Many proposed new, heavy particles that could be produced at the LHC , such as a W’ or Graviton, would lead to final states with a pair of high pT vector bosons. The hadronic decay products of these energetic bosons tend to be highly collimated, leading to their decay products forming pairs of boosted hadronic jets. By using large radius jets and exploiting jet substructure techniques to pick the bosonic signal out of the dominant QCD backgrounds, an analysis can take advantage of the high branching fraction (~50%) of the fully hadronic decay channel. In this seminar I will describe the jet-substructure techniques explored by the ATLAS analyses, present the results of the analysis of the 20fb^{-1 of 8TeV ATLAS data and show the preliminary Run-2 result with 3.2fb}-1 of 13TeV ATLAS data.
