This research aims to understand the exciting array of experiments at the Large Hadron Collider (LHC) in Geneva and the Relativistic Heavy Ion Collider (RHIC) in New York. Two particle correlation measurements and related fluctuation studies can reveal space-time information about particle production and dynamics not measured by single particle observables. The activity supported by this award centers on an innovative program to develop theoretical tools for the analysis of correlations in a hydrodynamic context. Applications of this framework to transverse-momentum fluctuation data already provide a first estimate of the shear viscosity.RHIC experiments exhibit a striking "ridge" of enhanced correlations that has garnered substantial interest. This ridge occurs both with and without a jet trigger, and is part of a rich correlation landscape. We propose to apply our hydrodynamic framework to understand this landscape at RHIC and LHC. These efforts promise to reveal information on both early stages of particle production - the glasma - as well as the later period of hydrodynamic evolution. This and similar work is driven by data analyzed at Wayne State. Close collaboration with these experimenters puts this theory group in an excellent position to understand and influence such analyses.The colliders RHIC and LHC smash nuclei together, producing a tiny fleeting soup of elementary particles called the quark-gluon plasma. By studying the fluid characteristics of this plasma using mathematical models, we hope to explain what is seen at these massive colliders. I'm especially excited to be sharing this research with disadvantaged students in Detroit through a program aimed at students who are studying to become teachers.

这项研究旨在了解日内瓦的大型强子对撞机（LHC）和纽约的相对论重离子对撞机（RHIC）的令人兴奋的实验阵列。 双粒子相关测量和相关涨落研究可以揭示单粒子观测量无法测量的粒子产生和动力学的时空信息。 该奖项支持的活动集中在一个创新项目上，旨在开发用于分析流体动力学背景下相关性的理论工具。 这个框架的应用程序的横向动量波动数据已经提供了第一个估计的剪切viscosity.RHIC实验表现出惊人的“脊”的增强相关性，已经获得了很大的兴趣。 这个脊在有和没有喷流触发的情况下都会出现，并且是丰富的相关景观的一部分。 我们建议应用我们的流体动力学框架来理解RHIC和LHC的这种景观。这些努力有望揭示粒子产生的早期阶段--玻璃体--以及流体动力学演化的后期阶段的信息。 这项工作和类似的工作是由韦恩州立大学分析的数据驱动的。 与这些实验者的密切合作使这个理论小组处于一个很好的位置来理解和影响这样的分析。RHIC和LHC对撞机将原子核撞在一起，产生一种微小的、转瞬即逝的基本粒子汤，称为夸克-胶子等离子体。 通过使用数学模型研究这种等离子体的流体特性，我们希望解释在这些大型对撞机上看到的情况。 我特别高兴能通过一个针对正在学习成为教师的学生的项目，与底特律的弱势学生分享这项研究。
