Measurement of the Top Quark Mass with the Collider Detector at Fermilab

Abstract

We present a new measurement of the top quark mass in events in which both bosons from top quarks decay into lepton (). We use events collected by the CDF experiment from collisions at \sqrt s=1.8 TeV at the Tevatron collider. We measure a top quark mass of 167.4 \pm 10.3(stat) \pm 4.8(syst) GeV/c^2 from a sample of eight events. We combine this result with previous CDF measurements in other decay channels to obtain a mass value of 176.0 \pm 6.5 GeV/c^2.
