The LHC has restarted and both beams have been circulating in the machine since 8 April, meaning that the start of the LHC beam commissioning during Easter is apparently not a constant of nature

The first beam-based physics of 2025 has started and more will follow soon. However, some unexpected challenges will cause a small delay in the restart of the LHC

Near-miss collisions at the Large Hadron Collider are shedding light on the dynamics of gluons, which contribute 99% to the mass of protons and neutrons

The Chamonix Workshop is in full swing, and the initial outlines of the 2025 LHC configuration and operational scenarios are beginning to take shape

Although the much-appreciated winter break is well behind us and most of us are back at work, the accelerator complex is still in hibernation – but not for much longer

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

The LHC was scheduled to conclude its outstanding 2024 run on 25 November, but a massive magnet quench brought it to an end two days early

The LHC’s tenth year of operation ends with exceptional data collection

Lead-ion physics at the LHC and the SPS North Area is already under way and progressing well. The final lead-ion user in the PS East Area started its physics run on 13 November

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