dc.description.abstractA search is presented for high-mass exclusive diphoton production via photon-photon fusion in proton-proton collisions at Formula Presented in events where both protons survive the interaction. The analysis utilizes data corresponding to an integrated luminosity of Formula Presented collected in 2016-2018 with the central CMS detector and the CMS and TOTEM precision proton spectrometer (PPS). Events that have two photons with high transverse momenta (Formula Presented), back-to-back in azimuth, and with a large diphoton invariant mass (Formula Presented) are selected. To remove the dominant inclusive diphoton backgrounds, the kinematic properties of the protons detected in PPS are required to match those of the central diphoton system. Only events having opposite-side forward protons detected with a fractional momentum loss between 0.035 and 0.15 (0.18) for the detectors on the negative (positive) side of CMS are considered. One exclusive diphoton candidate is observed for an expected background of 1.1 events. Limits at 95% confidence level are derived for the four-photon anomalous coupling parameters Formula Presented and Formula Presented, using an effective field theory. Additionally, upper limits are placed on the production of axionlike particles with coupling strength to photons Formula Presented that varies from Formula Presented to Formula Presented over the mass range from 500 to 2000 GeV.
