Abstract
We measure the top quark mass m(t) using <t(t)over bar> pairs produced in the DO detector by root s = 1.8 TeV <p(p)over bar> collisions in a 125 pb(-1) exposure at the Fermilab Tevatron. We make a two constrain t fit to m(t) in <t(t)over bar> --> bW(+)<(b)over bar W-> final states with one W decaying to <q(q)over bar> and the other to e nu or mu nu. Events are binned in fit mass versus a measure of probability for eve nts to be signal rather than background. Likelihood fits to the data y ield m(t) = 173.3 +/- 5.6(stat) +/- 6.2(syst) GeV/c(2).
