Search for the HH → b͞b b͞b process via vector-boson fusion production using proton-proton collisions at s√ = 13 TeV with the ATLAS detector
A search for Higgs boson pair production via vector-boson fusion (VBF) in the b͞b b͞b final state is carried out with the ATLAS experiment using 126 fb⁻¹ of proton- proton collision data delivered at s√ = 13 TeV by the Large Hadron Collider. This search is sensitive to VBF production of additional h...
