论文摘要
Sphenix是一个新实验，正在布鲁克黑文国家实验室的相对论重离子对撞机建造。 SPHENIX的主要物理目标是测量喷气机，它们的子结构以及$ P $$+$$ P $，$ p $+au和au+au collisions中的UPSILON共鸣。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与喷气机和Upsilon衰变相对应的音轨。但是，SPHENIX实验将利用有限尺寸的计算中心收集大约200 pb的数据。因此，由于重型离子碰撞的占用很大，及时进行轨道重建是一个挑战。讨论了SPHENIX实验，其轨道重建以及实现更快的曲目 - 适合算法的需求，例如通用跟踪软件包提供的算法，例如，在SPHENIX软件堆栈中进行了。
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.
