4 days ago · CERN is one of the world’s largest and most respected centres for scientific research, focusing on fundamental physics to understand the Universe.

At CERN, we probe the fundamental structure of particles that make up everything around us. We do so using the world's largest and most complex scientific instruments.

CERN is home to a wide range of experiments. Scientists from institutes all over the world form experimental collaborations to carry out a diverse research programme, ensuring that CERN covers a wealth of topics in physics, from the Standard Model to supersymmetry and from exotic isotopes to cosmic rays. Several collaborations run experiments using the Large Hadron Collider (LHC), the most ...

11 hours ago · The year-end technical stop (YETS) activities in the accelerator complex’s first machines are nearing completion, but in the LHC about six weeks of work still lie ahead of us before the machine is handed over to the Operations group on 13 March for recommissioning. While having a well-defined and approved schedule is essential, an equally critical element for the 2025 run is establishing ...

Sep 19, 2024 · In February 2024, the SCE, SY and BE departments launched a pilot project for a new shuttle service between the Meyrin and Prévessin sites – the Meyrin–Prévessin Express. This reinforced version of Circuit 5 increased shuttles during peak times, including over lunchtime. After one year of service, the results and feedback are very positive. The Meyrin–Prévessin Express has therefore ...

Physicists and engineers at CERN use the world's largest and most complex scientific instruments to study the basic constituents of matter – fundamental particles. Subatomic particles are made to collide together at close to the speed of light. The process gives us clues about how the particles interact, and provides insights into the …

Jan 17, 2025 · 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 Universe is made of and how it works.

(Image: World Economic Forum) In January 2025, CERN Director-General Fabiola Gianotti attended the World Economic Forum’s annual meeting in Davos, Switzerland. She joined world-renowned ...

CERN's main focus is particle physics – the study of the fundamental constituents of matter – but the physics programme at the laboratory is much broader, ranging from nuclear to high-energy physics, from studies of antimatter to the possible effects of cosmic rays on clouds. Have we reached the end of the road in understanding nature? …

Nov 28, 2024 · The CERN Convention, signed at UNESCO in 1953, states that “the results of [CERN]’s experimental and theoretical work shall be published or otherwise made generally available.” (Image: CERN) The values of open science have always been at the heart of CERN’s mission, ever since the Organization’s inception. The CERN Convention, signed at UNESCO in 1953, states that “the results of ...
