KHACHATRYAN 2016BQ search for ${{\mathit H}}{{\mathit H}}$ production using ${{\mathit H}}$ ${{\mathit H}}$ $\rightarrow$ ${{\mathit \gamma}}{{\mathit \gamma}}{{\mathit b}}{{\overline{\mathit b}}}$ with data of 19.7 fb${}^{-1}$ at $\mathit E_{{\mathrm {cm}}}$ = 8 TeV. The upper limit on the ${{\mathit g}}$ ${{\mathit g}}$ $\rightarrow$ ${{\mathit H}}{{\mathit H}}$ $\rightarrow$ ${{\mathit \gamma}}{{\mathit \gamma}}{{\mathit b}}{{\overline{\mathit b}}}$ production is measured to be 1.85 fb, which corresponds to about 74 times the SM prediction and is translated into 0.71 pb for ${{\mathit g}}$ ${{\mathit g}}$ $\rightarrow$ ${{\mathit H}}{{\mathit H}}$ production cross section.

AAD 2015CE search for ${{\mathit H}}{{\mathit H}}$ production using ${{\mathit H}}$ ${{\mathit H}}$ $\rightarrow$ ${{\mathit b}}{{\overline{\mathit b}}}{{\mathit \tau}}{{\mathit \tau}}$ and ${{\mathit H}}$ ${{\mathit H}}$ $\rightarrow$ ${{\mathit \gamma}}{{\mathit \gamma}}{{\mathit W}}{{\mathit W}}$ with data of 20.3 fb${}^{-1}$ at $\mathit E_{{\mathrm {cm}}}$ = 8 TeV. These results are then combined with the published results of the ${{\mathit H}}$ ${{\mathit H}}$ $\rightarrow$ ${{\mathit \gamma}}{{\mathit \gamma}}{{\mathit b}}{{\overline{\mathit b}}}$ and ${{\mathit H}}$ ${{\mathit H}}$ $\rightarrow$ ${{\mathit b}}{{\overline{\mathit b}}}{{\mathit b}}{{\overline{\mathit b}}}$, which use data of up to 20.3 fb${}^{-1}$ at $\mathit E_{{\mathrm {cm}}}$ = 8 TeV. The upper limits on the ${{\mathit g}}$ ${{\mathit g}}$ $\rightarrow$ ${{\mathit H}}{{\mathit H}}$ production cross section are measured to be 1.6 pb, 11.4 pb, 2.2 pb and 0.62 pb from ${{\mathit b}}{{\overline{\mathit b}}}{{\mathit \tau}}{{\mathit \tau}}$, ${{\mathit \gamma}}{{\mathit \gamma}}{{\mathit W}}{{\mathit W}}$, ${{\mathit \gamma}}{{\mathit \gamma}}{{\mathit b}}{{\overline{\mathit b}}}$ and ${{\mathit b}}{{\overline{\mathit b}}}{{\mathit b}}{{\overline{\mathit b}}}$, respectively. The combined upper limit is 0.69 pb, which corresponds to about 70 times the SM prediction. The quoted results are given for ${\mathit m}_{{{\mathit H}}}$ = 125.4 GeV. See their Table 4.
