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

LHCb explores new territory during a special low-energy run
While the heavy-ion run season is in full swing at the LHC, let’s look back at the low-energy run that took place on 29 and 30 April. In yet another demonstration of the versatility of CERN’s accelerator complex, the LHC briefly departed from its standard high-energy operation to perform a special low-energy run dedicated primarily

Accelerator Report: From protons to ions – the LHC and its injectors prepare for the Run 3 finale
At 6 a.m. on 19 May, the LHC Run 3 proton physics programme officially came to an end. Thanks to the excellent performance and availability of both the LHC and its injector chain, this year’s integrated luminosity surpassed all expectations, with all four main LHC experiments recording values well above the original projections (fig. 1).

Cloudy with a chance of muons
When you want to capture an important moment in your life, you often take a photo. You could write down the key details instead – who you were with, where you were, the time of day – but this information might not be as impactful as a picture of the event. Physicists like to record

ATLAS acts as a cosmic-ray laboratory
The ATLAS Collaboration reports its first measurement of proton–oxygen collisions at the LHC, which recreate cosmic-ray interactions with Earth’s atmosphere

CMS looks deep inside quarks
The CMS Collaboration has probed deep inside quarks to search for potential building blocks within them

Accelerator Report: Excellent performance at the LHC
The LHC has successfully reached the nominal performance required for Run 3, marking an important milestone in the 2026 physics programme. It has now entered a special run with a reduced number of collisions per bunch crossing

Accelerator Report: HiLumi LHC beam reliability runs pave the way to the future
Dedicated HiLumi LHC beam test runs are currently taking place in the LHC injectors – a crucial step to guarantee that the HiLumi LHC can operate at peak performance from the very start of physics running, in 2030
