Relativistic Heavy Ion Collision Studies at the LHC and RHIC

由俄亥俄州州立大学相对论重离子小组利用国家科学基金会的现有资金进行的研究是在RHIC和LHC装置上分别用星星和ALICE实验进行高能重离子和质子碰撞的实验研究。主要的重点将是使用Hanbury-Brown-Twiss干涉测量法，利用相同的玻色子对，如π介子和K介子对，从这些碰撞中提取时空信息。利用研究人员开发的模型，这些实验信息将与碰撞的动力学相关，以帮助确定这些碰撞中的强子化机制，这可能是夸克物质形成等奇异过程的标志。这项研究的更广泛影响主要是1）培训年轻科学家进行大规模合作研究的方法，2）推广大规模网格计算方法，对大数据集进行数据分析。

The research to be carried out with the present NSF funding by the Ohio State University Relativistic Heavy Ion group is to carry out experimental studies of high-energy heavy-ion and proton collisions at both the RHIC and LHC facilities with the STAR and ALICE experiments, respectively. The main emphasis will be to use the method of Hanbury-Brown-Twiss interferometry to extract space-time information from these collisions using identical boson pairs such as pion and kaon pairs. Using models developed by the investigators this experimental information will be related to the dynamics of the collision to help determine the mechanism of hadronization in these collisions, which might serve as a signature for exotic processes such as Quark Matter formation.The broader impacts of this research are mainly 1) to train young scientists in the methods of large-scale collaborative research, and 2) to further the methods of large-scale grid computing to carry out data analysis on large data sets.
