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

1  SIRUNYAN 2018DQ search for ${{\mathit H}^{0}}$ $\rightarrow$ ${{\mathit \gamma}^{*}}{{\mathit \gamma}}$ , ${{\mathit \gamma}^{*}}$ $\rightarrow$ ${{\mathit \mu}}{{\mathit \mu}}$ in 35.9 fb${}^{-1}$ of ${{\mathit p}}{{\mathit p}}$ collisions at $\mathit E_{{\mathrm {cm}}}$ = 13 TeV. The mass of ${{\mathit \gamma}^{*}}$ is smaller than 50 GeV except in ${{\mathit J / \psi}}$ and ${{\mathit \Upsilon}}$ mass regions. The quoted signal strength (see their Figs. 6 and 7) is given for ${\mathit m}_{{{\mathit H}^{0}}}$ = 125 GeV.

See their Fig. 6 for limits on individual channels.
