This process depends directly on the the top quark Yukawa coupling and provides access to its properties. In particular, a CP-odd component is allowed in models beyond the Standard Model with extended Higgs sectors. Studies of the feasibility of such a measurement at the 13 TeV LHC were carried out, in the $H\\rightarrow b\\bar b$ decay channel and with the $t\\bar t$ system decaying through the semileptonic and dileptonic channels.
