Discovering supersymmetry with m02<0 in the first CERN LHC physics run

In minimal supergravity, the parameter space where the slepton is the lightest superpartner is usually neglected, because of strong constraints on charged dark matter. When the gravitino is the true lightest superpartner, this region avoids these constraints and offers spectacular collider signals. We investigate this scenario for the Large Hadron Collider and find that a large portion of the ignored minimal supergravity parameter space can lead to discovery within the first physics run, with 1-4 fb(-1) of data. We find that there are regions where discovery is feasible with only 1 d of running.
