| Copyright/License | publication: © Pleiades Publishing, Ltd. 2021 The search for the associated production of a Higgs boson with a top quark–antiquark pair with the CMS detector will be presented. Candidate $t\bar{t}H$ events are selected with criteria enhancing respectively the dileptonic, semileptonic and fully hadronic decay channels of the $t\bar{t}$ system and the decay of the Higgs boson into a bottom quark–antiquark pair ($H\rightarrow b\bar{b}$). In order to increase the sensitivity of the search, selected events are split into several categories with different expected signal and background rates. A combined fit of multivariate discriminant templates across all categories and decay channels is performed to extract the result. Results for Run II data will be shown. Prospects for improvements towards Run III will also be discussed. |
