- Abstract
- Abstract Measurements of the production cross-sections of the Standard Model (SM) Higgs boson (H) decaying into a pair of τ-leptons are presented. The measurements use data collected with the ATLAS detector from pp collisions produced at the Large Hadron Collider at a centre-of-mass energy of s $ \sqrt{s} $ = 13 TeV, corresponding to an integrated luminosity of 139 fb−1. Leptonic (τ → ℓνℓντ) and hadronic (τ → hadrons ντ) decays of the τ-lepton are considered. All measurements account for the branching ratio of H → ττ and are performed with a requirement |yH| < 2.5, where yH is the true Higgs boson rapidity. The cross-section of the pp → H → ττ process is measured to be 2.94 ± 0.21 stat − 0.32 +0.37$ 0.21{\left(\mathrm{stat}\right)}_{-0.32}^{+0.37} $ (syst) pb, in agreement with the SM prediction of 3.17 ± 0.09 pb. Inclusive cross-sections are determined separately for the four dominant production modes: 2.65 ± 0.41 stat − 0.67 + 0.91$ 0.41{\left(\mathrm{stat}\right)}_{-0.67}^{+0.91} $ (syst) pb for gluon-gluon fusion, 0.197 ± 0.028 stat − 0.026 + 0.032 $ 0.028{\left(\mathrm{stat}\right)}_{-0.026}^{+0.032} $ (syst) pb for vector-boson fusion, 0.115 ± 0.058 stat − 0.040 + 0.042 $ 0.058{\left(\mathrm{stat}\right)}_{-0.040}^{+0.042} $ (syst) pb for vector-boson associated production, and 0.033 ± 0.031 stat − 0.017 + 0.022 $ 0.031{\left(\mathrm{stat}\right)}_{-0.017}^{+0.022} $ (syst) pb for top-quark pair associated production. Measurements in exclusive regions of the phase space, using the simplified template cross-section framework, are also performed. All results are in agreement with the SM predictions.
