Abstract

<jats:title>A<jats:sc>bstract</jats:sc> </jats:title> <jats:p>A search for the standard model Higgs boson produced in association with a W or a Z boson and decaying to a pair of <jats:italic>τ</jats:italic> leptons is performed. A data sample of proton-proton collisions collected at <jats:inline-formula> <jats:alternatives> <jats:tex-math>$$ \sqrt{s} $$</jats:tex-math> <mml:math xmlns:mml="http://www.w3.org/1998/Math/MathML"> <mml:msqrt> <mml:mi>s</mml:mi> </mml:msqrt> </mml:math> </jats:alternatives> </jats:inline-formula> = 13 TeV by the CMS experiment at the CERN LHC is used, corresponding to an integrated luminosity of 35.9 fb<jats:sup>−1</jats:sup>. The signal strength is measured relative to the expectation for the standard model Higgs boson, yielding <jats:italic>μ</jats:italic> = 2.5 <jats:sub>− 1.3</jats:sub> <jats:sup>+ 1.4</jats:sup> . These results are combined with earlier CMS measurements targeting Higgs boson decays to a pair of <jats:italic>τ</jats:italic> leptons, performed with the same data set in the gluon fusion and vector boson fusion production modes. The combined signal strength is <jats:italic>μ</jats:italic> = 1.24 <jats:sub>− 0.27</jats:sub> <jats:sup>+ 0.29</jats:sup> (1.00 <jats:sub>− 0.23</jats:sub> <jats:sup>+ 0.24</jats:sup> expected), and the observed significance is 5.5 standard deviations (4.8 expected) for a Higgs boson mass of 125 GeV. </jats:p>
