Abstract (data abstract)
CERN-LHC. Searches are performed for resonant and non-resonant Higgs boson pair production in the hh to gamma gamma b bbar final state using 20/fb of proton--proton collisions at a center-of-mass energy of 8 TeV recorded with the ATLAS detector at the CERN Large Hadron Collider. A 95% confidence level upper limit on the cross section times branching ratio of non-resonant production is set at 2.2 pb, while the expected limit is 1.0 pb. The corresponding limit observed for a narrow resonance ranges between 0.7 and 3.5 pb as a function of its mass. UPDATE (23 NOV 2014): corrected error in the limit setting that (dramatically) affects the uncertainties on the expected limits.
