We present the results of a search for particles which decay at a significant distance from their production point, using a final state containing charged hadrons and an associated muon. This analysis uses a data sample of proton-proton collisions at a center-of-mass energy of 7 TeV with an integrated luminosity of 4:4 fb−1 collected in 2011 by the ATLAS detector operating at the Large Hadron Collider. No signal events are observed and limits are set on the production cross-section as a function of the neutralino lifetime.
