Results of the Search for Strong Production of Supersymmetry involving Tau Leptons with the ATLAS Experiment — Philip Bechtle1, Klaus Desch1, •Oliver Ricken1, and Steffen Schaepe2 — 1Physikalisches Institut, Universität Bonn — 2CERN, Genf, Schweiz
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 the colliding protons, production of new particles via the strong interaction is favoured at the LHC. 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 searches for hadronic tau final states in different models of strong production of SUSY. The analysis presented is based on 36.1 fb−1 of ATLAS data recorded at √s=13 TeV. 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 analysis pursued and presents the latest results available, focussing on the novelties with respect to the first studies of 13 TeV ATLAS data.
