# ${{\boldsymbol H}^{0}}$ 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  AABOUD 2017AW search for ${{\mathit H}^{0}}$ $\rightarrow$ ${{\mathit Z}}{{\mathit \gamma}}$ , ${{\mathit Z}}$ $\rightarrow$ ${{\mathit e}}{{\mathit e}}$ , ${{\mathit \mu}}{{\mathit \mu}}$ in 36.1 fb${}^{-1}$ of ${{\mathit p}}{{\mathit p}}$ collisions at $\mathit E_{{\mathrm {cm}}}$ = 13 TeV. The quoted signal strength is given for ${\mathit m}_{{{\mathit H}^{0}}}$ = 125.09 GeV. The upper limit on the branching ratio of ${{\mathit H}^{0}}$ $\rightarrow$ ${{\mathit Z}}{{\mathit \gamma}}$ is 1.0$\%$ at 95$\%$ CL assuming the SM Higgs boson production.
2  AAD 2014J search for ${{\mathit H}^{0}}$ $\rightarrow$ ${{\mathit Z}}{{\mathit \gamma}}$ $\rightarrow$ ${{\mathit \ell}}{{\mathit \ell}}{{\mathit \gamma}}$ in 4.5 fb${}^{-1}$ of ${{\mathit p}}{{\mathit p}}$ collisions at $\mathit E_{{\mathrm {cm}}}$ = 7 TeV and 20.3 fb${}^{-1}$ at $\mathit E_{{\mathrm {cm}}}$ = 8 TeV. The quoted signal strength is given for ${\mathit m}_{{{\mathit H}^{0}}}$ = 125.5 GeV.
3  CHATRCHYAN 2013BK search for ${{\mathit H}^{0}}$ $\rightarrow$ ${{\mathit Z}}{{\mathit \gamma}}$ $\rightarrow$ ${{\mathit \ell}}$ ${{\mathit \ell}}{{\mathit \gamma}}$ in 5.0 fb${}^{-1}$ of ${{\mathit p}}{{\mathit p}}$ collisions at $\mathit E_{{\mathrm {cm}}}$ = 7 TeV and 19.6 fb${}^{-1}$ at $\mathit E_{{\mathrm {cm}}}$ = 8 TeV. A limit on cross section times branching ratio which corresponds to ($4 - 25$) times the expected Standard Model cross section is given in the range ${\mathit m}_{{{\mathit H}^{0}}}$ = $120 - 160$ GeV at 95$\%$ CL. The quoted limit is given for ${\mathit m}_{{{\mathit H}^{0}}}$ = 125 GeV, where 10 is expected for no signal.
