RUI: Probes for Relativistic Heavy Ion Collisions

在布鲁克海文国家实验室的相对论重离子对撞机和欧洲核子研究中心的大型强子对撞机上进行的重离子实验中，为物理学提供解释的理论支持对于夸克-胶子等离子体（QGP）可能形成的实验研究至关重要。在提出诸如QGP之类的新物理之前，需要对传统机制进行充分的研究和理解。这一建议涉及粒子产生的物理学和这些核碰撞中的集体核效应。在核介质中产生的强相互作用粒子的电磁探针是主要研究者选择的工具。希望这项工作将使人们能够将提出的QGP信号与在这些碰撞产生的高温和密集环境中发生的所有其他复杂的强子现象分开。

0098760HaglinTheoretical support offering interpretations of the physics in heavy-ion experiments carried out at the relativistic heavy ion collider at Brookhaven National Laboratory and planned at the LHC at CERN is crucial to the experimental study of the possible formation of a quark-gluon plasma (QGP). Conventional mechanisms need to be studied and understood fully before claiming new physics such as QGP. This proposal concerns the physics of particle production and collective nuclear effects in these nuclear collisions. Electromagnetic probes of strongly interacting particles produced within the nuclear medium are the tools of choice of the Principal Investigator. It is hoped that this work will enable one to separate the proposed QGP signals from the all the other complicated hadronic phenomena that occur in the hot and dense environment created in these collisions.
