dc.description.abstract | A measurement of production cross sections of the Higgs boson in proton-proton collisions is presented in the H→ττ decay channel. The analysis is performed using 36.1 fb−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→ℓv¯v with ℓ=e, μ) and hadronic (τ→hadrons v) 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, for a Higgs boson of mass 125 GeV assuming the relative contributions of its production modes as predicted by the Standard Model. Total cross sections in the H→ττ decay channel are determined separately for vector-boson-fusion production and gluon-gluon-fusion production to be σ VBF H →ττ = 0.28 ± 0.09 (stat) + 0.11 − 0.09 (syst) pb and σ g g F H → ττ = 3.1 ± 1.0 (stat) + 1.6 − 1.3 (syst) pb, respectively. Similarly, results of a fit are reported in the framework of simplified template cross sections. All measurements are in agreement with Standard Model expectations. | en_US |
