The 1983 UA1 experiment paper used proton–antiproton collisions at . A high-transverse momentum Electron candidate required a track matched to an electromagnetic particle shower, with little energy behind it in the hadronic particle calorimeter. Test beams checked Electron and pion responses; ordinary events and particle jet samples checked the imbalance resolution. Two searches, beginning with isolated Electrons and with missing transverse energy, converged on the same candidates. Conversion pairs, hadrons and heavy-flavor decays were examined as backgrounds.[ref]

The UA1 experiment was a particle physics experiment conducted at CERN, the European Organization for Nuclear Research, in the early 1980s. It was part of the larger family of experiments that contributed to the discovery of the W and Z bosons, which are fundamental particles responsible for the weak nuclear force. The UA1 collaboration was a prominent experiment at the Super Proton Synchrotron (SPS) collider and aimed to study proton-antiproton collisions.
