| Abstract: A search for resonant Higgs bosons pair production decaying into $ \mathrm{b} \overline{\mathrm{b}} \mathrm{W} \mathrm{W} $ with subsequent $ \mathrm{W}\mathrm{W} $ decays into two leptons and two neutrinos, $\mathrm{X} \to \mathrm{H}\mathrm{H} \to \mathrm{b} \overline{\mathrm{b}} \mathrm{W} \mathrm{W} \to \mathrm{b}\overline{\mathrm{b}} \ell\nu \ell\nu$, is presented. The analysis is based on a sample of proton-proton collisions at $\sqrt{s} =$ 13 TeV at the LHC corresponding to an integrated luminosity of 2.3 fb$^{-1}$. Masses are considered in the range between ${m}_{\mathrm{X}} = $ 260 GeV and 900 GeV. The search focuses on the invariant mass distribution of the b-jet pair, searching for a resonant-like excess compatible with the H boson mass in combination with a boosted decision tree discriminant based on kinematic information. Data and predictions from the standard model are in agreement within systematic uncertainties. For mass hypotheses from ${m}_{\mathrm{X}} =$ 500 GeV to $ {m}_{\mathrm{X}} =$ 900 GeV, the data are observed (expected) to exclude a production cross-section times branching ratio of a spin-0 particle from 174 to 101 (135 to 75.8) fb. | ||
