This paper reports on a search for narrow resonances in diboson production in the ℓℓqq̅ final state using pp collision data corresponding to an integrated luminosity of 20 fb⁻¹ collected at √s̅ = 8 TeV with the ATLAS detector at the Large Hadron Collider. No significant excess of data events over the Standard Model expectation is observed. Upper limits at the 95% confidence level are set on the production cross section times branching ratio for Kaluza-Klein gravitons predicted by the Randall-Sundrum model and for Extended Gauge Model W' bosons. These results lead to the exclusion of mass values below 740 and 1590 GeV for the graviton and W' boson respectively.
