CERN entrepreneurship highlighted in global innovation report
The Global Innovation Index (GII) looks at innovation across 139 economies using 79 indicators and asks how economies can turn scientific breakthroughs into scalable ventures. CERN contributed to the latest edition of the report, launched on 29 September and entitled Powering entrepreneurs at the frontier of science, with a paper on CERN Venture Connect (CVC),

Predicting the socio-economic impact of the High-Luminosity LHC
In 1931, Paul Dirac predicted a particle with the same mass as the electron and the opposite charge. This particle, the “positron”, was observed the following year, in a cloud-chamber photograph taken by Carl Anderson. Of course, neither envisaged any medical applications of the discovery. But, today, PET scanners identify tumours by capturing the gamma

The disconnection of the LHC has begun
The 27 km circumference of the Large Hadron Collider (LHC) contains thousands of magnets of different types – dipoles, quadrupoles, sextupoles, octupoles, decapoles, etc. – which each play a very specific role. Among them are the inner triplets: sets of three quadrupoles (hence the name) located on either side of the four main LHC experiments

Strong evidence for quantum entanglement between Z bosons found by ATLAS and CMS
Quantum entanglement is certainly one of the stranger concepts to have emerged from the melting pot of 20th-century physics. Many great physicists, including Einstein, struggled to accept that the phenomenon could be real but, for decades now, the number of examples demonstrating it has been increasing. And, recently, the ATLAS and CMS Collaborations have added to these results by

NA64, a decade of hunting dark matter
In particle physics, energy is never lost. When particles collide or decay, all the initial energy they carry must be conserved in the resulting products, and a shortfall signals that something has escaped unseen. It was the energy missing from radioactive decays that led Wolfgang Pauli to propose the neutrino in 1930, a particle so elusive that it evaded detection for

Exceptional transport operations to make way for HiLumi LHC
We often hear about the remarkable components of the accelerators, but transporting this equipment sometimes requires measures that are just as impressive. Over the course of the third long shutdown (LS3), which started this summer, entire sections of the Large Hadron Collider and its detectors will be dismantled in order to make room for the

All CERN accelerators now on the road to HiLumi
CERN’s injector complex and Antimatter Factory took their final steps towards Long Shutdown 3 (LS3) this morning, as the last particle beams were extracted and the machines fell silent. This milestone follows the shutdown of the Large Hadron Collider (LHC) in June, which marked the beginning of LS3 for the Laboratory’s flagship accelerator. While the

ATLAS and CMS narrow in on double-Higgs production
Finding one Higgs boson was hard enough, but physicists at the Large Hadron Collider (LHC) are hunting for something even more elusive: pairs of Higgs bosons. At the recent International Conference on High Energy Physics 2026, the ATLAS and CMS Collaborations presented new constraints on the double-Higgs production rate, providing insight into how the Higgs

Positrons pass test for the Future Circular Collider
An experiment at the Paul Scherrer Institute (PSI) in Switzerland has successfully produced, captured and transported positrons using a novel system developed for CERN’s proposed Future Circular Collider (FCC). The results show that the key elements of the FCC positron-source concept can operate together, representing an important advance for this technically demanding aspect of the

Final tests for the AMS upgrade before spaceflight
A new layer of silicon sensors is being tested at CERN before being sent to the International Space Station
