Search for new physics in exclusive processes at the Large Hadron Collider

Abstract:
Photon-photon collisions may provide the conditions to study particle production with masses at the electroweak scale. By tagging the leading proton from the hard interaction, the Precision Proton Spectrometer (PPS) provides an increased sensitivity to select exclusive processes and probe the standard model (SM).

PPS is a detector system at approximately 210 m from the interaction point around the CMS detector, and it is designed to perform measurements of e.g. the quartic gauge couplings and search for rare exclusive processes. Since 2016, PPS has been taking data in normal high-luminosity proton-proton LHC collisions.

A search for exclusive processes using data collected by the CMS experiment is performed and the results obtained are presented.
