Fig. 2.

Observed signal fraction per category for the $H\to \mathit{\gamma }\mathit{\gamma }$ analysis, and comparison to expected values for a SM Higgs boson and for a spin-2 particle with different choices of QCD couplings. a The 11 categories described in the text are displayed, corresponding to the $p_{\text{T}}^{\mathit{\gamma }\mathit{\gamma }}<300\text{GeV}$ selection; b the high-$p_{\text{T}}^{\mathit{\gamma }\mathit{\gamma }}$ category is discarded and the signal fractions are renormalised over the 10 remaining categories, corresponding to the $p_{\text{T}}^{\mathit{\gamma }\mathit{\gamma }}<125\text{GeV}$ selection
