，假设常见对称平面的测量值可能需要考虑流动角波动效应。使用HIJING和AMPT模型，可以表明，使用两种和三凸相关方法获得的流动角波动测量值可能具有与长和短距离非流量相关性相关的显着非流量效应。当前的研究表明，累积方法降低非流量效应的能力。进一步认为，使用四凸相关方法的测量值可用于提供差分流角波动的准确量化。
Recently studies of the differential nature of the flow angle fluctuations, known as event plane angular decorrelation, indicated that measurements that assume a common symmetry plane may need to consider the flow angle fluctuations effect. Using the HIJING and AMPT models, it is shown that the flow angle fluctuations measurements, obtained with the two- and three-subevents correlation method, could have significant non-flow effects associated with long- and short-range non-flow correlations. The current study demonstrates the four-subevents cumulant methods' ability to reduce the non-flow effects. It is further argued that the measurements using the four-subevents correlation method can be used to provide accurate quantification of the differential flow angle fluctuations.
