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 root 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 +/- 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.eninfo:eu-repo/semantics/openAccessHadron-Hadron Scattering (Experiments)Higgs PhysicsSearch for Higgs boson production in association with a high-energy photon via vector-boson fusion with decay into bottom quark pairs at ?s=13 TeV with the ATLAS detectorArticle2-s2.0-8510424963410.1007/JHEP03(2021)2683Q2Q1WOS:000638157200001
