This Letter presents the first search for supersymmetry in final states containing one isolated electron or muon, jets, and missing transverse momentum from sqrt{s} = 7 TeV proton-proton collisions at the LHC. The data were recorded by the ATLAS experiment during 2010 and correspond to a total integrated luminosity of 35 pb-1. No excess above the standard model background expectation is observed. Limits are set on the parameters of the minimal supergravity framework, extending previous limits. For A_0 = 0 GeV, tan beta = 3, mu > 0 and for equal squark and gluino masses, gluino masses below 700 GeV are excluded at 95% confidence level.

Combined exclusion reach of searches for squarks and gluinos using final states with jets, missing transverse momentum, and zero or one lepton, with the ATLAS detector in sqrt(s)=7 TeV proton-proton collisions

The combination of searches for squarks and gluinos in final states containing jets, missing transverse momentum and zero or one electron or muon is presented. In the MSUGRA/CMSSM framework with tan beta=3, A_0=0 and mu>0, squarks and gluinos of equal mass are excluded below 815 GeV. These are the most stringent limits to date.
