Search for a heavy resonance decaying into a Z boson and a vector boson in the vvqq final state

Abstract

A search is presented for a heavy resonance decaying into either a pair of Z bosons or a Z boson and a W boson (ZZ or WZ), with a Z boson decaying into a pair of neutrinos and the other boson decaying hadronically into two collimated quarks that are reconstructed as a highly energetic large-cone jet. The search is performed using the data collected with the CMS detector at the CERN LHC during 2016 in proton-proton collisions at a center-of-mass energy of 13TeV, corresponding to a total integrated luminosity of 35.9 fbð€€€1. No excess is observed in data with regard to background expectations. Results are interpreted in scenarios of physics beyond the standard model. Limits at 95% con dence level on production cross sections are set at 0.9 fb (63 fb) for spin-1 W 0 bosons, included in the heavy vector triplet model, with mass 4.0TeV (1.0TeV), and at 0.5 fb (40 fb) for spin-2 bulk gravitons with mass 4.0TeV (1.0TeV). Lower limits are set on the masses of W 0 bosons in the context of two versions of the heavy vector triplet model of 3.1TeV and 3.4TeV, respectively.
