Abstract

We present an analysis of dilepton events originating from

t \bar{t}

production in

p \bar{p}

collisions at

\sqrt{s} = 1.8 TeV

at the Fermilab Tevatron Collider. The sample corresponds to an integrated luminosity of

109 \pm 7 {pb}^{- 1}

. We observe nine candidate events, with an estimated background of

2.4 \pm 0.5

events. We determine the mass of the top quark to be

M_{top} = 161 \pm 17 (stat) \pm 10 (syst) GeV {/ c}^{2}

. In addition, we measure a

t \bar{t}

production cross section of

{8.2}_{- 3.4}^{+ 4.4} pb

(where

M_{top} = 175 GeV {/ c}^{2}

has been assumed for the acceptance estimate).
