The Higgs boson, the fundamental subatomic particle associated with the Higgs field, was first discovered in 2012 as part of the ATLAS and CMS experiments, both of which analyze data collected at CERN's Large Hadron Collider ...
In 2012 CERN's Large Hadron Collider (LHC) revolutionized particle physics when it was announced that the Higgs boson had been created and detected by the world's most powerful particle accelerator.
