Relativistic Heavy Ion Theory

这项研究旨在了解日内瓦大型强子对撞机(LHC)和纽约相对论重离子对撞机(RHIC)上令人兴奋的一系列实验。两个粒子关联测量和相关涨落研究可以揭示单个粒子可观测性不能测量的关于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项创新计划上，该计划旨在开发用于分析流体动力学背景下的相关性的理论工具。将这一框架应用于横向动量起伏数据，已经提供了剪切粘度的第一个估计。RHIC实验显示了一个显著的增强相关性的“脊”，引起了人们的极大兴趣。无论有没有喷流触发，这个山脊都会出现，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的这种情况。这些努力有望揭示粒子产生的早期阶段--冰盖--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推动的。与这些实验人员的密切合作使这个理论小组处于理解和影响此类分析的绝佳位置。对撞机RHIC和LHC将原子核撞击在一起，产生了一种名为夸克-胶子等离子体的微小而短暂的基本粒子汤。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质量对撞机上看到的情况。我特别兴奋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。

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.
