Search for high-mass dilepton resonances with 5 fb$^{-1}$ of $pp$ collisions at $\sqrt{s}=7$ TeV

This poster describes the search for high-mass $ee$ and $\mu\mu$ resonances in $pp$ collisions at $\sqrt{s}=7$ TeV with the ATLAS experiment, with a data set corresponding to a total integrated luminosity of 5 fb$^{-1}$. No significant excess above the Standard Model expectation has been observed. Therefore, upper limits at the 95\% C.L. were set on the cross-section times branching ratio of various $Z'$ resonances and Randall-Sundrum gravitons ($G^*$) decaying into dileptons as a function of the resonance mass. It is entirely based on the 2012 Moriond conference note, ATLAS-CONF-2012-007.
