Latest Developments in the Search for Supersymmetry with Tau Leptons at the ATLAS Experiment — Philip Bechtle, Florian Beisiegel, Klaus Desch, Philipp König, •Oliver Ricken, and Steffen Schaepe — Physikalisches Institut, Universität Bonn

The reliably running Large Hadron Collider (LHC) and the ATLAS experiment provide a new and unique discovery potential for physics beyond the Standard Model (SM). One of the most promising extensions to the successful yet incomplete SM is Supersymmetry (SUSY).
Due to the quark-gluon composition of protons, particle-particle collisions of the latter favour production of new particles via the strong interaction. This fact motivates searches for strongly produced decay chains of SUSY. In addition, it is natural in models of SUSY that tau leptons and their distinct detector signatures are expected to be rather abundant.
This talk addresses the ongoing searches for hadronic tau final states in different models of strong production of SUSY. The analyses presented are based on the full 13 TeV ATLAS dataset. In contrast to the early Run-II analyses, this study exploits the increased amount of data available in various ways: in addition to improved background estimation approaches, new fitting procedures are utilised to extract results more efficiently.
This talk introduces the analyses pursued and presents the latest results available, focussing on the novelties with respect to the first studies of 2015 ATLAS data.
