ATLAS searches for resonances decaying to boson pairs

Many extensions to the Standard Model predict new particles decaying into two bosons (W, Z, photon, or Higgs bosons) making these important signatures in the search for new physics. Searches for such diboson resonances have been performed in final states with different numbers of leptons, photons, jets and b-jets where new jet substructure techniques to disentangle the hadronic decay products in highly boosted configuration are being used. This document summarizes recent ATLAS searches for resonances decaying to diboson final states, VV, VH and HH with LHC Run 2 data collected.
