First observation of the $\mathrm{t}\bar{\mathrm{t}}\mathrm{H}$ process at CMS

Abstract

The top quark and the Higgs boson play a special role in the fundamental interactions of the standard model. The observation of the top quark pair production in association with the Higgs boson establishes the first direct measurement of the tree-level coupling of the Higgs boson to the top quark. The analysis of the data collected by the CMS detector results in the overall observed significance of 5.2 standard deviations for this process.
