- This thesis presents studies on a new approach in the search for Supersymmetry (SUSY) using Simplified Models. While regular SUSY searches look for the signature of full SUSY models, Simplified Models exploit rare event topologies with exotic kinematics that can be part of many different SUSY scenarios. Once such a Simplified Model signature has been discovered, the construction of a full SUSY model around it is possible. This thesis starts out with the development of Simplified Models motivated by the physics accessible at LHC experiments like ATLAS with a special focus on final state tau leptons. As a primary model the strong production of squark pairs decaying via charginos and stau sleptons is studied. Furthermore, as auxilliary models, the direct electroweak pair production of charginos decaying into stau sleptons and the direct electroweak production of stau slepton pairs are studied. The two auxilliary models are developed to study and evaluate the influence of so-called hidden parameters of the primary model. For the model of chargino pair production as well as for the primary model exclusion limits on the model parameters or the model’s production cross sections are calculated. Finally the obtained results are interpreted in the context of the search for SUSY and proposals for future developments are discussed.
