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 ...

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 ...

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 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 ...

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 ...
