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 ...

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 ...

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 ...

The masses of the Higgs boson and the top quark hint that there must be physics beyond the Standard Model that prevents the universe from decaying into a new vacuum state, argues John Ellis. New ...

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 ...

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 ...

CERN’s Molflow software has become the de-facto industry standard for ultra-high- vacuum simulations. Roberto Kersevan and Marton Ady describe how it is now enabling space research and other branches ...

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, ...

Orthodox quantum mechanics is empirically flawless, but founded on an awkward interface between quantum systems and classical probes. In this feature, Carlo Rovelli – himself the originator of the ...

Jochen Klein and Marco van Leeuwen describe the physics motivation, detector concept and projected performance of a next-generation heavy-ion programme for LHC Runs 5 and 6. Brand new ALICE 3 is built ...

Innovation in superconducting radio-frequency (SRF) technology and applications is fundamental for the success of the High-Luminosity LHC (HL-LHC) project and the next-generation particle colliders ...

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, ...
