Search for high-mass exclusive $\gamma \gamma$ $\to$ WW and $\gamma \gamma$ $\to$ ZZ production in proton-proton collisions at $\sqrt{s}$ = 13 TeV

Abstract

A search is performed for exclusive high-mass $\gamma \gamma$ $\to$ WW and $\gamma \gamma$ $\to$ ZZ production in proton-proton collisions using intact forward protons reconstructed in near-beam detectors, with both weak bosons decaying into boosted and merged jets. The analysis is based on a sample of proton-proton collisions collected by the CMS and TOTEM experiments at $\sqrt{s}$ = 13 TeV, corresponding to an integrated luminosity of 100 fb${}^{-1}$. No excess above the standard model background prediction is observed, and upper limits are set on the pp $\to$ pWWp and pp $\to$ pZZp cross sections in a fiducial region defined by the diboson invariant mass $m$(VV) $<$ 1 TeV (with V = W, Z) and proton fractional momentum loss 0.04 $<$ $\xi$ $<$ 0.20. The results are interpreted as new limits on dimension-6 and dimension-8 anomalous quartic gauge couplings.
