abstract = {A search for a pair of neutral, scalar bosons with each decaying into two W
bosons is presented 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. This
search uses three production models: non-resonant and resonant Higgs boson pair production
and resonant production of a pair of heavy scalar particles. Three final states,
classified by the number of leptons, are analysed: two same-sign leptons, three leptons,
and four leptons. No significant excess over the expected Standard Model backgrounds is
observed. An observed (expected) 95% confidence-level upper limit of 160 (120) times the
Standard Model prediction of non-resonant Higgs boson pair production cross-section is set
from a combined analysis of the three final states. Upper limits are set on the production
cross-section times branching ratio of a heavy scalar X decaying into a Higgs boson pair
in the mass range of 260 GeV ≤ mX ≤ 500 GeV and the observed (expected) limits range
from 9.3 (10) pb to 2.8 (2.6) pb. Upper limits are set on the production cross-section times
branching ratio of a heavy scalar X decaying into a pair of heavy scalars S for mass ranges
of 280 GeV ≤ mX ≤ 340 GeV and 135 GeV ≤ mS ≤ 165 GeV and the observed (expected)
limits range from 2.5 (2.5) pb to 0.16 (0.17) pb.},
