Search for New Physics in Hadronic Final States with Missing Transverse Energy and Heavy Flavor

Results are presented of a search for new physics in events with large missing transverse energy and heavy flavor jet candidates in 7 TeV proton-proton collisions recorded by the ATLAS experiment at the Large Hadron Collider in 2011. Events are required to contain energetic jets, of which one or two must be identified as a b-jet, large missing transverse energy and no isolated leptons (electron or muon). The results are interpreted in the context of phenomenological MSSM/simplified models.
