Search for Higgs Boson Decaying to Tau Lepton Pairs in pp Collisions with the CMS Detector

Measurement of the H → τ τ signal strength is performed using events recorded in p-p 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 → τ τ 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 → τ τ 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. There are many decay channels, but the more prominent channels are mentioned and discussed in detail.
