Observation of the higgs boson decay to a pair of τ leptons with the CMS detector
A measurement of the H → ττ signal strength is performed using events recorded in proton–proton collisions by the CMS experiment at the LHC in 2016 at a center-of-mass energy of 13 TeV. The data set corresponds to an integrated luminosity of 35.9 fb−1. The H → ττ signal is established with a sign...

| description | A measurement of the H → ττ signal strength is performed using events recorded in proton–proton
collisions by the CMS experiment at the LHC in 2016 at a center-of-mass energy of 13 TeV. The
data set corresponds to an integrated luminosity of 35.9 fb−1. The H → ττ signal is established
with a significance of 4.9 standard deviations, to be compared to an expected significance of 4.7
standard deviations. The best fit of the product of the observed H → ττ signal production cross section
and branching fraction is 1.09+0.27
−0.26 times the standard model expectation. The combination with the
corresponding measurement performed with data collected by the CMS experiment at center-of-mass
energies of 7 and 8 TeV leads to an observed significance of 5.9 standard deviations, equal to the expected
significance. This is the first observation of Higgs boson decays to τ leptons by a single experiment. |
