Fig. 4.

The $H\to \mathit{\gamma }\mathit{\gamma }$ differential cross section for inclusive events as a function of (upper left) $p_{\mathrm{T}}^{\mathit{\gamma }\mathit{\gamma }}$, (upper right) $|y^{\mathit{\gamma }\mathit{\gamma }}|$, (lower left) $\mathrm{\Delta }{\mathit{\varphi }}^{\mathit{\gamma }\mathit{\gamma }}$, and (lower right) $|cos{\mathit{\theta }}^{\ast }|$. All the SM contributions are normalized to their cross section from Ref. [20]. Theoretical uncertainties in the renormalization and factorization scales, PDF, and branching fraction are added in quadrature. The error bars on data points reflect both statistical and systematic uncertainties. The last bin of $p_{\mathrm{T}}^{\mathit{\gamma }\mathit{\gamma }}$ distribution sums the events above 200$\text{GeV}$. For each graph, the bottom panel shows the ratio of data to theoretical predictions from the $\mathrm{P}\mathrm{O}\mathrm{W}\mathrm{H}\mathrm{E}\mathrm{G}$ generator
