Abstract

A search for the standard model Higgs boson produced in association with a top-quark pair (ttH) is presented, using data samples corresponding to integrated lumi- nosities of up to 5.1 fb−1 and 19.7 fb−1 collected in pp collisions at center-of-mass energies of 7 TeV and 8 TeV respectively. The search is based on the following signatures of the Higgs boson decay: H → hadrons, H → photons, and H → leptons. The results are char- acterized by an observed ttH signal strength relative to the standard model cross section, µ = σ/σSM, under the assumption that the Higgs boson decays as expected in the standard model. The best fit value is µ = 2.8 ± 1.0 for a Higgs boson mass of 125.6 GeV.
