The first observation of the $t\overline{t}H$ process in a single Higgs boson decay channel with the full reconstruction of the final state ($H\ensuremath{\rightarrow}\ensuremath{\gamma}\ensuremath{\gamma}$) is presented, with a significance of 6.6 standard deviations ($\ensuremath{\sigma}$). The $CP$ structure of Higgs boson couplings to fermions …
