Search for production of Higgs boson pairs in the four b quark final state using large-area jets in proton-proton collisions at √s=13 TeV

A search is presented for pair production of the standard model Higgs boson using data from proton-proton collisions at a centre-of-mass energy of 13 TeV, collected by the CMS experiment at the CERN LHC in 2016, and corresponding to an integrated luminosity of 35.9 fb−1 . The final state consist...
