RUI: Studies of Relativistic Heavy Ions Collisions in ALICE at the LHC

众所周知，质子和中子是由称为夸克和胶子的较小成分组成的。在使用两束重原子核的碰撞中，会形成一种新的物质状态，称为夸克-胶子等离子体(QGP)。这个项目将回答有关QGP的基本问题，例如物质如何从质子和中子的集合转变为自由状态，在这种状态下，夸克和胶子可以畅通无阻地在太空中传播，就像他们在大爆炸后的原始物质汤中所做的那样。这一提议的目的是研究QGP在高速夸克通过该介质时的动力学。这提供了更多关于夸克和胶子在这种独特物质状态下流动的信息。这项研究将在欧洲核子研究组织(CERN)使用爱丽丝探测器进行。CERN重离子计划的重点是了解物质在极高密度下的行为，对应于大爆炸后几分之一秒的条件，当时存在着炎热、致密的夸克和胶子介质。我们的目标是通过相对论动能下的原子核碰撞来重建和研究这些条件。芝加哥州立大学将致力于对含有夸克尼亚和奇异粒子的喷流进行物理分析，从而为这一努力做出贡献。本文研究了质子-质子碰撞中夸克尼亚和奇异性产生的机制，以及铅-铅碰撞中夸克-胶子介质对喷注能量沉积的响应。该项目还包括对快速交互触发器(FIT)建设的研发贡献；这一努力将为本科生参与硬件项目提供机会：粒子探测器的开发、测试和调试。

It is a well-established fact that protons and neutrons are made up of smaller constituents called quarks and gluons. In collisions using two beams of heavy nuclei, a new state of matter is formed, called the quark-gluon plasma (QGP). This project will answer fundamental questions about the QGP, such as how matter is transformed from a collection of protons and neutrons to a free state where quarks and gluons can travel through space unhindered, much like they did in the primordial soup of matter following the Big Bang. The goal of this proposal is to the dynamics of the QGP in the presence of a high-velocity quark traveling through this medium. This provides more information on the flow of quarks and gluons in this unique state of matter. The research will be carried out at the European Organization for Nuclear Research (CERN) using the ALICE detector.The focus of the Heavy Ion program at CERN is to understand the behavior of matter at very high density, corresponding to conditions a fraction of a second after the Big Bang, when a hot, dense medium of quarks and gluons existed. The goal is to recreate and study these conditions via colliding nuclei at relativistic kinetic energies. Chicago State University will contribute to this effort by working on the physics analysis of jets containing quarkonia and strange particles. This study investigates the production mechanism of quarkonia and strangeness production in proton-proton collisions and the response of the quark-gluon medium to jet energy deposition in lead-lead collisions. The project also includes an R&D contribution to the construction of the Fast Interaction Trigger (FIT); this effort will provide opportunities for the involvement of undergraduate students in hardware projects: the developing, testing and commissioning of particle detectors.
