Search for Supersymmetry in final states with two hadronically decaying tau leptons at ATLAS

A search for the electroweak production of charginos and neutralinos in final states with at least two hadronically decaying tau leptons and MET is presented. The analysis uses a dataset of proton–proton collisions corresponding to an integrated luminosity of 36.1 fb^{1}, recorded with the ATLAS detector at the Large Hadron Collider at a centre-of-mass energy of 13 TeV. In additional, the prospect of the search for direct stau production at the High Luminosity LHC with ATLAS detector with 30000 fb^{-1} is performed.
