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

Smarter decisions at the speed of physics
Smart and fast decision making is key when dealing with the onslaught of collisions at the LHC. At the High-Luminosity LHC (HiLumi LHC), the ATLAS and CMS experiments are expected to process detector data at rates corresponding to roughly a quarter of the 2025 global internet traffic. All in real time, as part of the

LHCb Collaboration discovers new proton-like particle
Composed of two charm quarks and one down quark, the doubly charmed particle is four times heavier than a proton

Machine learning to reveal more about LHC particle collisions
The CMS Collaboration demonstrates that machine learning can outperform traditional methods in the full reconstruction of particle collisions at the LHC

Groundbreaking CMS calorimeter for the High-Luminosity LHC
CMS has recently completed the first prototype slice of its innovative High-Granularity Calorimeter (HGCAL), which will be the largest silicon-based detector ever built

Accelerator Report: A very busy technical stop ahead of Long Shutdown 3
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
