ATLAS searches for resonances decaying to boson pairs

Searches for heavy-mass resonances decaying into a couple of vectorial bosons, $WW$, $WZ$ or $ZZ$ using data from proton-proton collisions at a centre-of-mass energy of $\sqrt{s}$ = 13TeV at the Large Hadron Collider are presented. The searches are performed in the semileptonic and fully hadronic final states, in which one boson decays into leptons and the other one decays into hadrons, or both bosons decay hadronically. Semileptonic results refer to an integrated luminosity of 36.1 fb$^{−1}$ recorded with the ATLAS detector in 2015–2016 while the fully hadronic results correspond to the full Run-II statistics, 139 fb$^{−1}$. These results are interpreted within the context of Standard Model extensions with additional Higgs bosons, a heavy vector triplet or warped extra dimensions.
