论文摘要

在本文中,我们根据多相传输(AMPT)模型仿真提出了一种新颖的事件形状累积物(ESC)响应方法,以分析$ \ sqrt {s_ {nn}} $ = 5.02 tev处的p-pb碰撞。我们发现,最终谐波的子集累积物$ v_ {2} \ {2k \}〜(k = 1,2,3,4)$与初始偏心率$ \ varepsilon_ {2} \ {2k {2k \} $的累积累积在EST基础中是显着增强的。这些Pearson系数强烈依赖于带电的多重性,事件的设定数量(SNE),并且仅依赖于多粒子累积剂(两个粒子,四粒子等)的顺序。我们的结果表明,ESC方法可以抑制事件的波动。

In this paper, we present a novel event-shaped cumulants (ESC) response approach, based on a multi-phase transport (AMPT) model simulations, to analyze p-Pb collisions at $\sqrt{s_{NN}}$= 5.02 TeV. We find that the Pearson coefficients between the subset cumulants of the final harmonics $v_{2}\{2k\}~(k=1,2,3,4)$ and the subset cumulants of initial eccentricity $\varepsilon_{2}\{2k\}$ in the ESC basis are significantly enhanced. These Pearson coefficients are strongly-dependent on the charged multiplicity, the set number of events (SNE), and only weakly-dependent on the order of the multi-particle cumulants (two-particles, four-particles, and so on). Our results show that the ESC method can suppress the event-by-event fluctuations.
