Abstract

We present a search for dilepton events from

t \bar{t}

production with one electron or muon and one hadronically decaying

τ

lepton from the decay

t \bar{t} \to (ℓ ν_{ℓ}) (τ ν_{τ}) b \bar{b}

,

(ℓ = e, μ)

, using the Collider Detector at Fermilab. In a

109 {pb}^{- 1}

data sample of

p \bar{p}

collisions at

\sqrt{s} = 1.8 TeV

we expect

\sim 1

signal event and a total background of

\sim 2

events; we observe 4 candidate events (

2 e τ

and

2 μ τ

). Three of these events have jets identified as

b

candidates, compared to an estimated background of

0.28 \pm 0.02

events.
