CERN-LHC. Study of events which have a disappearing track signature, characteristic of the decay of a nearly degenerate lightest chargino, produced in proton-proton collisions at a centre-of-mass energy of 7 TeV. The data sample, collected from March to July 2011 has a total integrated luminosity of 1.02 fb-1. Events are selected at the trigger levels by requiring at least one jet, constructed using the anti-kT algorithm, with PT above 75 GeV and missing PT above 55 GeV. The data is interpreted in the minimal AMSB framework.
