Following the observation of the Higgs boson at the LHC, the high precision measurements of its properties and the search for its production in various final states have become crucial to test the validity of the standard model.
The production of the Higgs boson in association with a top quark and antiquark pair (t$\bar{\text{t}}$H) is a direct probe of the interaction between the boson and the top quark, providing access to the top-Higgs Yukawa coupling. On the other hand, the production of the Higgs boson in association with a single top quark (tH) is sensitive to the sign of this coupling.
The importance of a precise measurement of the top Yukawa coupling stems from its dominant role in the stability of the electroweak vacuum, which motivates the study of processes involving the production of the Higgs boson in association with top quarks.
The latest results of measurements of the t$\bar{\text{t}}$H and tH associated production performed by the CMS collaboration with proton-proton collisions at $\sqrt{s}=$13 TeV in final states with a Higgs boson decaying to a pair of photons, multiple charged leptons or a bottom quark and antiquark pair are presented.
