Search for the associated production of the Higgs boson and a vector boson in proton-proton collisions at $$ \sqrt{s} $$ = 13 TeV via Higgs boson decays to τ leptons
A search for the standard model Higgs boson, decaying to a pair of $$\tau$$ leptons and produced in association with a W or a Z boson is performed. A data sample of proton-proton collisions collected at $$\sqrt{s} =$$ 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 $$\mu =$$ 2.5$$^{+1.4} _{-1.3}$$. These results are combined with earlier CMS measurements targeting Higgs boson decays to a pair of $$\tau$$ leptons, performed with the same data set in the gluon fusion and vector boson fusion production modes. The combined signal strength is $$\mu =$$ 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.
