In this RUI (Research in Undergraduate Institutions) renewal proposal, the PIproposes to undertake two new projects, i.e., (1) development and application of atransport theory with Bose-Einstein statistics for ultra-relativistic heavy-ion collisionsat Brookhaven's Relativistic Heavy-Ion Collider (RHIC) and (2) investigations of nov-el properties of dense neutron-rich matter with energetic radioactive beams. The largenumber of pions produced and thus the high value of pion phase-space density reachedin heavy-ion collisions at RHIC requires a proper inclusion of the Bose-Einstein s-tatistics (multi-boson symmetrization) in the reaction dynamics. The Bose-Einsteinstatistics is currently neglected in essentially all dynamical models for RHIC. Thefocus of the PI's work on the first project is to include the Bose-Einstein statisticsin both the hadronization and the subsequent dynamical evolution of hadrons, mostimportantly pions, within a multi-phase transport model. The transport theory withBose-Einstein statistics will be a useful tool for predicting reliably and interpretingcritically nuclear collision data at RHIC, especially the single-particle spectra, multi-particle correlation functions and the collective ow of pions. It might also beusefulfor solving the Hanbury Brown/Twiss (HBT) puzzle found in experiments at RHIC.The ultimate goals of the second project are to determine accurately the isospindependence of the nuclear equation of state (EOS) and to investigate novel propertiesof dense neutron-rich matter that was not in reach in terrestrial laboratories before.These are important issues identified in the most recent U.S. long-range plan (LRP)for nuclear physics and foundamental properties that govern many aspects of neutronstars. To extract crucial information about the isospin-dependence of the nuclearEOS, the PI proposes to investigate several experimental observables in nuclear reac-tions induced by energetic neutron-rich nuclei at existing radioactive beam facilitiesand the future Rare Isotope Accelerator, identified as the top priority for new con-struction in the U.S. LRP for nuclear physics. Moreover, several novel propertiesof dense neutron-rich matter will be explored. These include the isospin separationinstability, the unique 0

在这项RUI（本科机构的研究）更新建议中，PIPOPOSE进行两个新项目，即（1）使用Bose-Einstein统计数据，用于超偏见的重型离子碰撞的Brookhaven的相对性重型亲核（RhiC）和NOVEN-NOVER-NOVER-NOVER and NOVER rongrion和NOVER rongrion of Novem and Nove-El-El-El-El-El-El-El-El-El-El-En Novem and Novem and NOVER rontron和NOVER的rongrion和NOVER rongrion of Novem and Novem and NOVEN的态度的发展和应用，放射性梁。产生的液化杆菌，因此在RHIC时达到了呈锥形空间密度的高价值，需要在反应动力学中适当地包含Bose-Einstein S-tatistics（多玻色子对称性）。目前，在RHIC的所有动力学模型中，目前都忽略了Bose-Einsteinstatistics。 PI在第一个项目上的工作的组合是将Bose-Einstein Statistices包括在多相运输模型中的强调和随后的Hadron的动力学演变中。用肉体统计的运输理论将是一种有用的工具，用于在RHIC上可靠和解释核碰撞数据，尤其是单粒子光谱，多粒子相关函数和PION的集体OW。在RHIC的实验中发现的汉伯里棕色/TWISS（HBT）难题也可能是有益的。第二个项目的最终目标是准确地确定状态核方程（EOS）的同时依赖性（EOS）（EOS）的同时依赖性（EOS）的同一物质，并研究了较长的核能中的核能和近期范围。控制中子星的许多方面的创建特性。为了提取有关核生物的同胞依赖性的关键信息，PI提议研究在现有的放射性束设备上通过能量富含中子的核引起的核重新核能中的几种实验性观察力，并且未来稀有的同位素加速器，被确定为美国LRP新结构的最高优先级。此外，将探索几种密集的中子物质的新型特性。这些包括isospin saparationstability，唯一0
