One of the greatest mysteries in physics is why our Universe is made almost entirely of the normal matter that forms us and everything we touch. Every matter particle has a corresponding antiparticle ...

Il y a 70 ans aujourd’hui, Clyde Cowan, Frederick Reines et leurs collègues concluaient un quart de siècle de recherches en publiant dans la revue Science un article annonçant qu’ils avaient détecté ...

As outlined in our June article, CERN has a coordination structure in place to manage and oversee concurrent activities, including for the demanding LS3 period ahead. Clearly defined activities, ...

At CERN, scientists from around the world explore the fundamental structure of the Universe. They use large and complex instruments to push the boundaries of human knowledge.

The High-Luminosity Large Hadron Collider will increase the number of collisions to study fundamental components of matter in more detail. The High-Luminosity Large Hadron Collider (HiLumi LHC) ...
