Search for Standard Model Higgs Boson Production in Association with Top Quark Pairs at CMS

After the discovery of a new boson of mass 125 GeV, one of the main goals of the LHC is to precisely measure its properties. Within the current experimental uncertainties, the properties of this boson are compatible with the expectation for the standard model (SM) Higgs boson. However, due to lack of sufficient data in Run-1, some of the properties of this particle are yet to be measured. The Yukawa coupling between this boson with the top (t) quark is one such crucially important property. Many beyond SM (BSM) theories predict deviations of this coupling from SM value as evidence for new physics. Higgs production in association with top quarks (ttH) allows a direct measurement of this coupling. In this talk, results of searches for ttH process are presented in final states involving bottom (b) quarks, photons, leptons and (hadronically decaying) tau leptons using Run-2 luminosity collected in 2016 (35.9 fb-1) at sqrt(s) = 13 TeV by the CMS experiment.
