Abstract
A search for the standard model Higgs boson produced in association with a W or a Z boson and decaying to a pair of τ leptons is performed. A data sample of proton-proton collisions collected at √s = 13 TeV by the CMS experiment at the CERN
LHC is used, corresponding to an integrated luminosity of 35.9 fb−1. The signal strength
is measured relative to the expectation for the standard model Higgs boson, yielding µ =
2.5+1.4−1.3. These results are combined with earlier CMS measurements targeting Higgs boson
decays to a pair of τ leptons, performed with the same data set in the gluon fusion and vector boson fusion production modes. The combined signal strength is µ = 1.24+0.29−0.27(1.00+0.24−0.23 expected), and the observed significance is 5.5 standard deviations (4.8 expected) for a Higgs boson mass of 125 GeV.
