1  AAD 2023AD search for non-resonant ${{\mathit H}}{{\mathit H}}$ production in association with a vector boson using ${{\mathit H}}$ ${{\mathit H}}$ $\rightarrow$ ${{\mathit b}}{{\overline{\mathit b}}}{{\mathit b}}{{\overline{\mathit b}}}$ with data of 139 fb${}^{-1}$ at $\mathit E_{{\mathrm {cm}}}$ = 13 TeV. 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.
2  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.
3  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.
4  TUMASYAN 2023AE search for ${{\mathit H}}{{\mathit H}}$ production using ${{\mathit H}}$ ${{\mathit H}}$ $\rightarrow$ ${{\mathit b}}{{\overline{\mathit b}}}{{\mathit b}}{{\overline{\mathit b}}}$, where both ${{\mathit b}}{{\overline{\mathit b}}}$ pairs are highly boosted, with data of 138 fb${}^{-1}$ at $\mathit E_{{\mathrm {cm}}}$ = 13 TeV. The $\kappa _{2V}$ = 0 is excluded at 6.3 $\sigma $ assuming all other Higgs boson couplings are at their SM values.
5  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.
6  CMS 2022 report combined results (see their Extended Data Table 2) using 138 fb${}^{-1}$ of data at $\mathit E_{{\mathrm {cm}}}$ = 13 TeV. See their Fig. 6 (right).
7  TUMASYAN 2022AN 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 138 fb${}^{-1}$ at $\mathit E_{{\mathrm {cm}}}$ = 13 TeV. The upper limit on the ${{\mathit p}}$ ${{\mathit p}}$ $\rightarrow$ ${{\mathit H}}{{\mathit H}}$ production cross section at 95$\%$ CL is shown as a function of $\kappa _{2V}$ in their Fig. 2 (bottom).
8  SIRUNYAN 2021K search for non-resonant ${{\mathit H}}{{\mathit H}}$ production using ${{\mathit H}}$ ${{\mathit H}}$ $\rightarrow$ ${{\mathit \gamma}}{{\mathit \gamma}}{{\mathit b}}{{\overline{\mathit b}}}$ with data of 137 fb${}^{-1}$ at $\mathit E_{{\mathrm {cm}}}$ = 13 TeV.
9  AAD 2020X search for ${{\mathit H}}$ ${{\mathit H}}$ $\rightarrow$ ${{\mathit b}}{{\overline{\mathit b}}}{{\mathit b}}{{\overline{\mathit b}}}$ process via VBF with data of 126 fb${}^{-1}$ at $\mathit E_{{\mathrm {cm}}}$ = 13 TeV.
