Search for a heavy resonance decaying into a Z boson and a vector boson in the νν¯ q q ¯ final state
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...

| Summary: | 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 13 TeV, corresponding to a total integrated luminosity of
35.9 fb−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% confidence
level on production cross sections are set at 0.9 fb (63 fb) for spin-1 W0
bosons, included
in the heavy vector triplet model, with mass 4.0 TeV (1.0 TeV), and at 0.5 fb (40 fb) for
spin-2 bulk gravitons with mass 4.0 TeV (1.0 TeV). Lower limits are set on the masses of
W
0
bosons in the context of two versions of the heavy vector triplet model of 3.1 TeV and
3.4 TeV, respectively. |
