| Abstract: Measurements of Higgs boson production, where the Higgs boson decays into a pair of $ \tau $ leptons, are presented, using a sample of proton-proton collisions collected with the CMS experiment at a center-of-mass energy of 13 TeV, corresponding to an integrated luminosity of 138 fb$^{-1}$. Three analyses are presented. Two are targeting Higgs boson production via gluon fusion and vector boson fusion: a neural network based analysis and an analysis based on an event categorization optimized on the ratio of signal over background events. These are complemented by an analysis targeting vector boson associated Higgs boson production. Results are presented in the form of signal strengths relative to the standard model predictions and products of cross sections and branching fraction to $ \tau $ leptons, in up to 16 different kinematic regions. For the simultaneous measurements of the neural network based analysis and the analysis targeting vector boson associated Higgs boson production signal strengths are found to be 0.82 $ \pm $ 0.11 for inclusive Higgs boson production, 0.67 $ \pm $ 0.19 (0.81 $ \pm $ 0.17) for the production mainly via gluon fusion (vector boson fusion), and 1.79 $ \pm $ 0.45 for vector boson associated Higgs boson production. | ||

| Summary |
| Measurements of Higgs boson production, where the Higgs boson decays into a pair of $ \tau $ leptons, have been presented. The analyzed data are selected from proton-proton collisions at a center-of-mass energy of 13 TeV collected by the CMS experiment at the LHC from 2016--2018, corresponding to an integrated luminosity of 138 fb$^{-1}$. Results are presented in the form of signal strengths relative to the standard model predictions and products of cross sections and branching fraction to $ \tau $ leptons, in up to 16 different kinematic regions, following the simplified template cross section scheme of the LHC Higgs Working Group. For the simultaneous measurements of a neural network based analysis and an analysis targeting vector boson associated Higgs boson production signal strengths are found to be 0.82 $ \pm $ 0.11 for inclusive Higgs boson production, 0.67 $ \pm $ 0.19 (0.81 $ \pm $ 0.17) for the production mainly via gluon fusion (vector boson fusion), and 1.79 $ \pm $ 0.45 for vector boson associated Higgs boson production. The latter result significantly improves an earlier measurement performed by the CMS Collaboration on a smaller data set. |
