The NA62 Collaboration has dramatically reduced the uncertainty in its measurement of an extremely rare particle decay, in ...

CERN has reached a crucial milestone in the advancement of the High-Luminosity Large Hadron Collider (HiLumi LHC) project ...

Chiral effective field theory (EFT) provides a solid foundation for understanding low-energy interactions between pions, nucleons and external electroweak sources using the symmetry properties of QCD.

In the 1970s, physicists realized that there are very close ties between two of the four fundamental forces – the weak force and the electromagnetic force. The two forces can be described within the ...

The Scientific Policy Committee evaluates the scientific merit of activities proposed by physicists and makes recommendations on CERN’s scientific programme. Its members are scientists elected by ...

CERN, the European Organization for Nuclear Research, is one of the world’s largest and most respected centres for scientific research. Its business is fundamental physics, finding out what the ...

The Big Bang should have created equal amounts of matter and antimatter in the early universe. But today, everything we see from the smallest life forms on Earth to the largest stellar objects is made ...

Arts at CERN is delighted to announce that Geneva-based French-Congolese artist Monika Emmanuelle Kazi has been selected for ...

The Super Proton Synchrotron (SPS) is the second-largest machine in CERN’s accelerator complex. Measuring nearly 7 kilometres in circumference, it takes particles from the Proton Synchrotron and ...

In the 1860s, James Clerk Maxwell recognized the similarities between electricity and magnetism and developed his theory of a single electromagnetic force. A similar discovery came a century later, ...

Earth is subject to a constant bombardment of subatomic particles that can reach energies far higher than the largest machines A photomicrograph shows where high-energy electrons blazed through a film ...

CERN's cryogenic systems cool over 1000 magnets on the LHC to temperatures close to absolute zero, where matter takes on some unusual properties Cryogenics is the branch of physics that deals with the ...
