The analysis is performed using 36.1fb−1 of data recorded by the ATLAS experiment at the Large Hadron Collider at a center-of-mass energy of s√=13 TeV. All combinations of leptonic (τ→lνν¯ with l=e, μ) and hadronic (τ→ hadrons ν) τ decays are considered. The H→ττ signal over the expected background from other Standard Model processes is established with an observed (expected) significance of 4.4 (4.1) standard deviations. Combined with results obtained using data taken at 7 and 8 TeV center-of-mass energies, the observed (expected) significance amounts to 6.4 (5.4) standard deviations and constitutes an observation of H→ττ decays. Using the data taken at s√=13 TeV, the total cross section in the H→ττ decay channel is measured to be 3.77+0.60−0.59(stat.)+0.87−0.74(syst.)pb.
