Abstract

We observe hadronic W decays in t (t) over bar --> W(--> l nu) + greater than or equal to 4 jet events using a 109 pb(-1) data sample of p (p) over bar collisions at root s = 1.8 TeV collected with the Collider Detector at Fermilab. A peak in the dijet invariant mass distribution is obtained that is consistent with W decay and inconsistent with the background prediction by 3.3 sigma. From this peak we measure the W mass to be 77.2 +/- 4.6(stat + syst) GeV/c(2). This result demonstrates the presence of a second W boson in t (t) over bar candidates in the W(--> l nu) + greater than or equal to 4 jet channel.
