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.

该奖项将支持对超相关核之间碰撞的研究，最终导致确定核问题状态的性质和核物质状态方程。 高能量密度物理学是一个快速增长的领域，涵盖了广泛的物理子学科，包括核物理，血浆物理学，激光物理学，流体动力学和磁性水力动力学。 天体物理学是由新的陆生和轨道观测站引起的，通过研究巨型行星，棕色矮人，白矮人，中子星，超新星，超新星，伽玛 - 雷米钻孔和大型大型大型大型巨型行星，可以研究恒星，银河系和通用尺度上的高能量物理学。 这项相对论核核核碰撞的奖项支持的研究探测了高能量密度物理相位空间的高温区域，那里存在从强子到党派物质的过渡到Quark-Gluon等离子体（QGP）。 尽管很明显，在相对论重离子碰撞的早期阶段创建了密集的夸克物质，但对相过渡边界的识别将需要一组全面且相关的测量碰撞可观察物以及现实和广泛的计算，这些计算将观察到的物品与核问题参数相关。 （Star）在长岛布鲁克黑文国家实验室（BNL）的相对论重离子对撞机（RHIC）的实验，以及位于瑞士日内瓦的欧洲核研究中心（CERN）的大型强子撞机（LHC）的紧凑型MUON电磁阀（CMS）实验。 初级科学家还将参与这项研究的重要方式。
