Search for supersymmetry in pp collisions at √s=7 TeV in final states with missing transverse momentum and b-jets

Results are presented of a search for supersymmetric particles in events with large missing transverse momentum and at least one heavy flavour jet candidate in √s=7 TeV proton-proton collisions. In a data sample corresponding to an integrated luminosity of 35 pb -1 recorded by the ATLAS experiment a...
