Abstract:

A search is presented for heavy resonances decaying into a Z boson and either a W boson or another Z boson (WZ or ZZ), with one Z boson decaying into a pair of neutrinos and the other boson decaying hadronically into a pair of collimated quarks, which is reconstructed as a highly energetic boosted jet. The search is performed using the data collected by the CMS detector at the CERN LHC during 2016 in proton-proton collisions at a center-of-mass energy of

13~\mathrm{TeV}

, corresponding to a total integrated luminosity of

35.9~\mathrm{fb}^{-1}

. No excess is observed in data with regards to background expectations. Results are interpreted in beyond standard model scenarios. Limits on production cross sections are set in the range 0.8--50

~\mathrm{fb}

for spin-2 bulk gravitons and for W' bosons in the context of the heavy vector triplet (HVT) model. For the two HVT scenarios considered, a W' resonance is excluded at

95\%~\mathrm{CL}

up to a mass of

3.2~\mathrm{TeV}

in the first case and

3.5~\mathrm{TeV}

in the second.
