Abstract: The physics reach of the LHC can be extended by detecting events in which the beam protons interact via the gamma-gamma or gluon-gluon process and remain intact. Since there is no "underlying event" background from the breakup of the protons, which occurs in typical proton interactions, this central exclusive production (CEP) mode can be used as an experimentally clean way to observe many new physics channels, such as a low-mass SUSY lepton, the Higgs boson, and anomalous production of W and Z boson pairs and to study hard-diffractive QCD physics. I will describe the upgrade effort of the CMS detector at the LHC to detect the off-momentum protons produced by these exclusive events and the expected physics performance.
