This paper reports on a search for narrow resonances in diboson production in the ℓℓqq̄ final state using pp collision data corresponding to an integrated luminosity of 20 fb−1 collected at √s = 8 TeV with the ATLAS detector at the Large Hadron Collider. No significant excess of data events over the StandardModel 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.

Abstract

This paper reports on a search for narrow resonances in diboson production in the ℓℓqq̄ final state using pp collision data corresponding to an integrated luminosity of 20 fb−1 collected at √s = 8 TeV with the ATLAS detector at the Large Hadron Collider. No significant excess of data events over the StandardModel 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.
