The observed mass of the Higgs boson is, from the theoretical point of view, unnaturally small. This conundrum is forcing physicists to explore exotic explanations.

Following the winter shutdown, the injectors and accelerators are preparing for the 2023 data-taking season

Representatives of CERN, the United Nations Office at Geneva and other organisations held a two-day workshop to discuss the future of Indico, a CERN-created, open source platform for organising events

Representatives of the International Committee of the Red Cross (ICRC) came to CERN on Friday, 24 March for the first in a series of knowledge-sharing sessions on free and open source technologies

The ATLAS and CMS collaborations have both observed the simultaneous production of four top quarks, a rare phenomenon that could hold the key to physics beyond the Standard Model

Arts at CERN and Copenhagen Contemporary join forces and announce the first open call for Collide Copenhagen

With the progressive recommissioning of the injectors – including, now, the SPS – the various types of beam are being set up and are gradually reaching the downstream accelerators

The first observation of collider neutrinos at the LHC paves the way for exploring new physics scenarios

A second 7.2-metre-long HL-LHC triplet quadrupole has reached the currents needed for 7 TeV operation, with higher performances
