1CHEKHOVSKY 2025G search for the ${{\mathit \gamma}}{{\mathit H}}$ production using a boosted Higgs boson recoiling against a high-energy photon with data of 138 fb${}^{-1}$ at $\mathit E_{{\mathrm {cm}}}$ = 13 TeV. The production cross section is constraint to be $\sigma _{{{\mathit \gamma}} {{\mathit H}}}$ $<$ $16.4$ fb at 95$\%$ CL. Constraints on four anomalous couplings involving ${{\mathit H}}{{\mathit Z}}{{\mathit \gamma}}$ and ${{\mathit H}}{{\mathit \gamma}}{{\mathit \gamma}}$ are shown in their Table I.
