Abstract

This paper reports on a search for narrow reso-nances in diboson production in theq ̄qfinal state usingppcollision data corresponding to an integrated luminosityof 20 fb−1collected at√s=8 TeV with the ATLAS detec-tor at the Large Hadron Collider. No significant excess ofdata events over the Standard Model expectation is observed.Upper limits at the 95 % confidence level are set on the pro-duction cross section times branching ratio for Kaluza–Kleingravitons predicted by the Randall–Sundrum model and forExtended Gauge ModelW′bosons. These results lead to theexclusion of mass values below 740 and 1590 GeV for thegraviton andW′boson respectively.
