The distribution of $m_{\ell \ell jj}$ in the $e\mathit{\mu }$ top-quark control region of the $H\to ZZ\to {\ell }^{+}{\ell }^{-}q\overline{q}$ search in the tagged ggF channel. The dashed line shows the total background used as input to the fit. The contribution labelled as ‘Top’ includes both the $t\overline{t}$ and single-top processes. The bottom pane shows the ratio of the observed data to the predicted background
