${{\mathit H}}$ SIGNAL STRENGTHS IN DIFFERENT CHANNELS

The ${{\mathit H}}$ signal strength in a particular final state ${{\mathit x}}{{\mathit x}}$ is given by the cross section times branching ratio in this channel normalized to the Standard Model (SM) value, $\sigma $ $\cdot{}$ B( ${{\mathit H}}$ $\rightarrow$ ${{\mathit x}}{{\mathit x}}$ ) $/$ ($\sigma $ $\cdot{}$ B( ${{\mathit H}}$ $\rightarrow$ ${{\mathit x}}{{\mathit x}}$ ))$_{{\mathrm {SM}}}$, for the specified mass value of ${{\mathit H}}$. For the SM predictions, see DITTMAIER 2011 , DITTMAIER 2012 , and HEINEMEYER 2013A. Results for fiducial and differential cross sections are also listed below.

1  AAD 2022W search for ${{\mathit V}}{{\mathit H}}$ , ${{\mathit H}}$ $\rightarrow$ ${{\mathit c}}{{\overline{\mathit c}}}$ (${{\mathit V}}$ = ${{\mathit W}}$ , ${{\mathit Z}}$ ) using 139 fb${}^{-1}$ of ${{\mathit p}}{{\mathit p}}$ collision data at $\mathit E_{{\mathrm {cm}}}$ = 13 TeV. The results are given for ${\mathit m}_{{{\mathit H}}}$ = 125 GeV.
2  The analysis of ${{\mathit V}}{{\mathit H}}$ , ${{\mathit H}}$ $\rightarrow$ ${{\mathit c}}{{\overline{\mathit c}}}$ is combined with ${{\mathit V}}{{\mathit H}}$ , ${{\mathit H}}$ $\rightarrow$ ${{\mathit b}}{{\overline{\mathit b}}}$ (AAD 2021AB). The ratio |${{\mathit \kappa}_{{c}}}/{{\mathit \kappa}_{{b}}}$| is constrained to be less than 4.5 at 95$\%$ CL. See their Fig. 7.
3  SIRUNYAN 2020AE use 35.9 fb${}^{-1}$ at of ${{\mathit p}}{{\mathit p}}$ collisions at $\mathit E_{{\mathrm {cm}}}$ = 13 TeV. The measured best fit value of ${\mathit \sigma (}$ ${{\mathit p}}$ ${{\mathit p}}$ $\rightarrow$ ${{\mathit V}}{{\mathit H}}{)}\cdot{}$B( ${{\mathit H}}$ $\rightarrow$ ${{\mathit c}}{{\overline{\mathit c}}}$ ) is $2.40$ ${}^{+1.12}_{-1.11}{}^{+0.65}_{-0.61}$ pb (equivalent to $<$ 4.5 pb at 95$\%$ CL upper limit, i.e. 70 times the standard model), where ${{\mathit V}}$ is ${{\mathit W}}$ $\rightarrow$ ${{\mathit \ell}}{{\mathit \nu}}$ , ${{\mathit Z}}$ $\rightarrow$ ${{\mathit \ell}}{{\mathit \ell}}$ , or ${{\mathit Z}}$ $\rightarrow$ ${{\mathit \nu}}{{\mathit \nu}}$ (${{\mathit \ell}}$ = ${{\mathit e}}$ , ${{\mathit \mu}}$ ). The quoted values are given for ${\mathit m}_{{{\mathit H}}}$ = 125 GeV.
4  The upper limit at 95$\%$ CL is 26 times the SM prediction. See their Fig. 2. The constraint on the charm Yukawa coupling modifier ${{\mathit \kappa}_{{c}}}$ is measured to be $\vert {{\mathit \kappa}_{{c}}}\vert <$8.5 at 95$\%$ CL. See their Fig. 4.
5  AABOUD 2018M use 36.1 fb${}^{-1}$ at of ${{\mathit p}}{{\mathit p}}$ collisions at $\mathit E_{{\mathrm {cm}}}$ = 13 TeV. The upper limit on ${\mathit \sigma (}$ ${{\mathit p}}$ ${{\mathit p}}$ $\rightarrow$ ${{\mathit Z}}{{\mathit H}}{)}\cdot{}$B( ${{\mathit H}}$ $\rightarrow$ ${{\mathit c}}{{\overline{\mathit c}}}$ ) is 2.7 pb at 95$\%$ CL. This corresponds to 110 times the standard model. The quoted values are given for ${\mathit m}_{{{\mathit H}}}$ = 125 GeV.
