Using LHC Run 2 data, CMS has precisely measured the rare decay of strange B-mesons to muon-antimuon pairs. While its properties agree with Standard Model predictions, it may provide clues to new discoveries in Run 3

French graphic novelist Benjamin Reiss took advantage of a stay in the Pays de Gex to visit the ISOLDE facility and soak up the world of science

A round of applause broke out in the CERN Control Centre on 5 July at 4.47 p.m. CEST when the Large Hadron Collider (LHC) detectors started recording high-energy collisions at the unprecedented energy of 13.6 TeV

The VELO (Vertex Locator), the most recent addition to LHCb, was successfully installed a few weeks before the start of Run 3

The collaboration has observed a new kind of “pentaquark” and the first-ever pair of “tetraquarks”

The collaborations have used the largest samples of proton–proton collision data recorded so far by the experiments to study the unique particle in unprecedented detail

The Large Hadron Collider is ready to once again start delivering proton collisions to experiments, this time at an unprecedented energy of 13.6 TeV, marking the start of the accelerator’s third run of data taking for physics

What’s so special about the Higgs boson? Why should I care? What’s next? If these questions torment you, head straight to home.cern.

How can we support members of our Laboratory in addressing conflict early on, before it reaches the Ombud’s Office?
