Geneva, 14 August 2017. Physicists from the ATLAS experiment at CERN have found the first direct evidence of high energy light-by-light scattering, a very rare process in which two photons – particles of light – interact and change direction. The result, published today in Nature Physics, confirms one of the oldest predictions of quantum electrodynamics (QED).
In this section you will find CERN's latest updates and press releases.
Geneva, 3 August 2017. In a paper published today in Nature, the ALPHA experiment at CERN’s Antiproton Decelerator reports the first observation of the hyperfine structure of antihydrogen, the antimatter counterpart of hydrogen. These findings point the way to ever more detailed analyses of the structure of antihydrogen and could help understand any differences between matter and antimatter.
Geneva and Venice, 11 July 2017. The world’s particle physics community is meeting this week in Venice (Italy) for the EPS International Conference on High Energy Physics. Dozens of new results from the full existing datasets of the Large Hadron Collider experiments are being presented for the first time.
Geneva, 6 July 2017. Today at the EPS Conference on High Energy Physics in Venice, the LHCb experiment at CERN’s Large Hadron Collider has reported the observation of Ξcc++(Xicc++) a new particle containing two charm quarks and one up quark. The existence of this particle from the baryon family was expected by current theories, but physicists have been looking for such baryons with two heavy quarks for many years.
Today, the Republic of Slovenia becomes an Associate Member in the pre-stage to Membership at CERN. This follows official notification to CERN that the Republic of Slovenia has completed its internal approval procedures as required for the entry into force of the Agreement, signed in December 2016, granting that status to the country.
