A search is presented for narrow heavy resonances X decaying into pairs of Higgs bosons (H) in proton-proton collisions collected by the CMS experiment at the LHC at sqrt(s) = 8 TeV. The data correspond to an integrated luminosity of 19.7 inverse femtobarns. The search considers HH resonances with masses between 1 and 3 TeV, 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-bar 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 sigma(gg to X) B(X to HH to b b-bar b b-bar) range from 10 to 1.5 fb for the mass of X from 1.15 to 2.0 TeV, significantly extending previous searches. For a warped extra dimension theory with a mass scale Lambda[R] = 1 TeV, the data exclude radion scalar masses between 1.15 and 1.55 TeV.","hasPart":[{"@id":"https://doi.org/10.17182/hepdata.73976.v1/t1","@type":"Dataset","description":"Observed $m_\\mathrm{jj}$ spectrum (black points) compared with a background estimate (black line), obtained in background only hypothesis, for HPHP category....","name":"Table 1"},{"@id":"https://doi.org/10.17182/hepdata.73976.v1/t2","@type":"Dataset","description":"Observed $m_\\mathrm{jj}$ spectrum (black points) compared with a background estimate (black line), obtained in background only hypothesis, for HPLP category....","name":"Table 2"},{"@id":"https://doi.org/10.17182/hepdata.73976.v1/t3","@type":"Dataset","description":"Observed $m_\\mathrm{jj}$ spectrum (black points) compared with a background estimate (black line), obtained in background only hypothesis, for LPHP category....","name":"Table 3"},{"@id":"https://doi.org/10.17182/hepdata.73976.v1/t4","@type":"Dataset","description":"Observed and expected 95% CL upper limits on the product of cross section of a narrow resonance and the branching...","name":"Table 4"},{"@id":"https://doi.org/10.17182/hepdata.73976.v1/t5","@type":"Dataset","description":"Observed and expected 95% CL upper limits on the product of cross section of a narrow resonance and the branching...","name":"Table 5"},{"@id":"https://doi.org/10.17182/hepdata.73976.v1/t6","@type":"Dataset","description":"Observed and expected 95% CL upper limits on the product of cross section of a narrow resonance and the branching...","name":"Table 6"},{"@id":"https://doi.org/10.17182/hepdata.73976.v1/t7","@type":"Dataset","description":"Observed and expected 95% CL upper limits on the product of cross section and the branching fraction $\\sigma(gg \\to X)...","name":"Table 7"}],"identifier":[{"@type":"PropertyValue","propertyID":"HEPDataRecord","value":"https://www.hepdata.net/record/ins1424833?version=1"},{"@type":"PropertyValue","propertyID":"HEPDataRecordAlt","value":"https://www.hepdata.net/record/73976"}],"inLanguage":"en","name":"Search for heavy resonances decaying to two Higgs bosons in final states containing four b quarks","provider":{"@type":"Organization","name":"HEPData"},"publisher":{"@type":"Organization","name":"HEPData"},"url":"https://www.hepdata.net/record/ins1424833?version=1","version":1}
