Coauthored the search for electron-Positron pairs in proton-antiproton collisions that reported eight candidate Z boson events. Four events were used to estimate the new particle's mass, connecting the pair signal with the neutral mediator of the electroweak interaction.[ref]

The 1983 UA2 experiment Z boson paper reports eight candidate electron pairs, including radiative decays, at . Four events entered its invariant mass determination. The published result was , the second uncertainty systematic. These are that paper's reported numbers, not inputs fitted to the illustration below.[ref]
