1  ATLAS 2022 report combined results (see their Extended Data Table 1) using up to 139 fb${}^{-1}$ of data at $\mathit E_{{\mathrm {cm}}}$ = 13 TeV, assuming ${\mathit m}_{{{\mathit H}}}$ = 125.09 GeV.
2  All modifiers($\kappa $) $>$ 0, and $\kappa _{c}$ = $\kappa _{t}$ ( ${{\mathit B}}$ $_{inv}$ = ${{\mathit B}}$ $_{undetected}$ = 0) are assumed. Only SM particles assume to contribute to the loop-induced processes.See their Fig. 5, which shows both $\kappa _{c}$ = $\kappa _{t}$ and$\kappa _{c}$ floating.
3  ${{\mathit B}}$ $_{inv}$ = ${{\mathit B}}$ $_{undetected}$ = 0 is assumed. Coupling strength modifiers including effective photon, ${{\mathit Z}}{{\mathit \gamma}}$ and gluon are measured. See their Fig. 6.
4  ${{\mathit B}}$ $_{inv}$ floating, ${{\mathit B}}$ $_{undetected}{}\geq{}$ 0, and $\kappa _{V}{}\leq{}$ 1 are assumed. Coupling strength modifiers including effective photon, ${{\mathit Z}}{{\mathit \gamma}}$ and gluon are measured. See their Fig. 6.
5  CMS 2022 report combined results (see their Extended Data Table 2) using up to 138 fb${}^{-1}$ of data at $\mathit E_{{\mathrm {cm}}}$ = 13 TeV, assuming ${\mathit m}_{{{\mathit H}}}$ = 125.38 GeV.
6  Only SM particles assume to contribute to the loop-induced processes. See their Fig. 3 right.
7  Coupling strength modifiers including effective photon, ${{\mathit Z}}{{\mathit \gamma}}$ and gluon are measured. See their Fig. 4 left.
