Search for high-mass exclusive yy -> WW and yy -> ZZ production in proton-proton collisions at = 13 TeV

Abstract: A search is performed for exclusive high-mass ?? ? WW and ?? ? 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 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 ? pWWp and pp ? 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 < ? < 0.20. The results are interpreted as new limits on dimension-6 and dimension-8 anomalous quartic gauge couplings.
