  A search for new heavy resonances decaying to pairs of bosons (WW, WZ, or WH)
is presented. The analysis uses data from proton-proton collisions collected
with the CMS detector at a center-of-mass energy of 13 TeV, corresponding to an
integrated luminosity of 137 fb$^{-1}$. One of the bosons is required to be a W
boson decaying to an electron or muon and a neutrino, while the other boson is
required to be reconstructed as a single jet with mass and substructure
compatible with a quark pair from a W, Z, or Higgs boson decay. The search is
performed in the resonance mass range between 1.0 and 4.5 TeV and includes a
specific search for resonances produced via vector boson fusion. The signal is
extracted using a two-dimensional maximum likelihood fit to the jet mass and
the diboson invariant mass distributions. No significant excess is observed
above the estimated background. Model-independent upper limits on the
production cross sections of spin-0, spin-1, and spin-2 heavy resonances are
derived as functions of the resonance mass and are interpreted in the context
of bulk radion, heavy vector triplet, and bulk graviton models. The reported
bounds are the most stringent to date.
