Abstract

Multiparticle cumulants method can be used to reveal long-range collectivity in small and large colliding systems. The four-particle symmetric cumulant

s c_{2, 4} {4}

, three-particle asymmetric cumulant

a c_{2} {3}

, and the normalized cumulants

n s c_{2, 4} {4}

and

n a c_{2} {3}

from the transverse momentum conservation and flow are calculated. The interplay between the two effects is also investigated. Our results are in a good agreement with the recent ATLAS measurements of multiparticle azimuthal correlations with the subevent cumulant method, which provides insight into the origin of collective flow in small systems.

横向动量守恒和流动的对称累积量 sc2,4{4} 和非对称累积量 ac2{3}

多粒子累积量方法可用于揭示小型和大型碰撞系统中的长程集合性。计算了横向动量守恒和流动产生的四粒子对称累积量sc2,4{4}、三粒子不对称累积量ac2{3}以及归一化累积量nsc2,4{4}和nac2{3}。我们还研究了这两种效应之间的相互作用。我们的结果与最近 ATLAS 用子事件累积法测量多粒子方位相关性的结果非常吻合，这为洞察小系统中集体流动的起源提供了依据。
