A search for supersymmetric particles in final states with zero, one, and two leptons, with and without jets identified as originating from b -quarks, in 4.7 fb − 1 of √ s = 7TeV pp collisions produced by the Large Hadron Collider and recorded by the ATLAS detector is presented. The search uses a set of variables carrying information on the event kinematics transverse and parallel to the beam line that are sensitive to several topologies expected in super- symmetry. Mutually exclusive final states are defined, al- lowing a combination of all channels to increase the search sensitivity. No deviation from the Standard Model expecta- tion is observed. Upper limits at 95 % confidence level on visible cross-sections for the production of new particles are extracted. Results are interpreted in the context of the con- strained minimal supersymmetric extension to the Standard Model and in supersymmetry-inspired models with diverse, high-multiplicity final states.
