Search for diboson resonances in the $\nu\nu qq$ final state in $pp$ collisions at $\sqrt{s}=$13 TeV with the ATLAS detector

A search is performed for resonances decaying into $WZ$ or $ZZ$ pairs in proton-proton collision data at a centre-of-mass energy of $\sqrt{s} = 13$ TeV. The analysed data sample corresponds to an integrated luminosity of 3.2 $\textrm{fb}^{-1}$ and was recorded in 2015 with the ATLAS detector at the Large Hadron Collider. The search is performed in the $\nu\nu qq$ final state and the mass range from 1 to 3 TeV is probed. In this mass range the hadronically-decaying vector boson is reconstructed using boosted techniques. No significant deviation above the expected background is observed in data and the results are interpreted using three benchmark models: the Randall-Sundrum model of extra dimensions, the Heavy Vector Triplet model, and a model predicting a heavy Higgs boson.
