The discovery of the Higgs boson by the ATLAS and CMS experiments at the LHC has led to a new set of questions regarding the completeness of the Standard Model (SM). Various different theoretical scenarios have been proposed to alleviate the fine-tuning of the SM required by the measured value of the Higgs boson mass, by introducing new physics at the TeV scale, within reach of the LHC. The associated new resonances can be expected to couple to the massive SM bosons. Therefore, final states composed of vector bosons and/or Higgs bosons are potential windows into physics beyond the SM. In this presentation, the latest search results from the ATLAS experiment are shown, targeting diboson final states. Results with the LHC 2015+2016 proton-proton dataset at sqrt(s) = 13 TeV are shown, as well as recent results including 2017 data.
