Description
We report the results of two searches made on data recorded at the CERN SPS Proton-Antiproton Collider: one for isolated large-Esub(T) electrons, the other for large-Esub(T) neutrinos using the technique of missing transverse energy. Both searches converge to the same events, which have the signature of a two-body decay of a particle mass in excess of 70 GeV/c2. The topology as well as the number of events fits well the hypothesis that they are produced by the process anti p + p -> Wsup(+-) + X, with Wsup(+-) -> esup(+-) + ν; where Wsup(+-) is the Intermediate Vector Boson postulated by the unified theory of weak and electromagnetic interactions.
