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.

一个公认的事实是，质子和中子由称为夸克和胶子的较小成分组成。 在使用两个重核的碰撞中，形成了一种新的物质状态，称为Quark-Gluon等离子体（QGP）。 该项目将回答有关QGP的基本问题，例如物质如何从质子和中子的集合转变为一个自由状态，在这种状态下，Quark和Gluons可以不受阻碍地穿越太空，就像在大爆炸之后的原始汤中所做的那样。该提议的目的是在QGP的动力学中，在这种媒介中传播的高速夸克。 这提供了有关在这种独特物质状态下夸克和胶子流动的更多信息。这项研究将使用爱丽丝探测器在欧洲核研究组织（CERN）进行。CERN中重离子计划的重点是在非常高密度的情况下了解物质的行为，对应于大爆炸后的一秒钟的条件，当时存在夸克和Gluon的热媒介。目的是通过相对论动能的核能来重现和研究这些条件。芝加哥州立大学将通过对包含Quarkonia和奇怪颗粒的喷气机的物理分析来为这一努力做出贡献。 这项研究调查了质子 - 普罗顿碰撞中Quarkonia和陌生产生的生产机制，以及Quark-Gluon培养基对铅铅碰撞中喷气能量沉积的反应。该项目还包括对快速相互作用触发器（fit）构建的研发贡献；这项工作将为本科生参与硬件项目的参与提供机会：粒子探测器的开发，测试和调试。
