We present a search for dilepton events from tt¯ production with one electron or muon and one hadronically decaying τ lepton from the decay tt¯→(ℓνℓ)(τντ)bbú, (ℓ=e,μ), using the Collider Detector at Fermilab. In a 109pb−1 data sample of pp¯ collisions at √S=1.8TeV we expect ∼1 signal event and a total background of ∼2 events; we observe 4 candidate events (2eτ and 2μτ). Three of these events have jets identified as b candidates, compared to an estimated background of 0.28±0.02 events. © 1997 The American Physical Society.
