Search for $t\bar{t}H$ production at the LHC

The searches for the production of the Higgs boson associated with a pair of top quarks in the ATLAS and CMS experiments are presented. The searches use a range of final states sensitive to the Higgs boson decaying into b-quark pairs, pairs of vector bosons, pairs of taus and pairs of photons. All t...

description The searches for the production of the Higgs boson associated with a pair of top quarks in the ATLAS and CMS experiments are presented. The searches use a range of final states sensitive to the Higgs boson decaying into b-quark pairs, pairs of vector bosons, pairs of taus and pairs of photons. All the searches use pp collision data at sqrt(s) = 8 TeV collected with the ATLAS and CMS detectors at the LHC in 2012 and some analyses also include the data collected at sqrt(s) = 7 TeV in 2011. The searches in the bbbar and gammagamma channels observe no excess of events relative to the background expectation, while the CMS search using multi-lepton events observes an excess of slightly more than 3 standard deviations over the background expectation.
