description A search for the Standard Model (SM) Higgs boson decaying into a pair of tau leptons is reported. The analysis, exploiting each of the tau-decay into leplep, lephad and hadhad final states, is based on data samples of proton-proton collisions collected by the ATLAS experiment at the LHC and corresponding to integrated luminosities of 4.6 fb-1 and 13.0 fb-1 at centre-ofmass energies of sqrt(s) = 7 TeV and 8 TeV, respectively. The observed (expected) upper limit at 95% CL on the cross-section times the branching ratio for SM H->tautau is found to be 1.9 (1.2) times the SM prediction for a Higgs boson with mass mH=125 GeV. For this mass, the observed (expected) deviation from the background-only hypothesis corresponds to a local significance of 1.1 (1.7) standard deviations.
