The 12 founding member states of CERN in 1954. [13]The convention establishing CERN [14] was ratified on 29 September 1954 by 12 countries in Western Europe. [15] The acronym CERN originally represented the French words for Conseil Européen pour la Recherche Nucléaire ('European Council for Nuclear Research'), which was a provisional council for building the laboratory, established by 12 ...
The Large Hadron Collider (LHC) is the world's largest and highest-energy particle collider. [1][2] It was built by the European Organization for Nuclear Research (CERN) between 1998 and 2008 in collaboration with over 10,000 scientists and hundreds of universities and laboratories across more than 100 countries.

The High Luminosity Large Hadron Collider (HL-LHC; formerly referred to as HiLumi LHC, Super LHC, and SLHC) is an upgrade to the Large Hadron Collider, operated by the European Organization for Nuclear Research (CERN), located at the French-Swiss border near Geneva. From 2011 to 2020, the project was led by Lucio Rossi.
The Future Circular Collider (FCC) is a proposed particle accelerator with an energy significantly above that of previous circular colliders, such as the Super Proton Synchrotron, the Tevatron, and the Large Hadron Collider (LHC). [1][2] The FCC project is considering three scenarios for collision types: FCC-hh, for hadron -hadron collisions ...
After six months of cross checking, on September 23, 2011, the researchers announced that neutrinos had been observed traveling at faster-than-light speed. [6] Similar results were obtained using higher-energy (28 GeV) neutrinos, which were observed to check if neutrinos' velocity depended on their energy.
ATLAS is designed to detect these particles, namely their masses, momentum, energies, lifetime, charges, and nuclear spins. Experiments at earlier colliders, such as the Tevatron and Large Electron–Positron Collider, were also designed for general-purpose detection.
Canada was previously a full member but pulled out due to a lack of funding from the federal government. The lack of funding also resulted in Canada's withdrawing from its bid for the ITER site in 2003. Canada rejoined the project in 2020 via a cooperation agreement that focused on tritium and tritium-related equipment. [81]
The Large Electron–Positron Collider (LEP) was one of the largest particle accelerators ever constructed. It was built at CERN, a multi-national centre for research in nuclear and particle physics near Geneva, Switzerland. LEP collided electrons with positrons at energies that reached 209 GeV. It was a circular collider with a circumference ...
