The observed and expected 95% CL upper limits on the production cross section times branching fraction of a scalar particle are shown for the combination of the τ<sub>lep</sub>τ<sub>had</sub> and the τ<sub>had</sub>τ<sub>had</sub> channels. The production mechanism of H/A→ττ is assumed to be (a) gluon-gluon fusion or (b) b-associated production. For comparison, the expected limits for the individual channels, τ<sub>lep</sub>τ<sub>had</sub> and τ<sub>had</sub>τ<sub>had</sub>, are shown as well. The observed and expected 95% CL limits on tanβ as a function of m<sub>A</sub> are shown in (c) for the MSSM m<sub>h</sub><sup>mod+</sup> scenario and (d) for the hMSSM scenario. For comparison, the expected limits from the individual channels, τ<sub>lep</sub>τ<sub>had</sub> and τ<sub>had</sub>τ<sub>had</sub>, are given in (c), while the observed and expected limits from the ATLAS Run-1 analysis in Ref. [25] are shown in (d). Dashed lines of constant m<sub>h</sub> and m<sub>H</sub> values are shown in red and blue, respectively.
