Measurement of the Higgs boson coupling to τ-leptons in proton-proton collisions at sqrt(s) = 13 TeV with the ATLAS detector at the LHC

The coupling of the Higgs boson to τ-leptons is one of the most precise measured coupling of the Higgs boson to fermions. Its coupling strength is measured using the decays of the Higgs boson into two τ-leptons in the gluon-fusion and vector boson fusion production channels. This poster presents results from the latest measurements of the Higgs boson coupling to τ-leptons by the ATLAS experiment using 36 fb −1 of proton-proton collision data at sqrt(s) = 13 TeV at the LHC. Machine-learning techniques have been applied in a measurement of CP properties.
