Latest developments in the search for supersymmetry with tau leptons at the ATLAS experiment

The upgraded Large Hadron Collider (LHC) and ATLAS experiment provide a new and unique discovery potential for physics beyond the Standardmodel (SM). One of the most promising extensions to the successful yet incomplete SM is Supersymmetry (SUSY). While in proton-proton collisions production through the strong interaction is favoured, it is due to the nature of SUSY itself that tau leptons and their distinct detector signatures are expected to be rather abundant. These two aspects make up the foundation and motivation of this new physics search. This talk addresses the ongoing searches for hadronic di-tau final states in different models of SUSY as pursued by the ATLAS collaboration. In contrast to the Run-I analyses this study focuses on Simplified Models (SMS) of SUSY. After introducing the SMS searched for, the analysis strategy and design are presented. Finally, the expected sensitivity in this first 13 TeV analysis is shown and discussed.
