1  AAD 2023Y constrain ${{\mathit \kappa}_{{{\gamma}}}}$ from Higgs production rates with ${{\mathit H}}$ $\rightarrow$ ${{\mathit \gamma}}{{\mathit \gamma}}$ with 139 fb${}^{-1}{{\mathit p}}{{\mathit p}}$ collision data at $\mathit E_{{\mathrm {cm}}}$ = 13 TeV. The quoted result is obtained assuming effective couplings ${{\mathit \kappa}_{{{gluon}}}}$ and ${{\mathit \kappa}_{{{\gamma}}}}$ for ${{\mathit g}}$ ${{\mathit g}}$ $\rightarrow$ ${{\mathit H}}$ and ${{\mathit H}}$ $\rightarrow$ ${{\mathit \gamma}}{{\mathit \gamma}}$, respectively and other couplings fixed to the SM values. See their Fig. 15.
2  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. Coupling strength modifiers including effective photon, ${{\mathit Z}}{{\mathit \gamma}}$ and gluon are measured. See their Fig. 6.
3  ${{\mathit B}_{{{inv}}}}$ = ${{\mathit B}_{{{undetected}}}}$ = 0 is assumed.
4  ${{\mathit B}_{{{inv}}}}$ floating, ${{\mathit B}_{{{undetected}}}}{}\geq{}$ 0, and ${{\mathit \kappa}_{{{V}}}}{}\leq{}$ 1 are assumed.
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. Coupling strength modifiers including effective photon, ${{\mathit Z}}{{\mathit \gamma}}$ and gluon are measured. See their Fig. 4 left.
