Find out how CERN is celebrating the 90th birthday of former Director-General and Nobel Prize laureate Carlo Rubbia, and how you can be involved

The eagerly awaited result is the most precise measurement of the W mass made at the LHC so far, and is in line with the prediction from the Standard Model of particle physics

Carlo Rubbia’s name is closely related to the discovery of the W and Z particles at CERN. In 1984, he was awarded the Nobel Prize in Physics, together with Simon van der Meer, for the work he had done as head of the UA1 collaboration

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

CERN Science Gateway will host its first scientific event to celebrate 50 years since Gargamelle discovered neutral currents and 40 years since UA1 and UA2 discovered the W and Z bosons

On 31 October 2023, we mark the 50th anniversary of the observation of neutral currents and the 40th anniversary of the discovery of the W and the Z bosons with a symposium in the new Science Gateway auditorium

An improved ATLAS measurement of the W boson mass is in line with the Standard Model of particle physics

Forty years ago today, physicists at CERN announced to the world that they had discovered the electrically charged carrier of the weak force, one of nature’s four fundamental forces

Joint-polarisation measurements of the W and Z bosons provide new opportunities to look for physics beyond the Standard Model

The direct discovery of the W and Z bosons at the SppS in 1983 provided solid experimental support for the existence of the Higgs boson
