在RHIC中观察到的对称相关性

Symmetric correlations as seen at RHIC

Adam Bzdak

摘要:

我们分析了由STAR测量的前向-后向多重性相关系数。结果表明,在最中心的Au+Au碰撞中,在η= 0附近对称分布的、赝快度间隔较大的仓比间隔较小的、非对称分布的仓具有更强的相关性。在质子-质子碰撞中,观察到相反的效果。这表明在p+p碰撞和Au+Au碰撞中,两粒子关联随赝快度和的变化具有不同的性质.

英文摘要:

We analyze the forward-backward multiplicity correlation coefficient as measured by STAR. We show that in the most central Au+Au collisions bins located symmetrically around η= 0 with large separation in pseudorapidity are more strongly correlated than bins located asymmetrically with smaller separation. In proton-proton collisions the opposite effect is observed. It suggests a qualitatively different behavior of the two-particle correlation as a function of pseudorapidity sum in p+p and Au+Au collisions.
