Observation of Single Isolated Electrons of High Transverse Momentum in Events with Missing Transverse Energy at the CERN p Collider
Phys. Lett. 122B (1983) 476;

Abstracts
We report the results of a search for single isolated electrons of high transverse momentum at the CERN p collider. Above 15 GeV/c, four events are found having large missing transverse energy along a direction opposite in azimuth to that of the high-pT electron. Both the configuration of the events and their number are consistent with the expectations from the process p W anything, with W e , where W is the charged Intermediate Vector Boson postulated by the unified electroweak theory.
