Omar Silveira Proton reconstruction with the CMS-TOTEM Precision Proton Spectrometer CMS, [TOTEM Collaborations] Hide abstract | Show figures | Show BibTeX | Show discussion | View PDF | 2210.05854v1 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 validated using a sample of (semi)exclusive dilepton events. The performance of PPS has proven the feasibility of continuously operating a near-beam proton spectrometer at a high luminosity hadron collider.
