| Abstract: A search for a new heavy particle decaying to a pair of vector bosons (WW or WZ) is presented using data from the CMS detector corresponding to an integrated luminosity of 35.9 fb$^{-1}$ collected in proton-proton collisions at a centre-of-mass energy of 13 TeV in 2016. One of the bosons is required to be a W boson decaying to $\mathrm{e}\nu$ or $\mu\nu$, while the other boson is required to be reconstructed as a single massive jet with substructure compatible with that of a highly-energetic quark pair from a W or Z boson decay. The search is performed in the resonance mass range between 1.0 and 4.5 TeV. The largest deviation from the background-only hypothesis is observed for a mass near 1.4 TeV and corresponds to a local significance of 2.5 standard deviations. The result is interpreted as an upper bound on the resonance production cross section. Comparing the excluded cross section values and the expectations from theoretical calculations in the bulk graviton and heavy vector triplet models, spin-2 WW resonances with mass smaller than 1.07 TeV and spin-1 WZ resonances lighter than 3.05 TeV, respectively, are excluded at 95% confidence level. | ||

| Summary |
| A search for a new heavy resonance decaying to a pair of vector bosons is performed in events with one muon or electron and a massive jet. Using the $N$-subjettiness ratio ${\tau_{21}}$, massive jets are tagged as highly energetic vector bosons (V = W, Z) decaying to quark pairs. The soft-drop mass is used as an estimate of the V-jet mass. The lepton momentum and missing transverse momentum are used to reconstruct the momentum of the $\mathrm{W} \to \ell \nu$ boson candidate, constraining the invariant mass of the $\ell \nu$ pair to the W boson mass value. A novel signal extraction technique is introduced based on a simultaneous fit of the V-jet mass and the diboson mass, and improves the search sensitivity compared to the method employed in previous versions of this analysis. No significant evidence of a new signal is found. The results are interpreted in terms of upper limits on the production cross section of new resonances decaying to WW and WZ final states. The observed limits for a WW resonance range from 29 fb at 1.3 TeV to 0.32 fb at 4.4 TeV, while for a WZ resonance they range from 84 fb at 1.05 TeV to 0.64 fb at 4.4 TeV. Comparing the excluded cross section values to the expectations from theoretical calculations, spin-2 bulk graviton resonances decaying to WW with mass smaller than 1.07 TeV and W' $ \to $ WZ resonances lighter than 3.05 TeV are excluded at 95% CL. |
