Fig. 9.

Distribution of three different kinematic discriminants versus $m_{4\ell }$: ${\mathcal{D}}_{\text{bkg}}^{\text{kin}}$ (upper), ${\mathcal{D}}_{\text{bkg}}^{\mathrm{VBF}+\text{dec}}$ (middle) and ${\mathcal{D}}_{\text{bkg}}^{{\mathrm{V}}_{}^{}\mathrm{H}+\text{dec}}$ (lower) shown in the mass region $105<m_{4\ell }<140\text{GeV}$. The blue scale represents the expected total number of $\mathrm{Z}\mathrm{Z}$, rare electroweak, and $\mathrm{Z}$+X background events. The red scale represents the number of expected SM H boson signal events for $m_{\mathrm{H}}=125\text{GeV}$. The points show the data from the categories listed in the legend
