在PHENIX上的两粒子相关测量

Two particle correlation measurements at PHENIX

Takahito Todoroki

摘要:

相对论性重离子碰撞中两粒子方位角关联的测量是研究硬散射部分子与热重介质相互作用的有用工具。与触发粒子选择相对于二阶事件平面的相关性是敏感的部分子能量损失的路径长度依赖性和高和中间横向动量对射流的介质的影响,分别。为了研究部分子-介质耦合,获得抑制高次谐波流贡献的关联也是至关重要的。本文给出了PHENIX测量的$\sqrt{s_{NN}}=200$ GeV的Au+Au碰撞中的二阶事件平面相关关联以及排除高次谐波流贡献的关联的结果。

英文摘要:

Measurements of two particle azimuthal correlations in relativistic heavy ion collisions are useful tools to dissect the interplay between hard-scattered partons and hot dense medium. Correlations with trigger particle selection relative to second order event plane are sensitive to the path-length dependence of parton energy loss and to the influence of the medium on jet for high and intermediate transverse momenta pairs, respectively. To study the parton-medium coupling, it is also crucial to obtain correlations with rejection of contributions from higher harmonic flow. We present current results of second order event plane dependent correlations as well as correlations in which contributions from higher harmonic flow have been excluded in Au+Au collisions at $\sqrt{s_{NN}}=200$ GeV measured by PHENIX.
