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

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 ...

Oliver James of DNEG, which produced the striking black hole in the film Interstellar, describes the science behind visual effects and the challenges in this fast-growing industry. Gargantua A variant ...

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 ...

Patrick Koppenburg and Marco Pappagallo survey the 23 exotic hadrons discovered at the LHC so far. Twenty-three exotic states Five pentaquarks and 18 tetraquarks have been discovered so far at the LHC ...

With a new measurement imminent, the Courier explores the experimental results and theoretical calculations used to predict ‘muon g-2’ – one of particle physics’ most precisely known quantities and ...

On-chip acceleration pioneers Robert Byer, Joel England, Peter Hommelhoff and Roy Shiloh report on progress to miniaturise accelerators from centimetres to microns. Accelerators on a chip Forty long ...

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 ...

A major proposed upgrade of the LHCb detector for LHC Runs 5 and 6 would allow a wide range of flavour-physics observables to be explored with extreme precision. Lucia Grillo, Stefano Perazzini and ...

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 ...

Cosmologist and theoretical physicist Licia Verde discusses the current tension between early- and late-time measurements of the expansion rate of the universe. Shining light Licia Verde is ICREA ...

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 ...
