Distributions of the BDT output used for the signal extraction in the $1\ell +2{\mathrm{\tau }}_{\mathrm{h}}$ (upper left), $4\ell +0{\mathrm{\tau }}_{\mathrm{h}}$ (upper right), $3\ell +1{\mathrm{\tau }}_{\mathrm{h}}$ (lower left), and $2\ell +2{\mathrm{\tau }}_{\mathrm{h}}$ (lower right) channels. The distributions expected for the $\mathrm{t}\overline{\mathrm{t}}\mathrm{H}$ and $\mathrm{t}\mathrm{H}$ signals and for background processes are shown for the values of the parameters of interest and of the nuisance parameters obtained from the ML fit. The best fit value of the $\mathrm{t}\overline{\mathrm{t}}\mathrm{H}$ and $\mathrm{t}\mathrm{H}$ production rates amounts to ${\widehat{\mu }}_{\mathrm{t}\overline{\mathrm{t}}\mathrm{H}}=0.92$ and ${\widehat{\mu }}_{\mathrm{t}\mathrm{H}}=5.7$ times the rates expected in the SM
