摘要：
The CMS experiment implements a sophisticated two-level triggering system composed of a hardware Level-1 and a software High Level Trigger. A new Level-1 trigger architecture with improved performance is now being used to maintain high physics efficiency for the more challenging luminosity conditions experienced during Run II. In this paper, the upgrades to the calorimeter trigger are shown along with performance measured on 2017 collision data. The algorithms for the selection of final states with hadronically decaying r leptons are described. The implementation of the first dedicated Vector Boson Fusion trigger algorithm is presented as well, along with its performance on Higgs physics signals.
