This technical stop is particularly intense, being both shorter than usual, to maximise the limited time for physics, and very busy, to make essential preparations for LS3, which begins in June

A look back at a year of advances in science, technology and benefits to society

This incredibly rare phenomenon, observed at the CMS experiment, can help probe the fundamental forces of nature

A lot of the science from our accelerators is published long after collisions end, so storing experimental data for future physicists is crucial

The Large Hadron Collider gets a breath of fresh air as it collides beams of protons and oxygen ions for the very first time. Oxygen–oxygen and neon–neon collisions are also on the menu of the next few days

“Stable" particle beams are back in the LHC machine, marking the start of the 2025 physics data-taking campaign

For its 70th anniversary year, CERN honours its contributions to fundamental research, innovation and international collaboration.

For the next 17 days, every minute counts when it comes to taking lead–lead collision data

Fabiola Gianotti, CERN Director-General, was spokesperson of the ATLAS experiment at the Large Hadron Collider from 2009 to 2013 and responsible for announcing the discovery of the Higgs boson, alongside the CMS spokesperson

Jürgen Schukraft was the first spokesperson of the ALICE experiment at the Large Hadron Collider

We are optimistic that we will have a successful luminosity production period this summer

The LHC is performing well and the injector complex is treating its experimental users to a high level of beam availability
