At the Topical Workshop on Proton-Antiproton Collider Physics in Rome from 12-14 January 1983, the first tentative evidence for observations of the W particle by the UA1 and UA2 collaborations is presented.

Out of the several thousand million collisions recorded, a handful give signals, which could correspond to the production of a W in the high-energy collision and its subsequent decay into an electron (or positron if the W is positively charged) and a neutrino
