Distribution of categorization discriminants in the mass region $118<m_{4\ell }<130\text{GeV}$: ${\mathcal{D}}_{\text{2jet}}^{\mathrm{VBF}}$ (upper), ${\mathcal{D}}_{\text{1jet}}^{\mathrm{VBF}}$ (center), ${\mathcal{D}}_{\text{2jet}}^{{\mathrm{V}}_{}^{}\mathrm{H}}$ (lower) = max(${\mathcal{D}}_{\text{2jet}}^{\mathrm{W}\mathrm{H}}$,${\mathcal{D}}_{\text{2jet}}^{\mathrm{Z}\mathrm{H}}$). Points with error bars represent the data and stacked histograms represent expected distributions of the signal and background processes. The SM Higgs boson signal with $m_{\mathrm{H}}=125\text{GeV}$, denoted as $\mathrm{H}(125)$, and the $\mathrm{Z}\mathrm{Z}$ backgrounds and rare electroweak backgrounds are normalized to the SM expectation, the $\mathrm{Z}$+X background to the estimation from data. The vertical dashed lines denote the working points used in the event categorization. The SM H boson signal is separated into two components: the production mode which is targeted by the specific discriminant, and other production modes, where the gluon fusion process dominates.
