Searches for resonant and nonresonant pair-produced Higgs bosons (HH) decaying respectively into lnulnu, through either W or Z bosons, and bbbar. Based on a sample of proton-proton collisions at a centre-of-mass energy of 13 TeV corresponding to an integrated luminosity of 35.9 fb\u22121.\n\nThe main background processes, in decreasing order of importance, are ttbar, Drell-Yan, and single top quark production. \nDiboson, triboson, ttV and SM single Higgs boson production are also considered. \nOther contributions, such as W+jets or QCD multijet events with jets misidentified as leptons, are negligible.\nBackground simulation samples have been generated at NLO in QCD using powheg and MadGraph5 amc@nlo with FxFx merging and MadSpin. \nThe signal samples of gluon fusion production of two Higgs bosons, and of spin-0 or spin-2 narrow resonances decaying into two Higgs bosons, have been generated at leading order (LO) in QCD using MadGraph5 amc@nlo version 2.2.2.0. \nThe event generators used for both signal and background samples are interfaced with pythia 8.212.\nThe NNPDF 3.0 LO and NLO Parton Distribution Functions (PDF) are used.\nJets are reconstructed using a particle flow (PF) technique.\nPF candidates are clustered to form jets using the anti-kT clustering algorithm with a distance parameter of 0.4.\n\nRegion of interest is defined as:\n  - two leptons and two b-tagged jets\n  - (Pt_l1, Pt_l2) > (25GeV,15GeV) for the ee and mue channels \n  - (Pt_l1, Pt_l2) > (20GeV,10GeV) for the mumu channel\n  - (Pt_l1, Pt_l2) > (25GeV,10GeV) for the emu channel\n  - abs(eta_mu) < 2.4\n  - abs(eta_el) < 2.5\n  - pT_jet > 20GeV\n  - abs(eta_jet) < 2.4\n  - Delta_R(jet,lepton)>0.3\n  - 12 < m_ll < mZ \u221215 GeV","hasPart":[{"@id":"https://doi.org/10.17182/hepdata.83195.v1/t1","@type":"Dataset","description":"The dijet pT distributions in data and simulated events after requiring two leptons, two b-tagged jets, and 12 < m_ll...","name":"Figure 2a"},{"@id":"https://doi.org/10.17182/hepdata.83195.v1/t2","@type":"Dataset","description":"The dijet pT distributions in data and simulated events after requiring two leptons, two b-tagged jets, and 12 < m_ll...","name":"Figure 2b"},{"@id":"https://doi.org/10.17182/hepdata.83195.v1/t3","@type":"Dataset","description":"The dijet pT distributions in data and simulated events after requiring two leptons, two b-tagged jets, and 12 < m_ll...","name":"Figure 2c"},{"@id":"https://doi.org/10.17182/hepdata.83195.v1/t4","@type":"Dataset","description":"The mjj distribution in data and simulated events after requiring all selection criteria in the e+e- channel.
