Abstract
Results of the search for the Higgs boson produced in association with either one top quark (tH) or a top quark pair (ttH) at the CMS experiment are presented. Dedicated searches of the Higgs decaying to a bb pair, multileptons (WW, ZZ, ττ) and a γγ pair are shown in this document. The analyzed data correspond to an integrated luminosity of 77.4 /fb recorded in proton-proton collisions at √s = 13 TeV center-of-mass energy in 2016 and 2017. The sensitivity of the searches is enhanced by using matrix element and machine learning methods to reconstruct the events and to separate the signals from the respective backgrounds. Standalone evidence of the targeted final states of the Standard Model (SM) ttH process has been found and interpretations of the tH process in beyond the SM scenarios are shown.
