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, ...

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 ...

In lead collisions at the LHC, some of the strongest electromagnetic fields in the universe bombard the inside of the beam pipe with radioactive gold. By following the collision fragments, John Jowett ...

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 ...

Vivian Poulin asks if the tension between a direct measurement of the Hubble constant and constraints from the early universe could be resolved by new physics. On large scales the dominant motion of ...

Fermilab’s Proton Improvement Plan II (PIP-II) is relying on international collaborations to shape the future of accelerator-based particle physics in the US. Lia Merminga and Eduard Pozdeyev provide ...

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 ...

Jochen Klein and Marco van Leeuwen describe the physics motivation, detector concept and projected performance of a next-generation heavy-ion programme for LHC Runs 5 and 6. Brand new ALICE 3 is built ...

Oliver James of DNEG, which produced the striking black hole in the film Interstellar, describes the science behind visual effects and the challenges in this fast-growing industry. Gargantua A variant ...

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 ...

What a proton is depends on how you look at it, or rather on how hard you hit it. A century after Rutherford’s discovery, our picture of this ubiquitous particle is coming into focus, says Amanda ...

The Courier matched photos from CERN’s first 25 years to current experts and asked them to reflect on how much has changed across 70 years of science. The past seven decades have seen remarkable ...
