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.

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 ...

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

A 100 km tunnel hosting a circular electron–positron Higgs and electroweak factory would pave the way for an energy-frontier hadron collider.

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.

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 ...

20 years since coining the string-theory "landscape", Leonard Susskind describes the emerging connections between quantum mechanics and gravity.

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.

Rolf Widerøe operates one of his betatrons in 1953. Credit: Av Verdens Gang/NTB Scanpix The betatron is an early type of MeV-range electron accelerator which uses the electric field induced by a ...

Recent progress in understanding thorium’s nuclear structure could enable an ultra-accurate nuclear clock with applications in fundamental physics.

Volker Lindenstruth goes behind the scenes of a completely new computing model that allows the ALICE collaboration to merge online and offline data processing into a single software framework.

Orthodox quantum mechanics is empirically flawless, but founded on an awkward interface between quantum systems and classical probes. In this feature, Carlo Rovelli – himself the originator of the ...
