Abstract: A search for resonant and nonresonant pair production of Higgs bosons in the bb?+?- final state is presented. The search uses 36.1 fb-1 of pp collision data with s=13 TeV recorded by the ATLAS experiment at the LHC in 2015 and 2016. Decays of the ?-lepton pairs with at least one ? lepton decaying to final states with hadrons and a neutrino are considered. No significant excess above the expected background is observed in the data. The cross-section times branching ratio for nonresonant Higgs boson pair production is constrained to be less than 30.9 fb, 12.7 times the standard model expectation, at 95% confidence level. The data are also analyzed to probe resonant Higgs boson pair production, constraining a model with an extended Higgs sector based on two doublets and a Randall-Sundrum bulk graviton model. Upper limits are placed on the resonant Higgs boson pair production cross-section times branching ratio, excluding resonances X in the mass range 305 GeV<mX<402 GeV in the simplified hMSSM minimal supersymmetric model for tan?=2 and excluding bulk Randall-Sundrum gravitons GKK in the mass range 325 GeV<mGKK<885 GeV for k/MPl=1. © 2018 CERN, for the ATLAS Collaboration.
