: $\mFourL$ per lepton flavour channel

Differential cross-sections as a function of the four-lepton invariant mass $\mFourL$ predicted by MC simulation. The total $gg\rightarrow 4\ell$ includes contributions from $gg\rightarrow H^{(\ast)} \rightarrow 4\ell$ as well as $gg \rightarrow 4\ell$ and the interference between the two. The $\qqZZ$ and $\ggZZ$ processes including off-shell Higgs boson production are modelled using $\SHERPAV{2.2.2}$ including all corrections described in Section~\ref{sec:MC}, while on-shell Higgs production is modelled using the dedicated samples based on $\POWHEG+\PYTHIAV{8}$ and \MGMCatNLO + \HERWIGpp described in the same section.

: double-differential $|\yFourL|$-$\mFourL$

:

Distribution of events passing the selection as a function of the four-lepton invariant mass $\mFourL$ and of $|\yFourL|$, where observed event yields (black dots) are compared with the total SM prediction. The $\mFourL$ bins are shown along the horizontal axis, and the bins of $|\yFourL|$ are stacked vertically and labelled with the bin range values. The ratio of the data to the prediction as a function of $\mFourL$ for each secondary variable bin is given in the panel to the right-hand side. The statistical uncertainty of the data is displayed with black error bars and the total uncertainty (including statistical and systematic sources) of the prediction is displayed with a grey hashed band.

Observed (solid) and expected (dashed) exclusion limits at $95\%$ CL in the $c_{g}$ versus $c_{t}$ plane for modified $t\bar{t}H$ and $ggH$ couplings. The uncertainties in the expected limit corresponding to one and two standard deviations are displayed as green and yellow bands respectively. The hollow circle denotes the tree-level SM values of the parameters: $c_{g}=0$ and $c_{t}=1$.

Measured differential cross-section (black dots) compared with particle-level SM predictions (coloured lines) as a function of $\mFourL$ in slices of $|\yFourL|$. The total systematic plus statistical uncertainty of the measured cross-section is displayed as a grey band. Two SM predictions with different event generator samples for $\qqZZ$ (described in Section~\ref{sec:MC}) are shown with different line colours and styles. In addition, an unmodified NNLO-precision fixed-order calculation using the MATRIX program is shown with a grey histogram, to illustrate the effects of additional higher-order corrections and QED final state radiation included in the event generator predictions.The $\mFourL$ bins are given along the horizontal axis, and the bins of the secondary variable are stacked vertically and labelled with the bin range values. The ratio of the particle-level MC predictions to the unfolded data as a function of $\mFourL$ for each secondary variable bin is given in the panel to the right-hand side.
