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

Donations to “Light their Spark”, the regular giving programme of the CERN & Society Foundation, will fuel opportunities for students, teachers and scientists across the world

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
