1  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 down quark Yukawa coupling assuming that the down quark and the Higgs interaction vertex shown in their Fig. 1 is the only parameter. See their Table II.
