  The High-Luminosity Large Hadron Collider (HL-LHC) is designed to achieve
higher instantaneous luminosities, enabling the exploration of the rarest
processes of the Standard Model (SM). The CMS collaboration has published an
Expression of Interest to pursue the study of the central exclusive production
processes, using near-beam detectors. This report details both the expected
performance and the scientific potential of the CMS near-beam proton
spectrometer at the HL-LHC.
