Search for high-mass dilepton resonances with the ATLAS experiment at √s = 7 TeV

This poster describes the search for high-mass e+e- and mu+mu- resonances in pp collisions at √s = 7 TeV with the ATLAS experiment, with a data set corresponding to a total integrated luminosity of 1.21 fb-1. No statistically significant excess above the Standard Model processes is observed, so upper limits at the 95% confidence level are set on the cross-section times branching ratio of Z' resonances and Randall-Sundrum gravitons decaying into dileptons as a function of the resonance mass.
