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 ...
An electron–positron collider to follow the LHC will produce copious Higgs bosons, yielding precise knowledge of this unique particle, explain Keith Ellis and Beate Heinemann. The novelty of the Higgs ...
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, ...
Rolf Widerøe operates one of his betatrons in 1953. Credit: Av Verdens Gang/NTB Scanpix The betatron is an early type of MeV-range electron accelerator which uses the electric field induced by a ...
Geared for discovery more so than delicacy, the LHC is defying expectations by rivalling lepton colliders for precision. Guillelmo Gomez-Ceballos and Jan Kretzschmar identify five measurements of the ...
With less than two years of LHC operations before the start of long-shutdown three (LS3), when the main installation phase of the High-Luminosity LHC will begin, Oliver Brüning and Markus Zerlauth ...
Recent experimental results hint that some electroweak processes are not lepton-flavour independent, contrary to Standard Model expectations. If the effect strengthens as more data are gathered, ...
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 ...
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 ...
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 ...
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 ...
