摘要

在对大型强子对撞机进行高亮度升级后,CMS Barrel的介子室必须应对每束交叉相互作用数量的增加。因此,新的数据采集和处理算法技术将是必要的,以准备这样一个高堆积的环境。利用机器学习作为解决这一问题的技术,本文重点研究了通过蒙特卡罗模拟获得的数据模型的产生,该模型能够预测穿过CMS桶状μ子腔的μ子的横向动量,并将其与当前CMS 1级触发系统分配的横向动量($p_T$)进行比较。

Development of Machine Learning based muon trigger algorithms for the Phase2 upgrade of the CMS detector
After the high-luminosity upgrade of the LHC, the muon chambers of CMS Barrel must cope with an increase in the number of interactions per bunch crossing. Therefore, new algorithmic techniques for data acquisition and processing will be necessary in preparation for such a high pile-up environment. Using Machine Learning as a technique to tackle this problem, this paper focuses in the production of models - with data obtained through Monte Carlo simulations - capable of predicting the transverse momentum of muons crossing the CMS Barrel muon chambers, comparing them with the transverse momentum ($p_T$) assigned by the current CMS Level-1 trigger system.
