Observation of single isolated electrons of high transverse momentum in events with missing transverse energy at the CERN p collider

摘要

We report the results of a search for single isolated electrons of high transverse momentum at the CERN 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 , with W→e+ν, where W± is the charged Intermediate Vector Boso postulated by the unified electroweak theory.
