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

الأصل · EN

We present a new measurement of the top quark mass in t t events in which both W bosons from top quarks decay into lepton (e ν,μν). We use events collected by the CDF experiment from p p 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 mass value of 176.0 ± 6.5 GeV/c².
