#### ${{\mathit H}^{0}}$ SIGNAL STRENGTHS IN DIFFERENT CHANNELS

The ${{\mathit H}^{0}}$ 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( ${{\mathit H}^{0}}$ $\rightarrow$ ${{\mathit x}}{{\mathit x}}$ ) $/$ ($\sigma$ $\cdot{}$ B( ${{\mathit H}^{0}}$ $\rightarrow$ ${{\mathit x}}{{\mathit x}}$ ))$_{{\mathrm {SM}}}$, for the specified mass value of ${{\mathit H}^{0}}$ . For the SM predictions, see DITTMAIER 2011 , DITTMAIER 2012 , and HEINEMEYER 2013A. Results for fiducial and differential cross sections are also listed below.

 1 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 ${\mathit \sigma (}$ ${{\mathit p}}$ ${{\mathit p}}$ $\rightarrow$ ${{\mathit V}}{{\mathit H}^{0}}{)}\cdot{}$B( ${{\mathit H}^{0}}$ $\rightarrow$ ${{\mathit c}}{{\overline{\mathit c}}}$ ) 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 ${\mathit m}_{{{\mathit H}^{0}}}$ = 125 GeV.
 2 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 ${\mathit \sigma (}$ ${{\mathit p}}$ ${{\mathit p}}$ $\rightarrow$ ${{\mathit Z}}{{\mathit H}^{0}}{)}\cdot{}$B( ${{\mathit H}^{0}}$ $\rightarrow$ ${{\mathit c}}{{\overline{\mathit c}}}$ ) is 2.7 pb at 95$\%$ CL. This corresponds to 110 times the standard model. The quoted values are given for ${\mathit m}_{{{\mathit H}^{0}}}$ = 125 GeV.
