The Quark Gluon Plasma discovered at the Relativistic Heavy Ion Collider (RHIC) and now also studied at the Large Hadron Collider (LHC), has incredible properties due to its strongly interacting nature. This award will fund studies of these strong interactions using very high energy versions of X-rays called direct photons, produced in the same collisions, that can penetrate the plasma and can thus provide important information. These photons can be compared with quarks produced at similar high energies but which should interact more strongly, like the other quark constituents of the plasma. In the project this will be done through studying correlations between photons and hadrons, which are particles made of quarks. Measurements of these correlations will be performed primarily using the PHENIX experiment at RHIC. The specific goal of these analysis studies will be understanding the newly discovered enhancement of a certain type of particle produced by the above mentioned quarks because of the plasma, at both RHIC with PHENIX and also at the ATLAS experiment at the LHC. For this reason our data analysis will include comparisons to, and some limited research activities using, the ATLAS experiment as well. In addition to these analysis projects, the investigator's group at Ohio University will support the upgrade of computing, analysis, hardware of PHENIX through operation of the PHENIX Sub-Detector called the Lead-Glass Calorimeter Detector as well as through leadership of groups and projects of detector development and analysis. The project results in a number of broad benefits to society beyond the important goal of educating and training students. The PI maintains organizations in the state of Ohio and beyond to exchange Heavy Ion knowledge. International collaboration among nuclear physicists around the world is strengthened. Furthermore, the project contributes to the development of future computing in the nation. Finally the investigator contributes to the improvement of physics teaching related to the above research at Ohio University and in the Appalacian region by developing "Active Learning" classroom techniques.

夸克胶子等离子体是在相对论重离子对撞机（RHIC）上发现的，现在也在大型强子对撞机（LHC）上进行研究，由于其强相互作用的性质，它具有令人难以置信的特性。 该奖项将资助这些强相互作用的研究，这些强相互作用使用非常高能量的X射线，称为直接光子，在相同的碰撞中产生，可以穿透等离子体，从而提供重要的信息。 这些光子可以与以类似高能量产生的夸克进行比较，但它们应该像等离子体的其他夸克成分一样，相互作用更强烈。 在该项目中，这将通过研究光子和强子之间的相关性来完成，强子是由夸克组成的粒子。 这些相关性的测量将主要使用RHIC的PHENIX实验进行。 这些分析研究的具体目标将是了解在RHIC与PHENIX以及在LHC的ATLAS实验中，由于等离子体而由上述夸克产生的某种类型的粒子的新发现的增强。 出于这个原因，我们的数据分析将包括比较，以及一些有限的研究活动使用，ATLAS实验以及。 除了这些分析项目外，俄亥俄州大学的研究小组还将通过运行名为铅玻璃量热计探测器的PHENIX子探测器，以及通过领导探测器开发和分析的小组和项目，支持PHENIX的计算、分析和硬件升级。 除了教育和培训学生这一重要目标之外，该项目还为社会带来了许多广泛的好处。 PI在俄亥俄州及其他地区设有组织来交流重离子知识。 世界各地核物理学家之间的国际合作得到加强。 此外，该项目有助于国家未来计算的发展。 最后，研究者通过发展“主动学习”课堂技术，为改善俄亥俄州大学和阿巴拉契亚地区与上述研究相关的物理教学做出了贡献。
