小系统中多粒子关联的PHENIX结果

PHENIX results on multiparticle correlations in small systems

R. Belmont

摘要:

我们目前的测量2-和4-粒子的相关性在d+金碰撞在四个不同的质心能量:200,62.4,39,和19.6 GeV。这些数据是在2016年由RHIC的PHENIX实验收集的。粒子方位分布的第二傅立叶系数$v_2$使用Q-累积量方法测量作为事件多重性的函数。结果给出了一个强有力的指示集体行为下降到最低的能量。

英文摘要:

We present measurements of 2- and 4-particle correlations in d+Au collisions at four different center-of-mass energies: 200, 62.4, 39, and 19.6 GeV. The data were collected in 2016 by the PHENIX experiment at RHIC. The second Fourier coefficient $v_2$ of the particle azimuthal distributions is measured using the Q-cumulant method as a function of event multiplicity. The results give a strong indication of collective behavior down to the lowest energy.
