The disconnection of the LHC has begun
The 27 km circumference of the Large Hadron Collider (LHC) contains thousands of magnets of different types – dipoles, quadrupoles, sextupoles, octupoles, decapoles, etc. – which each play a very specific role. Among them are the inner triplets: sets of three quadrupoles (hence the name) located on either side of the four main LHC experiments

Exceptional transport operations to make way for HiLumi LHC
We often hear about the remarkable components of the accelerators, but transporting this equipment sometimes requires measures that are just as impressive. Over the course of the third long shutdown (LS3), which started this summer, entire sections of the Large Hadron Collider and its detectors will be dismantled in order to make room for the

ATLAS and CMS narrow in on double-Higgs production
Finding one Higgs boson was hard enough, but physicists at the Large Hadron Collider (LHC) are hunting for something even more elusive: pairs of Higgs bosons. At the recent International Conference on High Energy Physics 2026, the ATLAS and CMS Collaborations presented new constraints on the double-Higgs production rate, providing insight into how the Higgs

Accelerator Report: Beyond the LHC – CERN’s Beams Keep Science Moving
The Large Hadron Collider (LHC) may have entered Long Shutdown 3 (LS3), but across the rest of CERN’s accelerator complex operations remain as busy as ever. The LHC injector chain continues to provide proton beams for a broad range of users, including the ELENA antiproton community, the East and North Area experiments and the n_TOF

Oxygen collisions at the LHC show new indications of extreme state of matter
One year on from the first-ever collisions of oxygen at the Large Hadron Collider (LHC), the main LHC Collaborations – ALICE, ATLAS, CMS and LHCb – have each reported signs of the state of matter known as quark–gluon plasma (QGP) originating from these collisions. QGP is a state of matter that forms under intense pressure

Accelerator Report: Pushing the LHC towards HiLumi LHC conditions… and cut!
The final weeks of Run 3 for the LHC have been among the busiest of its entire operational period. With physics production successfully completed on 14 June, the machine entered a two-week programme dedicated to studies with high-intensity beams, followed by a quench campaign. These activities were scheduled after the completion of the physics programme

CERN bids farewell to the LHC and enters Long Shutdown 3
Today, the Large Hadron Collider (LHC), the world’s most powerful particle accelerator, comes to the end of an extraordinary chapter in its scientific journey. Following its final physics run, the accelerator has been switched off to begin CERN’s Long Shutdown 3 (LS3), a major programme of maintenance, consolidation, upgrades and installation work that will prepare the

LHCb discovers the final missing member of a doubly charmed particle family
The LHCb Collaboration has found a new particle consisting of one strange quark and two charm quarks. With this finding, the Collaboration has discovered the final member of a family of doubly charmed baryons – particles made up of two charm quarks and one other quark – and closes a chapter of a story that

Final collisions, new horizons
In the early hours of Sunday, 14 June, the experiments at the Large Hadron Collider (LHC) had their last hurrah. In the control rooms of ALICE, ATLAS, CMS and LHCb – the four major experiments at the accelerator – scientists watched the final collisions burst across their screens like colourful fireworks. The collisions for physics

LHC season finale, up next… HiLumi
Join scientists in the CERN Control Centre as the Large Hadron Collider (LHC) delivers its last collisions to its experiments before it is transformed into a high luminosity machine. Host Davide De Biasio will guide you through the journey of the world’s most powerful particle collider through conversations with the Head of LHC Operations, the
