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 ...

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 ...

Marco Calviani describes major upgrades to the beam-intercepting devices that lie at the heart of CERN’s accelerator complex.

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.

The proton spin crisis Illuminating The 12 GeV CEBAF accelerator at Jefferson Lab may shed light on the source of the proton’s missing spin. Credit: DOE’s Jefferson Lab. Among many misconceptions in ...

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 ...

Alexander Lenz argues that the charm quark is an experimental and theoretical enigma that has the potential to shed light on the matter–antimatter asymmetry in the universe.

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.

Explaining the bizarre pattern of fermion types and masses has led theorists to suggest that the “flavour scale” could be at a much lower energy than previously thought.

The heavy-ion physics programme at LHC Run 3 will provide deep insights into the rich field of QCD phenomenology.

The past seven decades have seen remarkable cultural and technological changes. And CERN has been no passive observer. From modelling European cooperation in the aftermath of World War II to ...

Early-career researchers tell the Courier what they think is the key strategic issue for the future of high-energy physics. Accelerating into the future Seventy years after construction began on ...
