1  AAD 2023C combine results of ${{\mathit H}}$ $\rightarrow$ ${{\mathit \gamma}}{{\mathit \gamma}}$ and ${{\mathit H}}$ $\rightarrow$ ${{\mathit Z}}{{\mathit Z}^{*}}$ $\rightarrow$ 4 ${{\mathit \ell}}$ (${{\mathit \ell}}$ = ${{\mathit e}}$ , ${{\mathit \mu}}$) using 139 fb${}^{-1}$ at $\mathit E_{{\mathrm {cm}}}$ = 13 TeV. The Higgs boson transverse momentum (${{\mathit p}^{H}_{T}}$) distribution constrains $\kappa _{b}$ and $\kappa _{c}$, assuming other couplings fixed to the SM values. The $\kappa _{c}$ is obtained using the ${{\mathit p}^{H}_{T}}$ shape and normalisation. Other cases are given in their Tables 6 and 7. See their Table 8 for results combined with ${{\mathit V}}{{\mathit H}}$, ${{\mathit H}}$ $\rightarrow$ ${{\mathit b}}{{\overline{\mathit b}}}$ and ${{\mathit c}}{{\overline{\mathit c}}}$.
2  AAD 2023CD search for ${{\mathit H}}$ $\rightarrow$ ${{\mathit J / \psi}}{{\mathit \gamma}}$, ${{\mathit J / \psi}}$ $\rightarrow$ ${{\mathit \mu}^{+}}{{\mathit \mu}^{-}}$ with 138 fb${}^{-1}$ of ${{\mathit p}}{{\mathit p}}$ collision data at $\mathit E_{{\mathrm {cm}}}$ = 13 TeV. They interpret the ${{\mathit H}}$ $\rightarrow$ ${{\mathit J / \psi}}{{\mathit \gamma}}$ search to constraint the charm Yukawa coupling by comparing to ${{\mathit H}}$ $\rightarrow$ ${{\mathit \gamma}}{{\mathit \gamma}}$. An observed 95$\%$ CL interval of (-133, 175) is obtained for ${{\mathit \kappa}_{{{c}}}}/{{\mathit \kappa}_{{{\gamma}}}}$.
3  HAYRAPETYAN 2023 measure the cross sections for ${{\mathit p}}$ ${{\mathit p}}$ $\rightarrow$ ${{\mathit H}}$ $\rightarrow$ ${{\mathit Z}}{{\mathit Z}^{*}}$ $\rightarrow$ 4 ${{\mathit \ell}}$ (${{\mathit \ell}}$ = ${{\mathit e}}$ , ${{\mathit \mu}}$) using 138 fb${}^{-1}$ at $\mathit E_{{\mathrm {cm}}}$ = 13 TeV. The $\kappa _{c}$ is obtained from the $p_T$ differential cross section of the ggF production employing the dependence of the branching fraction of $\kappa _{b}$ and $\kappa _{c}$.
4  TUMASYAN 2023AH search for ${{\mathit V}}{{\mathit H}}$, ${{\mathit H}}$ $\rightarrow$ ${{\mathit c}}{{\overline{\mathit c}}}$ (${{\mathit V}}$ = ${{\mathit W}}$ , ${{\mathit Z}}$) using 138 fb${}^{-1}$ of ${{\mathit p}}{{\mathit p}}$ collision data at $\mathit E_{{\mathrm {cm}}}$ = 13 TeV. The quoted values are obtained from the measured signal strength in the $\kappa $-framework, where only the Higgs decay width for ${{\mathit H}}$ $\rightarrow$ ${{\mathit c}}{{\overline{\mathit c}}}$ is changed while assuming all the other decay widths and the production cross section to be SM ones. The quoted values are given for ${\mathit m}_{{{\mathit H}}}$ = 125.38 GeV.
5  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, and all modifiers ($\kappa $) $>$ 0 (${{\mathit B}}_{inv}$ = ${{\mathit B}}_{undetected}$ = 0). 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.
