note = {Discovery prospects for Supersymmetry in final states with at least two tau leptons and large missing transverse energy are evaluated for LHC proton-proton collisions measured with the ATLAS detector. In a first study based on Monte Carlo simulation, a Supersymmetry signal selection is developed for fully hadronic, semileptonic and fully leptonic di-tau decays in events produced in proton-proton collisions with a center-of-mass energy of √s=10 TeV. The prospects of measuring the kinematic endpoint of the di-tau invariant mass distribution assuming an integrated luminosity of ∫ L dt=1 fb−1 are evaluated for different mSUGRA scenarios along with the discovery reach. In a second study, a search for Supersymmetry in the fully hadronic channel is performed, using ∫ L dt=35 pb−1 of ATLAS data collected with proton-proton collisions at √s=7 TeV between June 24th and October 29th 2010. Two events are observed, which is consistent with the Standard Model background expectation of NSM = 0.77 ± 0.19(stat)-0.33+0.55 (syst). Interpreted in mSUGRA, limits on m0 and m1/2 are set for tan ß=40, a positive higgsino mixing parameter and A0 =0 GeV or A0 =-500 GeV. These limits constitute the first results of SUSY searches with tau leptons within the ATLAS experiment.},
