Abstract (data abstract)
CERN-ATLAS. Search for Higgs boson production in association with a high-energy photon via vector-boson fusion with decay into bottom quark pairs at $$\sqrt{s}$$ = 13 TeV with the ATLAS detector A search is presented for the production of the Standard Model Higgs boson in association with a high-energy photon. With a focus on the vector-boson fusion process and the dominant Higgs boson decay into $$b$$-quark pairs, the search benefits from a large reduction of multijet background compared to more inclusive searches. Results are reported from the analysis of 132 fb$^{-1}$ of $$pp$$ collision data at $$\sqrt{s}=13$$ TeV collected with the ATLAS detector at the LHC. The measured Higgs boson signal yield in this final-state signature is $$1.3 \pm 1.0$$ times the Standard Model prediction. The observed significance of the Higgs boson signal above the background is $$1.3$$ standard deviations, compared to an expected significance of $$1.0$$ standard deviations.
