Eliezer Rabinovici reflects on the 4th International Symposium on the History of Particle Physics, and on the two decades during which the field grew to a planetary scale. The post When particles went global appeared first on CERN Courier .

If dark matter couples feebly enough to evade direct detection, it may still betray itself by stealing energy from a beam. NA64 has put this principle to work for 10 years. The post Ten years at the missing-energy frontier appeared first on CERN Courier .

Xsuite drew CERN's fragmented beam-simulation tools into a single framework, used to operate existing colliders, design future ones and model medical accelerators. The post The Swiss Army knife of beam simulation appeared first on CERN Courier .

The updated European Strategy for Particle Physics recommends the FCC-ee as the next flagship project at CERN. The post CERN Council updates the European Strategy appeared first on CERN Courier .

The LHC has entered its third Long Shutdown after a Run 3 that surpassed expectations, beginning four years of upgrades towards the High-Luminosity LHC. The post The LHC completes its third run appeared first on CERN Courier .

Authors who submit papers containing unchecked LLM output will risk a year's suspension from arXiv. The post arXiv’s one-strike rule on AI appeared first on CERN Courier .

ALPHA has measured the ground-state hyperfine splitting of antihydrogen a hundred times more precisely than before, sharpening its test of CPT symmetry. The post Antihydrogen toes the line appeared first on CERN Courier .

A bound galaxy protocluster with hot, X-ray-emitting gas has been found just one billion years after the Big Bang. The post A hot start for cluster formation appeared first on CERN Courier .

Council president Costas Fountas reflects on the recommendation of FCC-ee as CERN’s preferred next flagship collider, and the path to a decision in 2028. The post Regrouping for success appeared first on CERN Courier .

ATLAS has observed that nucleons near the edge of a nucleus have different parton distribution functions from those near its centre. The post A light on partons at the nuclear edge appeared first on CERN Courier .

CMS has searched for the rare decay of the W boson into three light charged hadrons, setting the most stringent limit yet on its branching fraction. The post W boson decays to three charged hadrons appeared first on CERN Courier .

LHCb has observed a new doubly charmed baryon, marking the first new particle found with its upgraded detector. The post A new doubly charmed baryon appeared first on CERN Courier .

ALICE has measured the elliptic flow of the hypertriton for the first time, finding that it follows the collective motion of the medium. The post Collective flow in hypernuclei appeared first on CERN Courier .

Around 100 specialists gathered at CERN to take stock of quantum observables at colliders, a field grown from theoretical curiosity into a body of experimental results. The post All entangled around the collider appeared first on CERN Courier .

PLANCK 2026 brought more than 250 theorists to CERN to confront puzzles of scale, from the mass of dark matter to the hierarchy between the Higgs and Planck scales. The post Theorists ponder across scales appeared first on CERN Courier .

IPAC'26 drew more than 1500 accelerator physicists to Deauville to discuss flagship colliders, light sources, novel acceleration techniques and machine learning. The post Accelerator experts meet in Normandy appeared first on CERN Courier .

CPOD26 gathered more than 100 researchers at CERN to hunt for the QCD critical point, where the crossover to quark-gluon plasma becomes a first-order transition. The post QCD cartographers gather at CERN appeared first on CERN Courier .

LoopFest returned to Brookhaven with the latest in precision quantum field theory, from multi-loop calculations and SMEFT fits to machine learning and quantum information. The post Precision loops back to Brookhaven appeared first on CERN Courier .

Cosmic Pi, an open-source detector developed at CERN, measured cosmic rays from pole to pole. The post Cosmic rays from pole to pole appeared first on CERN Courier .

Jim Baggott’s Discordance is an attempt to describe the history of cosmology throughout the past century or more, delving into some of its less explored aspects. The post From the golden age to the Hubble wars appeared first on CERN Courier .
