The first CMS search for the SM Higgs boson decaying into hadronic tau pairs in association with top-quark pairs is presented in this dissertation: with 19.4 /fb of √s=8TeV pp collision data collected by the CMS experiment, the expected and observed upper limits on the product of the cross section and branching ratio for the ttH→τhτh process are roughly 13 times the SM background expectation. cache/wp988g8752p.txt txt/wp988g8752p.txt
