Abstract

This Letter reports on a search for narrow high-mass resonances decaying into dilepton final states. The data were recorded by the ATLAS experiment in pp collisions at √s=7TeV at the Large Hadron Collider and correspond to a total integrated luminosity of 1.08 (1.21)fb^-1 in the e ⁺e^- (μ⁺μ^-) channel. No statistically significant excess above the standard model expectation is observed and upper limits are set at the 95% C.L. on the cross section times branching fraction of Z^′ resonances and Randall-Sundrum gravitons decaying into dileptons as a function of the resonance mass. A lower mass limit of 1.83 TeV on the sequential standard model Z^′ boson is set. A Randall-Sundrum graviton with coupling k/M_̄Pl=0. 1 is excluded at 95% C.L. for masses below 1.63 TeV.
