This award will support the study of collisions between ultra-relativistic nuclei, ultimately leading to a determination of the properties and of the equation of state of nuclear matter over a wide range of temperatures and densities. High energy density physics is a rapidly growing field that spans a broad range of physics sub-disciplines including nuclear physics, plasma physics, laser physics, fluid dynamics, and magnetohydrodynamics. The astrophysics results from new terrestrial and orbital observatories have enabled study of high energy density physics on the stellar, galactic, and universal scales through the study of giant planets, brown dwarfs, white dwarfs, neutron stars, supernovae, gamma-ray bursters, and the big bang. The studies supported by this award of relativistic nucleus-nucleus collisions probe the high-temperature region of high energy density physics phase space, where there is a transition from hadron to partonic matter, the quark-gluon plasma (QGP). Although it is clear that dense quark matter is created in the early stages of relativistic heavy-ion collisions, identification of the phase transition boundary will require a comprehensive and correlated set of measured collision observables, as well as, realistic and extensive calculations which relate the observables to nuclear matter parameters.For the next three years, efforts will be focused on the acquisition, analysis, and interpretation of data taken with the Solenoidal Tracker At RHIC (STAR) experiment at the Relativistic Heavy Ion Collider (RHIC) at Brookhaven National Laboratory (BNL) on Long Island, and the Compact Muon Solenoid (CMS) experiment at the Large Hadron Collider (LHC) at the European Center for Nuclear Research (CERN) in Geneva, Switzerland. Junior scientists will also participate in an essential way in this research.

该奖项将支持超相对论原子核之间碰撞的研究，最终确定核物质在广泛的温度和密度范围内的性质和状态方程。 高能量密度物理学是一个快速发展的领域，涵盖广泛的物理学子学科，包括核物理学、等离子体物理学、激光物理学、流体动力学和磁流体动力学。 新的地面和轨道天文台的天体物理学结果使得通过研究巨行星、棕矮星、白矮星、中子星、超新星、伽马射线暴和宇宙尺度的高能量密度物理学研究成为可能。大爆炸。 该奖项支持的相对论核-核碰撞研究探索了高能量密度物理相空间的高温区域，其中存在从强子到粒子物质（夸克-胶子等离子体（QGP））的转变。 尽管很明显，稠密夸克物质是在相对论性重离子碰撞的早期阶段产生的，但相变边界的识别将需要一组全面且相关的测量碰撞观测值，以及与未来三年，工作重点将集中在相对论重离子对撞机的 RHIC (STAR) 螺线管跟踪器实验所获取的数据的采集、分析和解释上长岛布鲁克海文国家实验室 (BNL) 的 RHIC 实验，以及瑞士日内瓦欧洲核研究中心 (CERN) 大型强子对撞机 (LHC) 的紧凑介子螺线管 (CMS) 实验。 青年科学家也将以重要的方式参与这项研究。
