摘要:

LHC ALICE实验的μ子谱仪(MS)配备了HLT(高电平触发器),其目的是提高在L0阶段提供的触发切割的准确性。一个实时事件重建的计算挑战是满意的,以实现这一软件触发切割的HLT。在描述了在线算法之后,使用在$\sqrt{s}=7$ TeV处测量的pp碰撞将在线跟踪器的性能与离线跟踪器的性能进行比较。

英文摘要:

The Muon Spectrometer (MS) of the ALICE experiment at LHC is equipped with a HLT (High Level Trigger), whose aim is to improve the accuracy of the trigger cuts delivered at the L0 stage. A computational challenge of real-time event reconstruction is satisfied to achieve this software trigger cut of the HLT. After the description of the online algorithms, the performance of the online tracker is compared with that of the offline tracker using the measured pp collisions at $\sqrt{s}=7$ TeV.
