Abstract:

A search for new heavy particles decaying to pairs of vector bosons is presented using data from the CMS detector corresponding to an integrated luminosity of

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

collected at a centre-of-mass energy of

\sqrt{s}=13~\mathrm{TeV}

in 2016. One

W

boson is required to decay to

e\nu

or

\mu\nu

, while the other boson is reconstructed as a single massive jet with substructure compatible with that of a highly-energetic

q \bar{q}^{(')}

pair from a

W

or

Z

boson decay. The search is performed in the resonance mass range between

1.0

and

4.5~\mathrm{TeV}

. No significant deviations from the background only hypothesis are observed in the range of the search. 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 spin-2 bulk graviton and heavy vector triplet models,

WW

resonances lighter than

1~\mathrm{TeV}

and

WZ

resonances lighter than about

3~\mathrm{TeV}

, respectively, are excluded at

95\%

confidence level.
