Description
The excellent performance of the Compact Muon Solenoid (CMS) experiment at the LHC has made a number of key observations in the exclusive processes and hence probing the Standard Model (SM) in a unique way. This presentation will review recent results on the measurement of Exclusive processes using the data recorded by the CMS detector. Evidence for light-by-light scattering in ultraperipheral PbPb collisions at a center-of-mass energy per nucleon pair of 5.02 TeV is reported. Exclusive 𝜌(770)0 photoproduction is measured for the first time in pPb collisions. The exclusive photoproduction of Y(nS) meson states from protons is studied in pPb collisions at a center-of-mass energy of 5.02 TeV. Exclusive pipi production is studied in
proton-proton collisions. Low-mass meson resonances are observed in the invariant mass
distribution of pion pairs.
