Abstract:
This paper describes a search for new heavy diboson resonances decaying to the 22q2\ell2\text{q} final state, with two charged leptons (=e,μ\ell=e,\mu) produced by the decay of a Z\text{Z} boson, and two quarks produced by the hadronic decay of a W\text{W} or Z\text{Z} boson. The search is performed for resonance masses from 400400 to 4500 GeV4500~\text{GeV}. Two categories are defined based on the merged or resolved reconstruction of the hadronically decaying vector boson, optimized for high- and low-mass resonances respectively. The search is based on data collected during 2016 by the CMS experiment at the LHC in proton-proton collisions with a center-of-mass energy of s=13 TeV\sqrt{s}=13~\text{TeV}, corresponding to an integrated luminosity of 35.9 fb135.9~\text{fb}^{-1}. Upper limits on the production cross section of heavy spin-1 and spin-2 resonances are derived as a function of the resonance mass, and exclusion limits of W’\text{W'} and bulk graviton particles are produced in the framework of the heavy vector triplet model and warped extra dimensions, respectively.
