Distribution of kinematic discriminants in the mass region $118<m_{4\ell }<130\text{GeV}$: (uppper) ${\mathcal{D}}_{\text{bkg}}^{\text{kin}}$ , (center) ${\mathcal{D}}_{\text{bkg}}^{\mathrm{VBF}+\text{dec}}$, (lower) ${\mathcal{D}}_{\text{bkg}}^{{\mathrm{V}}_{}^{}\mathrm{H}+\text{dec}}$. Points with error bars represent the data and stacked histograms represent expected distributions of the signal and background processes. The yields of the different H boson production mechanisms with $m_{\mathrm{H}}=125\text{GeV}$, denoted as $\mathrm{H}(125)$, and those of the $\mathrm{Z}\mathrm{Z}$ and rare electroweak backgrounds are normalized to the SM expectations, while the $\mathrm{Z}$+X background yield is normalized to the estimate from the data. In the center and lower figures 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
