Measurement of the top-quark mass in pp? collisions using events with two leptons
Original language description
We present a measurement of the top quark mass (mt) in pp? collisions at s=1.96 TeV using tt? events with two leptons (ee, e?, or ??) and accompanying jets in 4.3fb1 of data collected with the D0 detector at the Fermilab Tevatron collider. We analyze thekinematically underconstrained dilepton events by integrating over their neutrino rapidity distributions. We reduce the dominant systematic uncertainties from the calibration of jet energy using a correction obtained from tt? events with a final state of a single lepton plus jets. We also correct jets in simulated events to replicate the quark flavor dependence of the jet response in data. We measure mt=173.72.8(stat)1.5(syst) GeV and combining with our analysis in 1 fb1 of preceding data we measure mt=174.02.4(stat)1.4(syst) GeV.
