title = "Search for nonresonant pair production of Higgs bosons in the bb¯bb¯ final state in pp collisions at √s = 13 TeV with the ATLAS detector",
abstract = "A search for nonresonant Higgs boson pair production in the 𝑏𝑏¯𝑏𝑏¯ final state is presented. The analysis uses 126 fb−1 of 𝑝𝑝 collision data at √𝑠 =13 TeV collected with the ATLAS detector at the Large Hadron Collider, and targets both the gluon-gluon fusion and vector-boson fusion production modes. No evidence of the signal is found and the observed (expected) upper limit on the cross section for nonresonant Higgs boson pair production is determined to be 5.4 (8.1) times the Standard Model predicted cross section at 95% confidence level. Constraints are placed on modifiers to the 𝐻𝐻𝐻 and 𝐻𝐻𝑉𝑉 couplings. The observed (expected) 2𝜎 constraints on the 𝐻𝐻𝐻 coupling modifier, 𝜅𝜆, are determined to be [−3.5,11.3] ([−5.4,11.4]), while the corresponding constraints for the 𝐻𝐻𝑉𝑉 coupling modifier, 𝜅2𝑉, are [−0.0,2.1] ([−0.1,2.1]). In addition, constraints on relevant coefficients are derived in the context of the Standard Model effective field theory and Higgs effective field theory, and upper limits on the 𝐻𝐻 production cross section are placed in seven Higgs effective field theory benchmark scenarios.",
