The data correspond to an integrated luminosity of 19.7fb-1. The search considers H H resonances with masses between 1 and 3TeV, having final states of two b quark pairs. Each Higgs boson is produced with large momentum, and the hadronization products of the pair of b quarks can usually be reconstructed as single large jets. The background from multijet and t t ¯ events is significantly reduced by applying requirements related to the flavor of the jet, its mass, and its substructure. The signal would be identified as a peak on top of the dijet invariant mass spectrum of the remaining background events. No evidence is observed for such a signal. Upper limits obtained at 95 % confidence level for the product of the production cross section and branching fraction σ(gg→X)B(X→HH→bb¯bb¯) range from 10 to 1.5 fb for the mass of X from 1.15 to 2.0TeV, significantly extending previous searches. For a warped extra dimension theory with a mass scale ΛR= 1 TeV, the data exclude radion scalar masses between 1.15 and 1.55TeV. © 2016, CERN for the benefit of the CMS collaboration.</dc:description><dc:publisher>Springer Nature</dc:publisher><dc:date>2016</dc:date><dc:type>Article</dc:type><dc:identifier>https://rdlopen.rawdatalibrary.net/r/ebyu/14991</dc:identifier><dc:identifier>https://doi.org/10.1140/epjc/s10052-016-4206-6</dc:identifier><dc:identifier>1434-6044</dc:identifier><dc:language>en</dc:language><dc:relation>European Physical Journal C</dc:relation><dc:rights>info:eu-repo/semantics/openAccess</dc:rights><dc:type>info:eu-repo/semantics/article</dc:type><dc:identifier>https://ebyu-rdlopen.rawdatalibrary.net/tr/items/ebyu/14991</dc:identifier></oai_dc:dc></metadata></record></GetRecord></OAI-PMH>
