Abstract/Summary:
A search for Supersymmetry is presented. The search is done with final states containing jets, missing transverse energy and no leptons, using 4.7 fb-1 of proton-proton collision data at s = 7 TeV recorded by the ATLAS detector at the Large Hadron Collider. The analysis is carried out using new kinematic variables in two distinct signal regions with and without b-jet tagging. No significant excess above the Standard Model background expectation is observed, and limits are set on the Supersymmetry models. The results are interpreted as limits on the minimal supergravity framework, as well as a simplified Supersymmetry model of gluino pair-production.
