What was discovered

By converting the SPS into a proton-antiproton collider thanks to Van der Meer's stochastic cooling, UA1 and UA2 observe the W (January) and Z (May) bosons with the predicted masses of 80 and 91 GeV. The mediators of the weak force exist.

Nobel Prize for Rubbia and Van der Meer in 1984.
