| 英文摘要 | A measurement of the h -> tau tau 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 13tev. the data set corresponds to an integrated luminosity of 35.9 fb(-1). the h -> tau tau 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 -> tau tau signal production cross section and branching fraction is 1.09(-0.2)(6+0.27) 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 tau leptons by a single experiment.
