论文摘要
Q-肿瘤剂的方法是研究高能核碰撞中方位角各向异性细节的精细细节的强大工具。本文提出了一种基于数学诱导的新方法，以评估高阶Q肿瘤剂的分析形式。通过使用椭圆形电源分布模拟粒子的各向异性发射的玩具模型来证明该方法的能力，该模型用傅立叶流谐波V_ {N}量化。该方法可以帮助研究将来可以收集的大量事件统计数据，并允许测量V_ {2}分布的非常高的中央矩。这反过来又可以促进理解初始几何形状的进展，对高能量核碰撞中介质扩张的流体动力计算的输入以及其上的约束。
The method of Q-cumulants is a powerful tool to study the fine details of azimuthal anisotropies in high energy nuclear collisions. This paper presents a new method, based on mathematical induction, to evaluate the analytical form of the high-order Q-cumulants. The ability of this method is demonstrated via a toy model that uses the elliptic power distribution to simulate anisotropic emission of particles, quantified in terms of Fourier flow harmonics v_{n}. The method can help in studying the large amount of event statistics that can be collected in the future, and to allow measurements of very high central moments of the v_{2} distribution. This can in turn facilitate progress in understanding the initial geometry, input to hydrodynamic calculations of medium expansion in high energy nuclear collisions, as well as constraints on it.
