CERN Accelerating science

The measurement is the most precise yet made by a single experiment

New ATLAS measurement of lepton flavour universality, a key feature of the Standard Model, in decays of the W boson is more precise than all previous measurements combined

The experiment is designed to detect very feebly interacting particles, including candidate dark-matter particles

CERN’s dedicated heavy-ion physics experiment, ALICE, is upgrading its Inner Tracking System and adding a forward calorimeter for the next phase of the LHC upgrade

The result has implications for future searches for rare beauty meson decays and for the interpretation of results from the Fermilab g-2 experiment

The collaboration has also made publicly available the software that it developed to search for the unique particle

How an evacuation of the CMS experimental cavern has provided invaluable human behaviour data to improve emergency preparedness for complex underground facilities

On 9 April 2024, a ceremony at CERN marked the donation of computing equipment to the Tshwane University of Technology in South Africa

The award ceremony is open to everyone and will take place on Monday 13 May 2024 at 6.30 p.m. at the Victoria Hall in Geneva

The new CERN Ombud will take up her duties on 1 May

Almost the whole accelerator complex is now in “physics mode”, routinely delivering the various types of beam to the different physics facilities and experiments. Notably, the intensity ramp-up in the LHC is progressing remarkably well
