Abstract

We present a search for dilepton events from t (t) over bar production with one electron or muon and one hadronically decaying tau lepton from the decay t (t) over bar --> (l nu(l))(tau nu(tau))b (b) over bar, (l = e, mu)(-), using the Collider Detector at Fermilab. In a 109 pb(-1) data sample of p (p) over bar collisions at root s = 1.8 TeV we expect similar to 1 signal event and a total background of similar to 2 events; we observe 4 candidate events (2 e tau and 2 mu tau). Three of these events have jets identified as b candidates, compared to an estimated background of 0.28 +/- 0.02 events. [S0031-9007(97)04295-6].
