Abstract

We present a new measurement of the top quark mass in tt events in which both W bosons from top quarks decay into leptons (e ν, μ ν). We use events collected by the CDF experiment from pp collisions at √ s=1.8 TeV at the Tevatron collider. We measure a top quark mass of 167.4 ± 10.3 (stat) ± 4.8 (syst) GeV/c2 from a sample of eight events. We combine this result with previous CDF measurements in other decay channels to obtain a final mass value of 176.0 ± 6.5 GeV/c2.
