Sustainable HEP brings together the high-energy physics community to explore the intersection of particle physics and sustainability, covering topics such as energy efficiency, material use, ...

From targets to absorbers, beam-intercepting devices are vital to CERN’s accelerator complex. Marco Calviani describes the major upgrades taking place to prepare for the high-luminosity LHC, and the ...

Louis Lyons traces the origins of the “five sigma” criterion in particle physics, and asks whether it remains a relevant marker for claiming the discovery of new physics. Disentanglement A Jackson ...

André de Gouvêa explains why neutrino masses imply the existence of new fundamental fields. Misfits Massive neutrinos are not part of the Standard Model. Credit: Symmetry After all these years, ...

Vivian Poulin asks if the tension between a direct measurement of the Hubble constant and constraints from the early universe could be resolved by new physics. On large scales the dominant motion 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 ...

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 ...

The unknown origin of the matter–antimatter asymmetry observed in the universe looms large in the scientific imagination. Boris Kayser explains how neutrino physicists are now closing in on a crucial ...

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 ...

Before the discovery of quarks, Nicola Cabibbo arrived at the correct formulation of the mechanism responsible for quark mixing. Luciano Maiani, Guido Martinelli and Giorgio Parisi recount Cabibbo’s ...

In the summer of 1968, while a visitor in CERN’s theory division, Gabriele Veneziano wrote a paper titled “Construction of a crossing-symmetric, Regge behaved amplitude for linearly-rising ...

Enrico Chesta, Véronique Ferlet-Cavrois and Markus Brugger highlight seven ways CERN and ESA are working together to further fundamental exploration and innovation in space technologies. Sky map The ...
