CERN Accelerating science

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

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

Composed of two charm quarks and one down quark, the doubly charmed particle is four times heavier than a proton

Study of the one-in-ten-billion kaon decay allows researchers to stress-test the Standard Model of particle physics

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

The CMS Collaboration demonstrates that machine learning can outperform traditional methods in the full reconstruction of particle collisions at the LHC

A pioneer of CERN’s experimental programme in the 1950s, he was one of the most influential figures in high-energy physics

The latest edition of the CERN Courier magazine explores what the High-Luminosity LHC will be able to say about the distant past and future of the Universe
