随着高亮度大型强子对撞机（HL-LHC）紧凑型介子螺线管（CMS） 1级触发器的跟踪信息的计划增加，触发算法可以完全重新定义。我们探索了在硬件触发水平上使用粒子流重建和每粒子堆积识别（PUPPI）堆积缓解的可行性。这为HL-LHC提出了一种新型的多子探测器模式识别挑战。我们提出了在HL-LHC时代CMS使用的原型算法的物理和硬件资源性能的原理验证研究。
With the planned addition of tracking information to the Compact Muon Solenoid (CMS) Level-1 trigger for the High-Luminosity Large Hadron Collider (HL-LHC), the trigger algorithms can be completely reconceptualized. We explore the feasibility of using particle flow-like reconstruction and pileup per particle identification (PUPPI) pileup mitigation at the hardware trigger level. This represents a new type of multi-subdetector pattern recognition challenge for the HL-LHC. We present proof-of-principle studies on both physics and hardware-resource performance of a prototype algorithm for use by CMS in the HL-LHC era.
