Production rate ${\widehat{\mu }}_{\mathrm{t}\overline{\mathrm{t}}\mathrm{H}}$ of the $\mathrm{t}\overline{\mathrm{t}}\mathrm{H}$ signal (left) and ${\widehat{\mu }}_{\mathrm{t}\mathrm{H}}$ of $\mathrm{t}\mathrm{H}$ signal (right), in units of their rate of production expected in the SM, measured in each of the ten channels individually and for the combination of all channels. The central value of the signal strength in the $2\ell +2{\mathrm{\tau }}_{\mathrm{h}}$is constrained to be greater than zero
