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 ...

Big Science, Innovation & Societal Contributions: The Organisations and Collaborations in Big Science Experiments, edited by Shantha Liyanage, Markus Nordberg and Marilena Streit-Bianchi, Oxford ...

How are community inputs and debates shaping the ongoing update to the European strategy for particle physics? The Courier consults two scientists tasked with representing CERN Member States and the ...

The most common neutrino interactions are the most difficult to detect. But thanks to advances in detector technology, coherent elastic neutrino–nucleus scattering (CEνNS) is emerging from behind ...

Quasi-bound candidate An event display of an interaction consistent with the formation of toponium in the ATLAS detector. The final state includes two b jets (turquoise cones), a muon (red line) and ...

A report from the ATLAS experiment. Fig. 1. Combined Run 2 and Run 3 results for weighted dimuon (top) and Zγ (above) invariant mass spectra, summed over all event categories. The data are compared to ...

Robert Brandenberger argues that the unchanging cosmological constant of the ΛCDM model is theoretically problematic. Galaxies and quasars Measurements by the Dark Energy Spectroscopic Instrument hint ...

Big science requires long-term planning. In June, the US National Academies of Sciences, Engineering, and Medicine published an unprecedented 40-year strategy for US particle physics titled Elementary ...

A report from the CMS experiment. In addition to giving mass to elementary particles, the Brout–Englert–Higgs mechanism provides a testing ground for the fundamental symmetries of nature. In a recent ...

Narrow sprays of particles called jets erupt from high-energy quarks and gluons. The ALICE collaboration has now measured so-called energy–energy correlators (EECs) of charm-quark jets for the first ...
