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

The quoted signal strengths are given for ${\mathit m}_{{{\mathit H}^{0}}}$ = 125.09 GeV. In the fit, relative branching ratios and relative production cross sections are fixed to those in the Standard Model.
5  AALTONEN 2013M combine all Tevatron data from the CDF and D0 Collaborations with up to 10.0 fb${}^{-1}$ and 9.7 fb${}^{-1}$, respectively, of ${{\mathit p}}{{\overline{\mathit p}}}$ collisions at $\mathit E_{{\mathrm {cm}}}$ = 1.96 TeV.

The total cross section for Higgs boson production is measured to be $61.1$ $\pm6.0$ $\pm3.7$ pb using ${{\mathit H}^{0}}$ $\rightarrow$ ${{\mathit \gamma}}{{\mathit \gamma}}$ and ${{\mathit H}^{0}}$ $\rightarrow$ ${{\mathit Z}}{{\mathit Z}^{*}}$ channels. Several coupling measurements in the $\kappa$-framework are performed.
