The LHC is currently shut down. Teams will now dismantle 1.2 kilometres of the accelerator to install the new HiLumi LHC equipment. This will be connected to the equipment installed in the new HiLumi ...

This phase, known as “Long Shutdown 3” or “LS3”, is expected to last up to four years and will involve thousands of experts across CERN’s sites and tunnels. The work will cover civil engineering, ...

Mick Storr was the face of CERN’s Teacher Programmes and a mentor to teachers around the world. (Image: Anna Pantelia / CERN) It was with profound sadness that we learned of the passing of Mick Storr ...

The Standard Model explains how the basic building blocks of matter interact, governed by four fundamental forces. The theories and discoveries of thousands of physicists since the 1930s have resulted ...

The second-largest machine in CERN’s accelerator complex provides a stepping stone between the Proton Synchrotron and the LHC The SPS became the workhorse of CERN’s particle physics programme when it ...

At any moment in time, CERN is training thousands of young people across a large spectrum of competencies, providing society with a continuous stream of talent in science, technology, engineering and ...

Update: did you enjoy our April Fool’s day story? While we won’t be racing karts through the tunnel, we are gearing up for major works to prepare for HiLumi LHC and its new technologies. The image is ...

CERN has revised its schedule for its accelerator complex. The Large Hadron Collider (LHC) is currently in its third period of physics data taking (Run 3), and this will now be extended until July ...

Limiting energy consumption is a major concern in the development of any new machine. In electron-positron colliders—such as the “Higgs factories” currently being conceived to study the enigmatic ...

A candidate collision event for a pair of Higgs bosons, with one boson decaying into two photons and the other into a pair of bottom quarks. The two particle jets originating from the bottom quarks ...

A simplified visualisation of the 23 exotic hadrons discovered so far at the LHC. Each particle contains at least one charm quark and a mixture of up, down and strange quarks. Quark and hadron masses ...
