In this combination, three independent signal strengths gg → H → γγ, VBF+VH → H → γγ, and H → ZZ → 4l are proﬁled together with all other nuisance parameters. (Right) 2D 68% CL contours for a hypothesized Higgs boson mass m_{H} and signal strength σ/σ_{SM} for the γγ and 4l, and their combination.

Summary of the fits for deviations in the coupling for the LHC XS WG benchmark models (arXiv:1209.0040). For each model, the best fit values of the most interesting parameters are shown, with the corresponding 68% and 95% CL intervals, and the overall pvalue p_{SM} of the SM Higgs hypothesis is given. The list of parameters for each model and the numerical values of the intervals are provided in Table 3 of the PAS.

The result of the fit when extending the model to allow for beyondSM decays while restricting the effective coupling to vector bosons to not exceed unity (κ_{V} ≤ 1.0) is also shown.
