The International Beam Instrumentation Conference (IBIC) is dedicated to exploring the physics and engineering challenges of beam diagnostic and measurement techniques for particle accelerators ...

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 ...

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, ...

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, ...

In the May 1966 issue of CERN Courier, A J Herz (Nuclear Physics Division) and W O Lock (Personnel Division) described the development of nuclear-emulsion detectors, highlighting a CERN experiment ...

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 ...

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 ...

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 ...

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 ...

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 ...
