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.

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温度下熔化成夸克和胶子的汤，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。 凭借其前所未有的能量，大型强子对撞机（LHC）探索了这种相变的新区域，并将揭示其特征。 PI的研究通过对内部探针的研究，以定量的方式研究了这种新的物质状态在高密度和高温度下的性质。学术价值：喷流是硬散射夸克和胶子衰变产物的准直喷雾。因为它们的预期产率可以用强相互作用理论计算，所以它们提供了QGP的校准探针。由于它们通过QGP的传播受到强相互作用的影响，因此对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针。罗格斯大学的PI研究小组将利用LHC的紧凑型μ子螺线管（CMS）实验，通过各种免费的射流测量来确定这种致密和热物质的基本性质。更广泛的影响：PI提出了一个三层的方法，通过积极的研究和教育的整合，培养一个多样化和有竞争力的劳动力。 她将鼓励女性初中和高中学生通过将他们带到罗格斯大学进行全天的演示和实验来接受STEM领域的大学教育，通过将前沿的LHC研究纳入她的入门物理课程并通过组织罗格斯大学的女性物理学会议来招募本科物理专业学生，并指导女性和少数民族学生并将其纳入研究的各个阶段。
