${{\boldsymbol H}^{0}}$ 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.

2  AABOUD 2018BO use 36.1 fb${}^{-1}$ of ${{\mathit p}}{{\mathit p}}$ collisions at $\mathit E_{{\mathrm {cm}}}$ = 13 TeV. The signal strengths for the individual production modes are: $0.81$ ${}^{+0.19}_{-0.18}$ for gluon fusion, $2.0$ ${}^{+0.6}_{-0.5}$ for vector boson fusion, $0.7$ ${}^{+0.9}_{-0.8}$ for ${{\mathit V}}{{\mathit H}^{0}}$ production (${{\mathit V}}$ = ${{\mathit W}}$, ${{\mathit Z}}$), and $0.5$ $\pm0.6$ for ${{\mathit t}}{{\overline{\mathit t}}}{{\mathit H}^{0}}$ and ${{\mathit t}}{{\mathit H}^{0}}$ production. Other measurements of cross sections and couplings are summarized in their Section 10. The quoted values are given for ${\mathit m}_{{{\mathit H}^{0}}}$ = 125.09 GeV.
3  AAD 2016AN perform fits to the ATLAS and CMS data at $\mathit E_{{\mathrm {cm}}}$ = 7 and 8 TeV. The signal strengths for individual production processes are $1.10$ ${}^{+0.23}_{-0.22}$ for gluon fusion, $1.3$ $\pm0.5$ for vector boson fusion, $0.5$ ${}^{+1.3}_{-1.2}$ for ${{\mathit W}}{{\mathit H}^{0}}$ production, $0.5$ ${}^{+3.0}_{-2.5}$ for ${{\mathit Z}}{{\mathit H}^{0}}$ production, and $2.2$ ${}^{+1.6}_{-1.3}$ for ${{\mathit t}}{{\overline{\mathit t}}}{{\mathit H}^{0}}$ production.
4  AAD 2016AN: In the fit, relative production cross sections are fixed to those in the Standard Model. The quoted signal strength is given for ${\mathit m}_{{{\mathit H}^{0}}}$ = 125.09 GeV.

The quoted signal strength is given for ${\mathit m}_{{{\mathit H}^{0}}}$ = 125 GeV.
6  SIRUNYAN 2019L measure fiducial and differential cross sections of the process ${{\mathit p}}$ ${{\mathit p}}$ $\rightarrow$ ${{\mathit H}^{0}}$ $\rightarrow$ ${{\mathit \gamma}}{{\mathit \gamma}}$ at $\mathit E_{{\mathrm {cm}}}$ = 13 TeV with 35.9 fb${}^{-1}$. See their Figs. $4 - 11$.

The Higgs mass is floated in the measurement of a signal strength. The result is $1.18$ ${}^{+0.12}_{-0.11}$(stat.)${}^{+0.09}_{-0.07}$(syst.)${}^{+0.07}_{-0.06}$(theory), which is largely insensitive to the Higgs mass around 125 GeV.
