HAYRAPETYAN 2026 search for ${{\mathit t}}{{\overline{\mathit t}}}{{\mathit H}}$, ${{\mathit H}}$ $\rightarrow$ ${{\mathit c}}{{\overline{\mathit c}}}$ together with the ${{\mathit t}}{{\overline{\mathit t}}}{{\mathit H}}$, ${{\mathit H}}$ $\rightarrow$ ${{\mathit b}}{{\overline{\mathit b}}}$ measurement using 138 fb${}^{-1}$ of ${{\mathit p}}{{\mathit p}}$ collision data at $\mathit E_{{\mathrm {cm}}}$ = 13 TeV. The quoted value is obtained by combining with the ${{\mathit V}}{{\mathit H}}$ channel and assuming ${{\mathit \kappa}_{{{b}}}}$ = 1.

AAD 2025Y present measurements of ${{\mathit V}}{{\mathit H}}$, ${{\mathit H}}$ $\rightarrow$ ${{\mathit b}}{{\overline{\mathit b}}}$ and ${{\mathit H}}$ $\rightarrow$ ${{\mathit c}}{{\overline{\mathit c}}}$ (${{\mathit V}}$ = ${{\mathit W}}$ , ${{\mathit Z}}$) using 140 fb${}^{-1}$ of ${{\mathit p}}{{\mathit p}}$ collision data at $\mathit E_{{\mathrm {cm}}}$ = 13 TeV. The quoted value is obtained assuming ${{\mathit \kappa}_{{{b}}}}$ = 1, all other couplings to their SM predictions, and only SM decays. The ratio of ${{\mathit \kappa}_{{{b}}}}$ and ${{\mathit \kappa}_{{{c}}}}$ is measured to be $\vert {{\mathit \kappa}_{{{c}}}}/{{\mathit \kappa}_{{{b}}}}\vert $ $<$ 3.6 at 95$\%$ CL.

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.

CHEKHOVSKY 2025L search for the production of a Higgs boson and one or more charm quarks (${{\mathit H}}+{{\mathit c}}$) with ${{\mathit H}}$ $\rightarrow$ ${{\mathit \gamma}}{{\mathit \gamma}}$ using 138 fb${}^{-1}$ of data at $\mathit E_{{\mathrm {cm}}}$ = 13 TeV. The quoted value is obtained assuming the SM rates for all other Higgs production processes.

HAYRAPETYAN 2025H search for ${{\mathit H}}$ $\rightarrow$ ${{\mathit J / \psi}}{{\mathit \gamma}}$, ${{\mathit J / \psi}}$ $\rightarrow$ ${{\mathit \mu}^{+}}{{\mathit \mu}^{-}}$ with 123 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 constrain the charm Yukawa coupling by comparing to ${{\mathit H}}$ $\rightarrow$ ${{\mathit \gamma}}{{\mathit \gamma}}$. An observed 95$\%$ CL interval of (-157, 199) is obtained for ${{\mathit \kappa}_{{{c}}}}/{{\mathit \kappa}_{{{\gamma}}}}$. The quoted value is obtained assuming ${{\mathit \kappa}_{{{\gamma}}}}$ = 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 charm Yukawa coupling assuming that the charm quark and the Higgs interaction vertex shown in their Fig. 1 is the only parameter. See their Table II.

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 ${{\mathit c}}{{\overline{\mathit c}}}$.

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 ${{\mathit \kappa}_{{{c}}}}/{{\mathit \kappa}_{{{\gamma}}}}$.

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 $\kappa _{c}$.

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.

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.
