Search for heavy resonances in the dilepton channel

There are many extensions to the standard model of particle physics which predict the addition of a U(1) symmetry, and/or extra spatial dimensions, giving rise to new high mass resonances such as the Z' and Randall-Sundrum Graviton. The LHC provides a unique opportunity to explore the TeV scale where these phenomena may become apparent, and can be searched for using the precision tracking and high energy resolution calorimetry of the ATLAS Detector. This poster presents the search for high mass resonances in the dielectron and dimuon channel, as well as the combination of their results. This search was done with the ~ 1fb^-1 dataset from 2011 at a centre of mass energy of sqrt(s)=7TeV.
