Physicists Observe Simultaneous Production of Higgs Boson with Top Quark-Antiquark Pair

In July 2012, ATLAS (A Toroidal LHC ApparatuS) and CMS (Compact-Muon-Solenoid) experiments at CERN’s Large Hadron Collider jointly announced the discovery of the Higgs boson. The discovery confirmed the existence of the last missing elementary particle of the Standard Model, five decades after it was predicted theoretically. New results from ATLAS and CMS experiments reveal how strongly the Higgs boson interacts with the heaviest known elementary particle, the top quark. Observing this rare process is a significant milestone for the field of high-energy physics; it allows physicists to test critical parameters of the Higgs mechanism in the Standard Model.
