Search for Higgs boson pair production in the bbbb final state from pp collisions at √s = 8 TeV with the ATLAS detector
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...
