1  CHEKHOVSKY 2025G search for the ${{\mathit H}}{{\mathit \gamma}}$ production with ${{\mathit H}}$ $\rightarrow$ ${{\mathit Z}}{{\mathit Z}^{*}}$ $\rightarrow$ 4 ${{\mathit \ell}}$ (${{\mathit \ell}}$ = ${{\mathit e}}$, ${{\mathit \mu}}$) decay channel with data of 138 fb${}^{-1}$ at $\mathit E_{{\mathrm {cm}}}$ = 13 TeV. Coupling modifiers ${{\mathit \kappa}_{{{u}}}}$, ${{\mathit \kappa}_{{{d}}}}$, ${{\mathit \kappa}_{{{s}}}}$ and ${{\mathit \kappa}_{{{c}}}}$ are simultaneously obtained assuming the SM Yukawa couplings for the bottom and top quarks (${{\mathit \kappa}_{{{b}}}}$ = 1 , ${{\mathit \kappa}_{{{t}}}}$ = 1) and constraining the ${{\mathit H}}{{\mathit V}}{{\mathit V}}$ couplings (${{\mathit \kappa}^{2}_{ZZ}}{}\leq{}$1, ${{\mathit \kappa}^{2}_{WW}}$ = ${{\mathit \kappa}^{2}_{ZZ}}$). See their Tables III.
2  HAYRAPETYAN 2024D search for the ${{\mathit H}}{{\mathit \gamma}}$ production using ${{\mathit H}}$ $\rightarrow$ ${{\mathit W}}{{\mathit W}^{*}}$ $\rightarrow$ ${{\mathit e}}{{\mathit \nu}}{{\mathit \mu}}{{\mathit \nu}}$ with 138 fb${}^{-1}$ of ${{\mathit p}}{{\mathit p}}$ collision data at $\mathit E_{{\mathrm {cm}}}$ = 13 TeV. They interpret the ${{\mathit H}}{{\mathit \gamma}}$ search to constraint the up quark Yukawa coupling assuming that the up quark and the Higgs interaction vertex shown in their Fig. 1 is the only parameter. See their Table II.
