Radiopharmaceuticals based on novel radionuclides have, for the first time, reached blockbuster proportions. Thierry Stora explains why high-energy physics has an essential role to play in scaling up ...

Ezio Todesco charts the future of high-field dipole magnets – a technology set to advance the boundaries of high-energy physics and the societal applications of superconductivity. Frontier ...

Six out of 1339 Six anomalous images of galaxies identified by artificial intelligence, including: a galactic merger (top right); a “collisional ring” galaxy that has been smashed by a secondary ...

A report from the LHCb experiment. Fig. 1. Distribution of the longitudinal momentum fraction z of charged hadrons in light- (green/orange), charm- (blue) and beauty-quark-initiated (purple) jets. The ...

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 ...

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 ...

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 ...

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 ...

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 ...

Vivian Poulin asks if the tension between a direct measurement of the Hubble constant and constraints from the early universe could be resolved by new physics. On large scales the dominant motion of ...

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 ...
