Sustainable HEP brings together the high-energy physics community to explore the intersection of particle physics and sustainability, covering topics such as energy efficiency, material use, ...

After a moment of turbulence, Norbert Holtkamp returns to Fermilab with a clear mandate: deliver DUNE, honour the laboratory’s legacy of bold leadership and reaffirm big science’s responsibility to ...

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 ...

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 ...

Breaking with decades of haloscope design, the ALPHA and MADMAX collaborations are pushing the search for dark matter into a promising new niche. High-mass haloscope Graduate student Heather Jackson ...

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 ...

In recent years, no Standard Model prediction has come under greater scrutiny than the magnetic moment of the muon. The Courier caught up with Muon g-2 Theory Initiative chair Aida El-Khadra on ...

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 ...

Michael Riordan surveys the extraordinary events of 1964 – a year that witnessed the birth of the quark model, the invention of the Higgs mechanism, the discovery of CP violation and the first ...

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 ...

Laser calibration Technical improvements by Fermilab’s Muon g-2 collaboration achieved a systematic uncertainty of 78 ppb on quantum corrections to the magnetic moment of the muon. Credit: R Hahn ...

David Wallace argues for the ‘decoherent view’ of quantum mechanics, where at the fundamental level there is neither probability nor wavefunction collapse – and for its purest incarnation, the ...
