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, ...

From targets to absorbers, beam-intercepting devices are vital to CERN’s accelerator complex. Marco Calviani describes the major upgrades taking place to prepare for the high-luminosity LHC, and the ...

CERN Courier is essential reading for the global high-energy physics community. The website and associated print magazine highlight the latest developments in particle physics and related fields, ...

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 ...

Explaining the bizarre pattern of fermion types and masses has led theorists to explore more complex symmetry groups than the Standard Model’s, with recent work suggesting that the “flavour scale” ...

Either new particles are keeping the Higgs boson light, or the universe is oddly fine-tuned for our existence. Nathaniel Craig goes down the rabbit hole of the electroweak hierarchy problem.

Frontier instruments like the LHC and its detectors not only push back the boundaries of our knowledge, but also catalyse innovative technology for medical applications, writes Manuela Cirilli.

Tiny black holes could offer a richer view of physics than their better known, moremassive relations, as Aurélien Barrau and Julien Grain explain. Unification is the dream of high-energy physicists.

In the summer of 1968, while a visitor in CERN’s theory division, Gabriele Veneziano wrote a paper titled “Construction of a crossing-symmetric, Regge behaved amplitude for linearly-rising ...

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 ...

Steven Weinberg talks to CERN Courier about his seminal 1967 work and discusses where next for particle physics following the discovery of the Higgs boson. Steven Weinberg photographed at the ...

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 ...
