A search for Higgs boson pair production in the bbbar WW* decay mode is performed in the bbbar l nu qq final state using 36.1 fb-1 of proton-proton collision data at a centre of-mass energy of 13TeV recorded with the ATLAS detector at the Large Hadron Collider. No evidence of events beyond the background expectation is found. Upper limits on the non-resonant pp -> HH production cross section of 10 pb and on the resonant production cross section as a function of the HH invariant mass are obtained. Resonant production limits are set for scalar and spin-2 graviton hypotheses in the mass range 500 to 3000 GeV.

Abstract

A search for Higgs boson pair production in the bbbar WW* decay mode is performed in the bbbar l nu qq final state using 36.1 fb-1 of proton-proton collision data at a centre of-mass energy of 13TeV recorded with the ATLAS detector at the Large Hadron Collider. No evidence of events beyond the background expectation is found. Upper limits on the non-resonant pp -> HH production cross section of 10 pb and on the resonant production cross section as a function of the HH invariant mass are obtained. Resonant production limits are set for scalar and spin-2 graviton hypotheses in the mass range 500 to 3000 GeV.
