Supersymmetric scenarios with a very weakly interacting lightest superparticle (LSP) - like the gravitino or axino - naturally give rise to a long-lived next-to-LSP (NLSP). In the case of a stau NLSP, the scenario shows up in a very prominent way at colliders. We present the LHC sensitivity for these classes of scenarios in the framework of simplified models. This allows for deriving robust limits on the masses of the lightest stau, the gluino and squarks.
