|a This Letter presents a search for contact interactions in the dielectron and dimuon channels using data from proton-proton collisions produced by the LHC at √s = 7 TeV and recorded by the ATLAS detector. The data sample, collected in 2011, corresponds to an integrated luminosity of 1.08 and 1.21 fb[superscript −1] in the e[superscript +]e[superscript −] and μ[superscript +]μ[superscript −] channels, respectively. No significant deviations from the standard model are observed. Using a Bayesian approach with a prior flat in [1 over Λ[superscript 2]], the following 95% CL lower limits are placed on the energy scale of ℓℓqq contact interactions: Λ[superscript −]>10.1 TeV(Λ[superscript +]>9.4 TeV) in the electron channel and Λ[superscript −]>8.0 TeV (Λ[superscript +]>7.0 TeV) in the muon channel for constructive (destructive) interference in the left-left isoscalar contact interaction model. Limits are also provided for a prior flat in [1 over Λ[superscript 4]].
