Distributions for one-lepton SUSY Searches with the ATLAS Detector

Using the 7 TeV proton-proton collisions at the LHC, distributions of relevant supersymmetry-sensitive variables will be shown for the final state containing jets, missing transverse momentum and 1 lepton. With increased integrated luminosities, selections based on these distributions will be used in the search for supersymmetric particles: it is thus important to show that the Standard Model backgrounds to these searches are under good control.
