dc.description.abstractMeasurements 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 +/- 0.11 for inclusive Higgs boson production, 0.67 +/- 0.19 (0.81 +/- 0.17) for the production mainly via gluon fusion (vector boson fusion), and 1.79 +/- 0.45 for vector boson associated Higgs boson production.en_US
