The discovery of a W particle

25 January 1983

In a press conference on 25 January, CERN announces news of the discovery of the W boson to the world. The UA2 team reserves judgment at this stage but further analysis soon convinces them. From their results both teams estimate the boson's mass at around 80 GeV, which is in excellent agreement with predictions from electroweak theory.
