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 ...

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 ...

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, ...

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.

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 ...

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 ...

An electron–positron collider to follow the LHC will produce copious Higgs bosons, yielding precise knowledge of this unique particle, explain Keith Ellis and Beate Heinemann. The novelty of the Higgs ...

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 ...

The search for heavy particles beyond the direct reach of the LHC. Particle physics provides no certain knowledge about this scale but the hope is that the new particles might be produced directly in ...

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 ...
