Europe’s foremost particle-physics laboratory, CERN was established near Geneva in 1954 to stop the brain drain to the US that had begun during the Second World War, and to provide a force for unity in post-war Europe. Alongside technological innovations such as the World Wide Web, its contributions to fundamental science include the discovery of the W and Z bosons, the determination of the number of light neutrino families and the discovery of direct CP violation. CERN’s Large Hadron Collider – the highest energy machine in the world – is in the middle of a programme of exploration that has already yielded the discovery of the Higgs boson.
On 8 April, CERN unveiled plans for a major new facility for scientific education and outreach.
A strong tradition of innovation and ingenuity shows that, for CERN’s North Area, life really does begin at 40.
Linac2, the machine that feeds CERN’s accelerator complex with protons, has entered a well-deserved retirement after 40 years of service.
New muon end-cap wheels currently being installed in the ATLAS detector will provide precision tracking and triggering at high rates for Run 3 and beyond.
Proton beams are once again circulating in the LHC in preparation for Run 3.
New measurements of the rates of rare B-meson decays to electrons and muons open a further avenue through which to explore the flavour anomalies.
For the first time at any experiment, the CMS collaboration have observed longitudinally polarised W bosons in diboson production.
A new CMS analysis searches for anomalies in top-quark interactions with the Z boson using an effective-field-theory framework.
The LHCb experiment recently presented new results on the b → sμμ decay of a Bs meson to a φ meson and a dimuon pair.
NuFact 2021 brought together experimentalists, theorists and accelerator physicists in pursuit of CKM-level precision in neutrino physics.
By measuring the transverse momentum of photon pairs, and related observables, the strong interaction may be indirectly probed.
On 21 June, officials and journalists gathered at to mark CERN’s new flagship project for science education and outreach.
