Measurement of Higgs boson production in the decay channel with a pair of $\tau$ leptons

Measurements of Higgs boson production in the channel where the Higgs boson decays to $\tau$ leptons are performed. The analysis uses events recorded in proton-proton collisions by the CMS experiment at the CERN LHC in 2016, 2017, and 2018 at a center-of-mass energy of $13~\mathrm{TeV}$. The data sets correspond to a total integrated luminosity of $137~\mathrm{fb}^{-1}$. The product of the $\mathrm{H}\rightarrow\tau \tau$ signal production cross section and branching fraction is measured to be $0.85^{+0.12}_{-0.11}$ times the standard model expectation. This analysis targets primarily the gluon fusion and the vector boson fusion production modes. Measurements of the signal strengths and products of the cross section and branching fraction are also performed in the simplified template cross section scheme, providing precise measurements of the Higgs boson production at high transverse momentum and in event topologies with jets. $$\textit{This document has been revised with respect to the version dated July 31, 2020.}$
