论文摘要
高亮度LHC升级的CMS和ATLAS触发系统中基于硬件的轨道重建将提供独特的功能。概述了强子面带的早期轨道触发系统，尤其是针对Tevatron CDF和D0实验的概述。我们讨论了CMS和ATLAS实验的计划，以实现高亮度LHC的基于硬件的轨道重建。特别关注升级的CMS实验的轨道触发能力。我们讨论了这项小说的挑战和机遇，并回顾其实施的替代方案以及讨论预期的绩效。 CM和ATLAS的计划的轨道触发系统具有不同的目标，我们比较和对比两种方法。
Hardware-based track reconstruction in the CMS and ATLAS trigger systems for the High-Luminosity LHC upgrade will provide unique capabilities. An overview is presented of earlier track trigger systems at hadron colliders, in particular for the Tevatron CDF and D0 experiments. We discuss the plans of the CMS and ATLAS experiments to implement hardware-based track reconstruction for the High-Luminosity LHC. Particular focus is placed on the track trigger capability of the upgraded CMS experiment. We discuss the challenges and opportunities of this novel handle, and review the alternatives that were considered for its implementation as well as discuss the expected performance. The planned track trigger systems for CMS and ATLAS have different goals, and we compare and contrast the two approaches.
