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
BASE experiment at CERN succeeds in transporting antimatter
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
ALICE sees new sign of primordial plasma in proton collisions
The ALICE Collaboration takes a step further in addressing the question of whether a quark–gluon plasma can be formed in proton–proton and proton–nucleus collisions
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
The final physics season at the LHC has just kicked off! The experiments will record collisions until the end of June, when work will begin on transforming the machine into a high-luminosity accelerator.
Scientists at CERN have triggered the complex cooldown of a 95-m-long test stand that reproduces the underground configuration of innovative technologies for the Large Hadron Collider’s high-luminosity upgrade
