A new independent measurement by the CMS experiment at the LHC is consistent with the existence of the most massive composite particle ever observed, the momentary union of a top quark and its antiquark
The experiment successfully transported a trap filled with antiprotons across CERN’s main site, a remarkable first step towards delivering antimatter to other European laboratories
Using machine-learning techniques, the ATLAS Collaboration has searched deep for signs of particles that could help answer some of the greatest mysteries of physics
Every day counts, so the LHC operations teams have mapped out a precise sequence of running phases to maximise the physics output during the machine’s final months
