The Search for the Higgs Boson Produced in Association with a Top Quark Pair
With the recent observation at ATLAS and CMS of a new particle, consistent with the Standard Model Higgs, with a mass near 125.7 GeV, the focus of the Higgs search has turned to testing whether the properties of this new particle are consistent with Standard Model expectations.
A critical element of this test is verifying that this new particle couples with the expected strengths to the known bosons and fermions, especially the top quark. Higgs production in association with a top quark pair is a direct probe of this coupling. However, the analysis must overcome challenging backgrounds, in particular, involving top pair production. In this talk, I will present the status of the search for Higgs produced in association with top quarks at the CMS experiment.
