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 ...

From their beginnings at CERN half a century ago, writes Chris Damerell, silicon pixel detectors for particle tracking have blossomed into a vast array of beautiful creations that have driven numerous ...

The development at CERN of magnesium diboride cables and other advanced superconducting systems for the High-Luminosity LHC is also driving applications beyond fundamental research, describes Amalia ...

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 ...

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.

CERN is home to a unique innovation ecosystem pioneering advances in vacuum science, technology and engineering. Paolo Chiggiato and Paul Cruikshank provide an insider take. Gearing up 2021 promises ...

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.

Of the Standard Model’s three gauge couplings, the one between quarks and gluons is by far the least well known. Harvey Meyer recounts the decades of lattice QCD behind its recent determination to ...

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 ...

Louis Lyons traces the origins of the “five sigma” criterion in particle physics, and asks whether it remains a relevant marker for claiming the discovery of new physics. Disentanglement A Jackson ...

Peter Thirolf, Benedict Seiferle and Lars von der Wense describe how recent progress in understanding thorium’s nuclear structure, and new upcoming results, could enable an ultra-accurate nuclear ...

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, ...
