Search for Higgs Boson Pair Production in the γγb b ¯ Final State Using pp Collision Data at √s = 8 TeV from the ATLAS Detector
Searches are performed for resonant and nonresonant Higgs boson pair production in the γγbb¯ final state using 20 fb-1 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 s...
