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

I will report a search for heavy resonances beyond the standard model decaying into a ZV (V = Z, W) diboson pair with a final state of dijet (decay from V) plus missing transverse energy ($E_T^{miss}$) due to $Z\rightarrow \nu \nu$. Data used in this analysis is from proton-proton collisions at a centre-of-mass energy of $\sqrt{s}=$ 13 TeV from the Large Hadron Collider, and recorded by the ATLAS detector. The mass range in the search is from 500 to 5000 GeV. In this mass range the hadronically-decaying vector boson is reconstructed using boosted-jet techniques. No resonance is observed in data. In the absence of a deviation from the Standard Model expectation, upper bounds on the new resonance production cross sections times their decay branching ratios to ZV pairs are derived within the context of Standard Model extensions with an extended Higgs sector, a heavy vector triplet and warped extra dimensions.
