CERN celebrates the completion of the civil-engineering work for the High-Luminosity LHC (HL-LHC), the major upgrade of its flagship collider, the LHC

Highlights of the year at CERN, from the record-breaking start of LHC Run 3 to great particle physics results and much more

Simultaneous measurements of rare B-meson decays using the full LHC Run 1 and 2 data samples agree with the predictions of the Standard Model, superseding previous results that had indicated intriguing departures from the 50-year old theory

In their first Run 3 results, the ATLAS collaboration measured two Standard Model processes: the production of Z bosons and top-quark pairs

CMS has now released the complete set of proton-proton data taken from LHC Run 1, including the original findings used in the Higgs boson discovery

The finding will help space- and balloon-based searches for antimatter that may have originated from dark matter

The LHCb collaboration has released data from Run 1 of the LHC to the public for the first time, allowing research to be conducted by anyone in the world

The CAPP axion haloscope at the CAST experiment has hunted for axions from the Milky Way’s “halo” of dark matter, and has narrowed down the theoretical space in which to look for these hypothetical particles

CERN and Airbus UpNext sign a collaboration agreement to assess the use of superconducting technologies for future low-emission aeroplanes

Selected out of more than 22 500 applicants, CERN engineer Sławosz Uznański from Poland has been chosen as one of the 11 members of the ESA 2022 astronaut class in the reserve pool
