sPHENIX试验中轨道重建的要求、状况和计划

Requirements, Status, and Plans for Track Reconstruction at the sPHENIX Experiment

Joseph D. Osborn

摘要:

sPHENIX是布鲁克海文国家实验室的相对论重离子对撞机上正在建造的一个新实验。sPHENIX的主要物理目标是测量$p$ $+$ $p$、$p$ +Au和Au+Au碰撞中的喷流、它们的亚结构和上升共振。为了实现这些目标,将使用由时间投影室和几个硅探测器组成的跟踪系统来识别对应于喷流和上升衰变的轨道。然而,sPHENIX实验将利用有限大小的计算中心收集大约200 PB的数据;因此,由于重离子碰撞的大量占用,及时执行轨道重建是一个挑战。讨论了sPHENIX实验、其航迹重建以及在sPHENIX软件栈中实现更快的航迹拟合算法(例如由通用跟踪软件包提供的算法)的需要。

英文摘要:

sPHENIX is a new experiment that is being constructed at the Relativistic Heavy Ion Collider at Brookhaven National Laboratory. The primary physics goals of sPHENIX are to measure jets, their substructure, and the upsilon resonances in $p$$+$$p$, $p$+Au and Au+Au collisions. To realize these goals, a tracking system composed of a time projection chamber and several silicon detectors will be used to identify tracks that correspond to jets and upsilon decays. However, the sPHENIX experiment will collect approximately 200 PB of data utilizing a finite-sized computing center; thus, performing track reconstruction in a timely manner is a challenge due to the large occupancy of heavy-ion collisions. The sPHENIX experiment, its track reconstruction, and the need for implementing faster track -fitting algorithms, such as that provided by the A Common Tracking Software package, into the sPHENIX software stack are discussed.
