Brussels, Monday 4 June 2018: The first observation of the simultaneous production of a Higgs particle with a top quark-antiquark pair was published today in the scientific journal Physical Review Letters. This major milestone, first reported by the Compact Muon Solenoid (CMS) Collaboration in April 2018 and today also reported by the ATLAS Collaboration, unambiguously demonstrates the interaction of the Higgs boson and the heaviest known subatomic particles, and is an important step forward in our understanding of the Higgs boson as the particle that creates the mass that makes atoms in the world around us stable. And up to now the interactions with quarks have not been tested well. As all atoms are made of quarks this means this results has substantial impact in our understanding of the world around us at a subatomic level.
