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, ...
Recent experimental results hint that some electroweak processes are not lepton-flavour independent, contrary to Standard Model expectations. If the effect strengthens as more data are gathered, ...
Rolf Widerøe operates one of his betatrons in 1953. Credit: Av Verdens Gang/NTB Scanpix The betatron is an early type of MeV-range electron accelerator which uses the electric field induced by a ...
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 ...
Geared for discovery more so than delicacy, the LHC is defying expectations by rivalling lepton colliders for precision. Guillelmo Gomez-Ceballos and Jan Kretzschmar identify five measurements of the ...
The masses of the Higgs boson and the top quark hint that there must be physics beyond the Standard Model that prevents the universe from decaying into a new vacuum state, argues John Ellis. New ...
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 ...
Patrick Koppenburg and Marco Pappagallo survey the 23 exotic hadrons discovered at the LHC so far. Twenty-three exotic states Five pentaquarks and 18 tetraquarks have been discovered so far at the LHC ...
Edward Witten has spent almost 50 years at the forefront of theoretical and mathematical physics. Here he describes how the LHC and other recent results have impacted his view on nature, and asks ...
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, ...
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 ...
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 ...
