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, ...

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 ...

What is the fate of the universe? Why is there more matter than antimatter? What lurks beyond the Standard Model? Valentina Cairo and Steven Lowette explore the physics reach of the High-Luminosity ...

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 ...

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 ...

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 ...

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 ...

Nuria Catalan Lasheras and Igor Syratchev explain why klystrons are strategically important to the future of the field – and how CERN plans to boost their efficiency above 90%. Generating power ...

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 ...

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 ...

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 ...

Marek Karliner and Jonathan Rosner ask what makes tetraquarks and pentaquarks tick, revealing them to be at times exotic compact states, at times hadronic molecules and at times both – with much still ...
