CAREER:Probing the Quark Gluon Plasma with Jet Tomography

根据质子和中子如何形成原子核的基本理论，这些粒子预计会在相对论重离子碰撞中产生的高密度和高温度下熔化成夸克和胶子的汤汤，称为夸克胶子等离子体(QGP)。在布鲁克海文国家实验室的相对论重离子对撞机(RHIC)上，发现了一种新的物质相。大型强子对撞机(LHC)以其前所未有的能量覆盖范围，探索了这种相变的新领域，并将揭示其特征。PI的研究通过对内部探测的研究，定量地研究了这种新的物质状态在高密度和高温度下的性质。智力上的优点：喷流是硬分散的夸克和胶子的衰变产物的准直喷雾。因为它们的预期产额是可以使用众所周知的强相互作用理论来计算的，所以它们提供了QGP的校准探针。由于它们在QGP中的传播受强相互作用的影响，喷流的能量损失测量是研究这种新物质状态的关键特征的理想探测器。PI在罗格斯大学的研究小组将利用大型强子对撞机上的紧凑型Muon螺线管(CMS)实验，通过各种免费的喷注测量来确定这种稠密而炎热的物质的基本性质。更广泛的影响：PI提出了一个三层方法，通过整合积极的研究和教育来培养多样化和有竞争力的劳动力。她将鼓励女初中生和高中生在STEM领域继续接受大学教育，方法是将她们带到罗格斯大学进行全天的演示和实验，通过将尖端的大型强子对撞机研究纳入她的物理入门课程和在罗格斯大学组织女性物理会议来招收物理学专业的本科生，并指导女性和少数族裔学生并将她们纳入研究的所有阶段。

According to the fundamental theory of how protons and neutrons form atomic nuclei, these particles are expected to melt into a soup of quarks and gluons known as the quark gluon plasma (QGP) at the high densities and temperatures that are created in relativistic heavy ion collisions. At the Relativistic Heavy Ion Collider (RHIC) at Brookhaven National Laboratory, a new phase of matter has been discovered. With its unprecedented reach in energy, the Large Hadron Collider (LHC) explores new regions of this phase transition and will reveal its signatures. The PI's research investigates the properties of this new state of matter at high density and temperature in a quantitative manner through a study of internal probes.Intellectual Merit: Jets are collimated sprays of decay products of hard-scattered quarks and gluons. Because their expected yields are calculable using the well understood theory of strong interactions, they provide calibrated probes of QGP. Since their propagation through the QGP is affected by strong interactions, an energy loss measurement of jets is an ideal probe to study the key features of this new state of matter. The PI's research group at Rutgers will determine the fundamental properties of this dense and hot matter via various complimentary jet measurements by utilizing the Compact Muon Solenoid (CMS) experiment at LHC. Broader impacts:The PI proposes a three-tiered approach to cultivate a diverse and competitive work force via integration of active research and education. She will encourage female middle and high school students to pursue university education in STEM fields by bringing them to Rutgers for full-day sessions of demos and experiments, recruit undergraduate physics majors by incorporating cutting-edge LHC research into her introductory physics courses and by organizing Women in Physics Conferences at Rutgers, and mentor women and minority students and include them in all phases of research.
