Title: | Search for Higgs boson pair production in the bbbb final state from pp collisions at √s = 8 TeV with the ATLAS detector | Authors: | Santos, S. P. Amor dos Carvalho, J. Fiolhais, M. C. N. Galhardo, B. Veloso, F. Wolters, H. ATLAS Collaboration |
Issue Date: | 2015 | Publisher: | Springer Nature | Serial title, monograph or event: | European Physical Journal C | Volume: | 75 | Issue: | 9 | Abstract: | A search for Higgs boson pair production pp → hh is performed with 19.5 fb-1 of proton-proton collision data at √s = 8TeV, which were recorded by the ATLAS detector at the Large Hadron Collider in 2012. The decay products of each Higgs boson are reconstructed as a highmomentum bb system with either a pair of small-radius jets or a single large-radius jet, the latter exploiting jet substructure techniques and associated b-tagged track-jets. No evidence for resonant or non-resonant Higgs boson pair production is observed. The data are interpreted in the context of the Randall-Sundrum model with a warped extra dimension as well as the two-Higgs-doublet model. An upper limit on the cross-section for pp → G*KK → hh → bbbb of 3.2 (2.3) fb is set for aKaluza-Klein graviton G*KK mass of 1.0 (1.5)TeV, at the 95 % confidence level. The search for non-resonant Standard Model hh production sets an observed 95 % confidence level upper limit on the production cross-section σ(pp → hh → bbbb) of 202 fb, compared to a Standard Model prediction of σ(pp → hh → bbbb) = 3.6 ± 0.5fb. | URI: | https://hdl.handle.net/10316/109106 | DOI: | 10.1140/epjc/s10052-015-3628-x | Rights: | openAccess |
