In October, the Circular Electron–Positron Collider (CEPC) study group completed its full suite of technical design reports, ...

Pierre Darriulat, who was spokesperson for the UA2 collaboration between 1978 and 1985, looks back at the events surrounding the discovery of the W and Z particles at CERN in 1983. The decade between ...

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 ...

Aurélien Barrau on why multiple universes should be taken seriously. Is our entire universe a tiny island within an infinitely vast and infinitely diversified meta-world? This could be either one of ...

CERN Courier is essential reading for the global high-energy physics community. The website and associated print magazine highlight the latest developments in particle physics and related fields, ...

Tiny black holes could offer a richer view of physics than their better known, moremassive relations, as Aurélien Barrau and Julien Grain explain. Unification is the dream of high-energy physicists.

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 ...

The story of a forerunner to today’s mobile-phone screens. The SPS control room in 1977. Ted Wilson and Rae Stiening are at the desk, with its touch screens; Bent Stumpe and George Shering stand ...

Advanced radio-frequency crab cavities are to be tested for the first time in a proton beam, a vital step towards the high-luminosity LHC upgrade. Cryomodule containing two crab cavities (cuboidal ...

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 ...

The recently installed, upgraded ALICE inner tracking system is the largest pixel detector ever built and the first at the LHC to use monolithic active pixel sensors, describe Luciano Musa and ...

What a proton is depends on how you look at it, or rather on how hard you hit it. A century after Rutherford’s discovery, our picture of this ubiquitous particle is coming into focus, says Amanda ...
