Search for heavy mass diboson resonances in the ATLAS experiment

Searches for high mass resonances decaying in a couple of vectorial bosons ($Z$ or $W$) are presented. The results refer to an integrated luminosity of 36.1 fb$^{-1}$ recorded with the ATLAS detector in 2015–2016 at $\sqrt{s}$ = 13 TeV at the Large Hadron Collider. Final states in which one boson decays in leptons and the other one decays in hadrons are considered. Also fully hadronic final states are considered. These results are interpreted within the context of Standard Model extensions with additional Higgs bosons, a heavy vector triplet or warped extra dimensions.
