利用两粒子和三粒子关联探测强相互作用部分子物质

Using two- and Three-particle correlations to probe strongly interacting partonic matter

Wolf G. Holzmann

摘要:

最新的两个和三个粒子的相关测量获得的PHENIX合作。三粒子的相关性是一致的锥形发射模式的存在下的数据。相对于碰撞几何形状的两个粒子的相关性揭示了强大的形状和产量的修改的远离侧喷流,这取决于触发粒子相对于事件平面的取向。在$Δϕ\approx π$和$Δϕ\approx π\pm 1.1$周围的区域中,每次触发产率的几何形状依赖性的差异可以通过射流能量损失和介质对沉积能量的响应的不同几何形状依赖性来理解。

英文摘要:

The latest two- and three-particle correlation measurements obtained by the PHENIX collaboration are presented. Three-particle correlations are consistent with the presence of conical emission patterns in the data. Two-particle correlations relative to the collision geometry reveal strong shape and yield modifications of the away-side jet, that depend on the orientation of the trigger particle with respect to the event plane. A difference in the geometry dependence of the per trigger yields in the regions around $Δϕ\approx π$ and $Δϕ\approx π\pm 1.1$ can be understood by a different geometry dependence of jet energy loss and the medium response to the deposited energy.
