All CERN accelerators now on the road to HiLumi
CERN’s injector complex and Antimatter Factory took their final steps towards Long Shutdown 3 (LS3) this morning, as the last particle beams were extracted and the machines fell silent. This milestone follows the shutdown of the Large Hadron Collider (LHC) in June, which marked the beginning of LS3 for the Laboratory’s flagship accelerator. While the

CMS explores subtle matter–antimatter difference using beauty mesons
The CMS experiment uses its largest sample of beauty mesons to date to perform a high-precision test of subtle differences between matter and antimatter

Getting under the skin of atomic nuclei using antimatter
Researchers at the AEgIS experiment have piloted a new method to delve into the heart of atoms. This proof-of-principle study, recently reported in Physical Review Research, shows how antiprotons – the antimatter counterparts of protons – could be used to probe the outer edges of a wider range of atomic nuclei. And with CERN’s recent

ALPHA measures tiny energy gap in antimatter with improved precision
Researchers at the ALPHA experiment have achieved a hundredfold improvement in their measurement of a feature of the antimatter counterpart of the hydrogen atom. The result, published today in Nature, allows a precise comparison of hydrogen and antihydrogen. In this study, the ALPHA Collaboration measured the ground-state hyperfine splitting of the antihydrogen atom, which comprises

Accelerator Report: The 2026 run will be short but intense
Every day counts, so the LHC operations teams have mapped out a precise sequence of running phases to maximise the physics output during the machine’s final months
