A new generation of accelerator and reactor experiments is opening an era of high-precision neutrino measurements to tackle questions such as leptonic CP violation, the mass hierarchy and the ...

Thanks to new theory calculations and keenly awaited measurements of the magnetic moment of the muon, a longstanding anomaly may soon be resolved either in favour of new physics or the Standard Model.

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 ...

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 ...

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, ...

The Next Ion Medical Machine Study (NIMMS) aims to leverage CERN technologies and expertise in accelerators to design a new generation of light-ion accelerators for medicine. Ions for therapy How the ...

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 ...

Before the discovery of quarks, Nicola Cabibbo arrived at the correct formulation of the mechanism responsible for quark mixing. Luciano Maiani, Guido Martinelli and Giorgio Parisi recount Cabibbo’s ...

The Courier matched photos from CERN’s first 25 years to current experts and asked them to reflect on how much has changed across 70 years of science. The past seven decades have seen remarkable ...

A 100 km tunnel hosting a circular electron–positron collider as a first stage towards a 100 TeV proton–proton collider would probe new phenomena coupled to the Higgs and electroweak sectors with ...

Alexander Lenz argues that the charm quark is an experimental and theoretical enigma that has the potential to shed light on the matter–antimatter asymmetry in the universe. Threading the needle The ...

The VHEE 2020 International Workshop saw more than 400 scientists gather virtually to evaluate the production of very high-energy electrons for radiotherapy. High-tech A dosimetry experiment for VHEE ...
