The status of the search for the Standard Model (SM) Higgs decaying into a τ pair is reported. The analysis is based on the proton-proton data collected with the ATLAS detector corresponding to integrated luminosities of 4.6 fb−1 and
13.0 fb−1 at centre-of-mass energies of √s = 7TeV and 8TeV, respectively. The observed (expected) upper limit at 95% CL on the σ × BR for SM H → τ+τ− is found to be 1.9 (1.2) × SM prediction for mH = 125 GeV. For this Higgs mass the
observed (expected) deviation for the background only hypothesis corresponds to a local significance of 1.1 (1.7) standard deviations
