Two-dimensional exclusion regions as a function of the ($\kappa _{\lambda }$, $\kappa _{2V}$) and ($\kappa _{V}$, $\kappa _{2V}$) are shown in their Figs. 13 and 14.

The vector boson decays both leptonically (${{\mathit W}}$ $\rightarrow$ ${{\mathit \ell}}{{\mathit \nu}}$, ${{\mathit Z}}$ $\rightarrow$ ${{\mathit \ell}}{{\mathit \ell}}$, ${{\mathit \nu}}{{\mathit \nu}}$, ${{\mathit \ell}}$ = ${{\mathit e}}$ , ${{\mathit \mu}}$) and hadronically. All other Higgs couplings are fixed to the SM values. Two-dimensional exclusion regions as a function of the $\kappa _{2V}$ and $\kappa _{\lambda }$ parameters are shown in their Fig. 14, with other couplings fixed to the SM values. The best fit value is ($\kappa _{\lambda }$, $\kappa _{2V}$) = (-2.6, 10.1). The constraints on $\kappa _{2W}$ and $\kappa _{2Z}$ are separately measured to be -14.0 $<$ $\kappa _{2W}$ $<$ 15.4 and -17.4 $<$ $\kappa _{2Z}$ $<$ 18.5 (95$\%$ CL). The quoted $\kappa _{2V}$ (${{\mathit V}}$ = ${{\mathit W}}$ , ${{\mathit Z}}$) is measured assuming all other Higgs boson couplings are at their SM value. See their Table 7.

The vector boson decays leptonically (${{\mathit W}}$ $\rightarrow$ ${{\mathit \ell}}{{\mathit \nu}}$, ${{\mathit Z}}$ $\rightarrow$ ${{\mathit \ell}}{{\mathit \ell}}$, ${{\mathit \nu}}{{\mathit \nu}}$, ${{\mathit \ell}}$ = ${{\mathit e}}$ , ${{\mathit \mu}}$). The constraints on $\kappa _{2W}$ and $\kappa _{2Z}$ are separately measured to be -12.3 $<$ $\kappa _{2W}$ $<$ 13.5 and -9.9 $<$ $\kappa _{2Z}$ $<$ 11.3 (95$\%$ CL). The quoted $\kappa _{2V}$ (${{\mathit V}}$ = ${{\mathit W}}$ , ${{\mathit Z}}$) is measured assuming all other Higgs boson couplings are at their SM value.
11  AAD 2023AT combine results from $126 - 139$ fb${}^{-1}$ of data at $\mathit E_{{\mathrm {cm}}}$ = 13 TeV for ${{\mathit p}}$ ${{\mathit p}}$ $\rightarrow$ ${{\mathit H}}{{\mathit H}}$ $\rightarrow$ ${{\mathit b}}{{\overline{\mathit b}}}{{\mathit b}}{{\overline{\mathit b}}}$ (AAD 2023BK), ${{\mathit b}}{{\overline{\mathit b}}}{{\mathit \tau}}{{\mathit \tau}}$ (AAD 2023Z), and ${{\mathit b}}{{\overline{\mathit b}}}{{\mathit \gamma}}{{\mathit \gamma}}$ (AAD 2022Y). The quoted values are obtained from the 95$\%$ CL VBF ${{\mathit H}}{{\mathit H}}$ cross-section upper limit as a function of $\kappa _{2V}$ as shown in their Fig. 4(b). All other coupling modifiers are assumed to have their SM values.
12  AAD 2023BK search for non-resonant ${{\mathit H}}{{\mathit H}}$ production using ${{\mathit H}}$ ${{\mathit H}}$ $\rightarrow$ ${{\mathit b}}{{\overline{\mathit b}}}{{\mathit b}}{{\overline{\mathit b}}}$ with data of 126 fb${}^{-1}$ at $\mathit E_{{\mathrm {cm}}}$ = 13 TeV. The quoted values are obtained from the one-dimensional profile likelihood scan as a function of $\kappa _{2V}$. See their Fig. 12 (b). The $\mu _{VBF}$ measurement for different values of $\kappa _{2V}$ constrains -0.03 $<$ $\kappa _{2V}$ $<$ 2.11 at 95$\%$ CL as shown in their Fig. 10 (b). $\kappa _{\lambda }$= $\kappa _{V}$ = 1 is assumed in both cases.

The $\kappa _{2V}$ = 0 is excluded at 6.3 $\sigma $ assuming all other Higgs boson couplings are at their SM values.
14  TUMASYAN 2023D search for non-resonant ${{\mathit H}}{{\mathit H}}$ production using ${{\mathit H}}$ ${{\mathit H}}$ $\rightarrow$ ${{\mathit b}}{{\overline{\mathit b}}}{{\mathit \tau}}{{\mathit \tau}}$ with data of 138 fb${}^{-1}$ at $\mathit E_{{\mathrm {cm}}}$ = 13 TeV. The quoted values are obtained from the upper limits on the ${{\mathit H}}{{\mathit H}}$ production cross section times the ${{\mathit b}}{{\overline{\mathit b}}}{{\mathit \tau}}{{\mathit \tau}}$ branching fraction for different values of $\kappa _{2V}$. See their Fig. 8 (right). All other coupling modifiers are assumed to be 1. In addition, two-dimensional exclusion regions as a function of the $\kappa _{2V}$ and $\kappa _{V}$ couplings, with $\kappa _{\lambda }$ = $\kappa _{t}$ = 1, are shown in their Fig. 9 (right). The one-dimensional likelihood scan as a function of $\kappa _{2V}$ is given in their Fig. 10 (right), from which a 95$\%$ confidence interval of -0.34 $<$ $\kappa _{2V}$ $<$ 2.49 is extracted.
