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, ...
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 ...
Steven Weinberg talks to CERN Courier about his seminal 1967 work and discusses where next for particle physics following the discovery of the Higgs boson. Steven Weinberg photographed at the ...
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 ...
Updated measurements by LHCb of the angular distributions of a rare neutral B meson decay add fresh intrigue to the flavour puzzle.
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 ...
With a new measurement imminent, the Courier explores the experimental results and theoretical calculations used to predict ‘muon g-2’ – one of particle physics’ most precisely known quantities and ...
In lead collisions at the LHC, some of the strongest electromagnetic fields in the universe bombard the inside of the beam pipe with radioactive gold. By following the collision fragments, John Jowett ...
If dark matter couples feebly enough to evade direct detection, it may still betray itself by stealing energy from a beam. Paolo Crivelli, Laura Molina-Bueno and Sergei Gninenko look back on 10 years ...
A report from the ALICE and ATLAS experiments. The ATLAS and ALICE collaborations have announced the first results of a new way to measure the “radial flow” of quark–gluon plasma (QGP). The two ...
With the story of quarkonia entering its final chapter, John Ellis shares personal recollections of five decades of discoveries and debates about the simplest composite object in QCD, whose history is ...
Michèle Levi takes a tour through the past, present and future of Effective Field Theory, with applications ranging from LHC physics to cosmology. LHC physics Effective field theory enables a deeper ...
