Search for massive resonances decaying into WW, WZ, ZZ, qW and qZ in the dijet final state at $\sqrt{s} = 13~\mathrm{TeV}$

A search for new massive resonances decaying to pairs of W and Z bosons or to a W/Z boson and a quark in the dijet final state is presented. Results are based on data corresponding to an integrated luminosity of $35.9~\mathrm{fb}^{-1}$ recorded in proton-proton collisions at $\sqrt{s} = 13~\mathrm{TeV}$ with the CMS detector at the CERN LHC in 2016. Resonances with masses of at least $1.2~\mathrm{TeV}$ and decaying to WW, WZ, ZZ, qW, or qZ are probed. Cross section and resonance mass exclusion limits are set for various models that predict gravitons, heavy spin-1 bosons and excited quarks. In a heavy vector triplet model ("B"), $\mathrm{W}^\prime$ and $\mathrm{Z}^\prime$ resonances with masses below $3.6$ and $2.7~\mathrm{TeV}$, respectively, are excluded at a confidence level of $95\%$. Similarly, excited quark resonances, $\mathrm{q}^*$, decaying to qW and qZ with masses less than $5.0$ and $4.8~\mathrm{TeV}$, respectively, are excluded. In the narrow-width bulk graviton model, cross section upper limits in the range $\hbox{37.1--0.6}~\mathrm{fb}$ are set.
