ABSTRACT
We measure the top quark mass (m(t)) in p Ìp collisions at a center of mass energy âs = 1.96 TeV using dilepton t ÌtâW(+)bW(-) Ìbââ(+)ν(â)bâ(-) Ìν(â) Ìb events, where â denotes an electron, a muon, or a tau that decays leptonically. The data correspond to an integrated luminosity of 5.4 fb(-1) collected with the D0 detector at the Fermilab Tevatron Collider. We obtain m(t)=174.0±1.8(stat)±2.4(syst) GeV, which is in agreement with the current world average m(t)=173.3±1.1 GeV. This is currently the most precise measurement of m(t) in the dilepton channel.
