  • A bstractA search for the standard model Higgs boson produced in association with a top-quark pair tt¯H$$ \left(\mathrm{t}\overline{\mathrm{t}}\mathrm{H}\right) $$ is presented, using data samples corresponding to integrated luminosities 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… CONTINUE READING
