The CMS and ATLAS experiments at CERN’s Large Hadron Collider have observed an unforeseen feature in the behaviour of top ...

With big outstanding questions and little hints of new physics, physicists are now rethinking some of their most fundamental assumptions. For centuries, scientists thought the universe was filled with ...

In a recent study, ALICE scientists measured the way that lead ions colliding in the LHC sometimes transform into gold and other new nuclei.

A large and unexpected excess of top quark pairs has the physics community excited, but the interpretation is still up for debate. In 1995, Alexander Grohsjean cut out a story from the local German ...

Yesterday, at the annual Rencontres de Moriond conference taking place in La Thuile, Italy, the LHCb collaboration at CERN reported a new milestone in our understanding of the subtle yet profound ...

Combining the DESI data with other experiments shows signs that the impact of dark energy may be weakening over time—and the standard model of how the universe works may need an update.

Neutrinos are notoriously aloof, but it’s not entirely their fault. Neutrinos are some of the most abundant particles in the universe, and they are everywhere. Every second, more than 6 trillion ...

Documenting the work of building the world’s largest neutrino experiment presents photographers with a unique set of challenges.

For more than 20 years in experimental particle physics and astrophysics, machine learning has been accelerating the pace of science, helping scientists tackle problems of greater and greater ...

The ATLAS and CMS experiments have successfully detected the production of a quartet of top quarks during high-energy proton collisions inside the Large Hadron Collider. Four-top production is 4,000 ...

For decades scientists have tried to find a way to measure the mass of the lightest matter particle known to exist. Three new approaches now have a chance to succeed.

The 2013 documentary Particle Fever follows physicists from the start-up of the LHC through the discovery of the Higgs boson. Where are those physicists now?
