If dark matter couples feebly enough to evade direct detection, it may still betray itself by stealing energy from a beam. Paolo Crivelli, Laura Molina-Bueno and Sergei Gninenko look back on 10 years ...
A bound galaxy protocluster with hot, X-ray-emitting gas has been found just one billion years after the Big Bang.
The universe is a cosmic web, woven from vast filaments that connect galaxies and clusters. Elena Pinetti explains how these elusive threadlike structures are opening a new window on the nature of ...
Neutrino beams lack the precision that modern oscillation experiments demand. Laura Munteanu, Mathieu Perrin-Terrin and Stephen Dolan describe how neutrino tagging, proposed in 1979 and demonstrated ...
The European Strategy has recommended the FCC-ee as CERN’s next flagship collider. The case for it, Alain Blondel argues, rests on 50 years of inventions and discoveries. Alain Blondel is emeritus ...
Long-established in accelerator physics, bent crystals are now being explored as tools to measure the fundamental properties of short-lived charm baryons. Halo extraction The first bent crystal of the ...
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 ...
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 ...
Breaking with decades of haloscope design, the ALPHA and MADMAX collaborations are pushing the search for dark matter into a promising new niche. High-mass haloscope Graduate student Heather Jackson ...
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 ...
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 ...
Michael Riordan surveys the extraordinary events of 1964 – a year that witnessed the birth of the quark model, the invention of the Higgs mechanism, the discovery of CP violation and the first ...
