Measurement of the top quark mass in the dilepton channel

Abstract:
We report a measurement of the top quark mass using six candidate events for the process pp̄→tt̄+X →l+vbl-v̄b̄+X, observed in the D0 experiment at the Fermilab pp̄ collider. Using maximum likelihood fits to the dynamics of the decays, we measure a mass for the top quark of mt=168.4±12.3(stat) ±3.6(syst) Gev. We combine this result with our previous measurement in the tt̄→l+jets channel to obtain mt=172.1 ± 7.1 GeV as the best value of the mass of the top quark measured by D0. ©1999 The American Physical Society.
