A search for Higgs boson pair production in the bb¯¯bb¯¯ final state is carried out with up to 36.1 fb−1 of LHC proton-proton collision data collected at s√=13 TeV with the ATLAS detector in 2015 and 2016. Three benchmark ...
Observation of light-by-light scattering in ultraperipheral Pb+Pb collisions with the ATLAS detector
