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

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 ...

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 ...

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 ...

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 ...

Novel and established detectors that push technologies to new heights will allow the CMS collaboration to fully exploit the HL-LHC physics potential. Anne Dabrowski, Frank Hartmann and Paolo Rumerio ...

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 ...

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 ...

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 ...

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 ...
