Commercial software can’t keep pace with experimental precision when it comes to large-scale computer-algebra calculations in quantum field theory. Maintained by a single theorist for decades, FORM is ...

What is the fate of the universe? Why is there more matter than antimatter? What lurks beyond the Standard Model? Valentina Cairo and Steven Lowette explore the physics reach of the High-Luminosity ...

Gianluigi Arduini, Philip Burrows and Jacqueline Keintzel report on the findings of a working group mandated to compare seven proposals for CERN’s next large-scale collider. The view from Le Reculet ...

Astrophysical constraints stake out 90 orders of magnitude for the mass of dark-matter particles. Clara Murgui surveys this vast terrain before zooming in on a particularly interesting region of ...

In lead collisions at the LHC, some of the strongest electromagnetic fields in the universe bombard the inside of the beam pipe with radioactive gold. By following the collision fragments, John Jowett ...

Subatomic physics has shaped both the conduct of war and the treatment of cancer. Joseph Rotblat, who left the Manhattan Project on moral grounds and later advanced radiotherapy, embodies this dual ...

Mature design The CEPC Study Group has published a technical design report for its reference detector. Credit: CEPC Study Group 2025 arXiv:2510.05260 In October, the Circular Electron–Positron ...

With the story of quarkonia entering its final chapter, John Ellis shares personal recollections of five decades of discoveries and debates about the simplest composite object in QCD, whose history is ...

Orthodox quantum mechanics is empirically flawless, but founded on an awkward interface between quantum systems and classical probes. In this feature, Carlo Rovelli – himself the originator of the ...

Laser calibration Technical improvements by Fermilab’s Muon g-2 collaboration achieved a systematic uncertainty of 78 ppb on quantum corrections to the magnetic moment of the muon. Credit: R Hahn ...

David Wallace argues for the ‘decoherent view’ of quantum mechanics, where at the fundamental level there is neither probability nor wavefunction collapse – and for its purest incarnation, the ...

Nuria Catalan Lasheras and Igor Syratchev explain why klystrons are strategically important to the future of the field – and how CERN plans to boost their efficiency above 90%. Generating power ...
