假设高斯波动,解开各向异性流、流波动和非流的可能性
Possibility to disentangle anisotropic flow, flow fluctuation, and nonflow assuming Gaussian fluctuations
摘要:
我们建议的可能性,解开各向异性流,流量波动,和nonflow使用两个,四个和六个粒子的方位角矩假设高斯波动。我们表明,这种解纠缠是可能的,当流量波动很大,相当于平均流量大小。当波动很小时,解纠缠变得困难。我们验证了我们的结果与玩具模型蒙特卡罗模拟。
英文摘要:
We suggest the possibility to disentangle anisotropic flow, flow fluctuation, and nonflow using two-, four-, and six-particle azimuthal moments assuming Gaussian fluctuations. We show that such disentanglement is possible when the flow fluctuations are large, comparable to the average flow magnitude. When fluctuations are small, the disentanglement becomes difficult. We verify our results with a toy-model Monte Carlo simulation.
