${{\mathit H}}$ SIGNAL STRENGTHS IN DIFFERENT CHANNELS

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